Atlas Rising - An Eco-Friendly Approach To Crypto Mining.
Mining crypto currencies has never been as costly as now due to the high electric power consumption and will be more costlier in the upcomming future as the whole blockchain ecosystem explodes. These mining activites are alot taxing on the natural ecosystem as alot of power in many countries comes from fossil fuel exploitations. Atlas Rising, a company in Texas is aiming in alleviating this environmental exploitation by taking a new approach to mining crypto currency, by the use of "Solar Energy". The majority of the mined asset goes to the pay out the reward for the Rising token holders and a certain percentage of the money in the vault and other for buying more Solar panels resulting in more eco-friendly mining resulting in more incentivised rewards to token holders and further increasing the net value of the vault which increases the value of Rising Token. A portion of the money invested to buy the token goes into the vault in form of major top tier crypto asset like BTC ,ETH ,LTC etc, a portion for trading, a portion for masternodes , a portion in staking and a portion in increasing Solar Mining Capacity. As a result not only the investors make a steady risk free profit but also as a whole environmental ecosystem is also preserved and benefits from Solar Energy with the innovative project.

How long until the issue of blocksize is brought up again for the Bitcoin Core community?
From the looks of it, it seems like there is eventually going to be further division in the Bitcoin Core community in the future, though that division may not be obcious right now because of the censored discussion on Bitcoin, and the fact that everyone at this moment is okay with full blocks and high fees. At some point, Bitcoin absolutely will have to raise its blocksize limit because on-chain fees can't be hundreds of dollars per transaction. Even with transaction batching for Lightning, it still doesn't seem viable to keep the blocksize limit so low... I've talked to other Bitcoin supporters and maximalists about increasing the blocksize, and it usually boils down to a few views/perspectives on the whole congestion situation with BTC:
"Increasing the blocksize (hardfork) is only acceptable if there is near 100% consensus among the community and hashpower since hardforks create a chain with new consensus rules"
"There is no need to increase the blocksize because almost all activity will happen off-chain with Lightning Network transactions. Institutions and banks will pay the high on-chain fees if and when they have to make high-value settlement transactions"
"The blocksize is already too large and should be softforked to be lower so that sync times improve, and more people can run full-nodes."
Right now the fee situation on Bitcoin is pretty bad, but it will only get worse with adoption. It already seems like the idea of achieving consensus for a hardfork is near impossible due to the nature of discussion on the Bitcointalk forum and Bitcoin subreddit (both owned by theymos). It directly states in the subreddit rule section that:
Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted.
The issue with this is the fact that this also includes even proposing a hardfork. I've seen discussions about even putting forward a BIP that proposes bigger blocks get completely censored or deleted by Bitcoin mods. So the first idea that hardforks will happen later on seems extremely unrealistic. The second idea is in direct conflict with the first one because it asserts an argument that opposes the first one. If blocksize doesn't and shouldn't be increased (and are fine the way they are), this will also cause division in the community. The third idea is also in conflict with the first and the second, which will also likely result in division. When will this division become much more evident in the Bitcoin Core community, causing another split for Bitcoin? It's bound to happen at some point, but maybe not today.
Maybe it's time to discuss bitcoin's history again. Credit to u/singularity87 for the original post over 3 years ago. People should get the full story of bitcoin because it is probably one of the strangest of all reddit subs. bitcoin, the main sub for the bitcoin community is held and run by a person who goes by the pseudonym u/theymos. Theymos not only controls bitcoin, but also bitcoin.org and bitcointalk.com. These are top three communication channels for the bitcoin community, all controlled by just one person. For most of bitcoin's history this did not create a problem (at least not an obvious one anyway) until around mid 2015. This happened to be around the time a new player appeared on the scene, a for-profit company called Blockstream. Blockstream was made up of/hired many (but not all) of the main bitcoin developers. (To be clear, Blockstream was founded before mid 2015 but did not become publicly active until then). A lot of people, including myself, tried to point out there we're some very serious potential conflicts of interest that could arise when one single company controls most of the main developers for the biggest decentralised and distributed cryptocurrency. There were a lot of unknowns but people seemed to give them the benefit of the doubt because they were apparently about to release some new software called "sidechains" that could offer some benefits to the network. Not long after Blockstream came on the scene the issue of bitcoin's scalability once again came to forefront of the community. This issue came within the community a number of times since bitcoins inception. Bitcoin, as dictated in the code, cannot handle any more than around 3 transactions per second at the moment. To put that in perspective Paypal handles around 15 transactions per second on average and VISA handles something like 2000 transactions per second. The discussion in the community has been around how best to allow bitcoin to scale to allow a higher number of transactions in a given amount of time. I suggest that if anyone is interested in learning more about this problem from a technical angle, they go to btc and do a search. It's a complex issue but for many who have followed bitcoin for many years, the possible solutions seem relatively obvious. Essentially, currently the limit is put in place in just a few lines of code. This was not originally present when bitcoin was first released. It was in fact put in place afterwards as a measure to stop a bloating attack on the network. Because all bitcoin transactions have to be stored forever on the bitcoin network, someone could theoretically simply transmit a large number of transactions which would have to be stored by the entire network forever. When bitcoin was released, transactions were actually for free as the only people running the network were enthusiasts. In fact a single bitcoin did not even have any specific value so it would be impossible set a fee value. This meant that a malicious person could make the size of the bitcoin ledger grow very rapidly without much/any cost which would stop people from wanting to join the network due to the resource requirements needed to store it, which at the time would have been for very little gain. Towards the end of the summer last year, this bitcoin scaling debate surfaced again as it was becoming clear that the transaction limit for bitcoin was semi regularly being reached and that it would not be long until it would be regularly hit and the network would become congested. This was a very serious issue for a currency. Bitcoin had made progress over the years to the point of retailers starting to offer it as a payment option. Bitcoin companies like, Microsoft, Paypal, Steam and many more had began to adopt it. If the transaction limit would be constantly maxed out, the network would become unreliable and slow for users. Users and businesses would not be able to make a reliable estimate when their transaction would be confirmed by the network. Users, developers and businesses (which at the time was pretty much the only real bitcoin subreddit) started to discuss how we should solve the problem bitcoin. There was significant support from the users and businesses behind a simple solution put forward by the developer Gavin Andreesen. Gavin was the lead developer after Satoshi Nakamoto left bitcoin and he left it in his hands. Gavin initially proposed a very simple solution of increasing the limit which was to change the few lines of code to increase the maximum number of transactions that are allowed. For most of bitcoin's history the transaction limit had been set far far higher than the number of transactions that could potentially happen on the network. The concept of increasing the limit one time was based on the fact that history had proven that no issue had been cause by this in the past. A certain group of bitcoin developers decided that increasing the limit by this amount was too much and that it was dangerous. They said that the increased use of resources that the network would use would create centralisation pressures which could destroy the network. The theory was that a miner of the network with more resources could publish many more transactions than a competing small miner could handle and therefore the network would tend towards few large miners rather than many small miners. The group of developers who supported this theory were all developers who worked for the company Blockstream. The argument from people in support of increasing the transaction capacity by this amount was that there are always inherent centralisation pressure with bitcoin mining. For example miners who can access the cheapest electricity will tend to succeed and that bigger miners will be able to find this cheaper electricity easier. Miners who have access to the most efficient computer chips will tend to succeed and that larger miners are more likely to be able to afford the development of them. The argument from Gavin and other who supported increasing the transaction capacity by this method are essentially there are economies of scale in mining and that these economies have far bigger centralisation pressures than increased resource cost for a larger number of transactions (up to the new limit proposed). For example, at the time the total size of the blockchain was around 50GB. Even for the cost of a 500GB SSD is only $150 and would last a number of years. This is in-comparison to the $100,000's in revenue per day a miner would be making. Various developers put forth various other proposals, including Gavin Andresen who put forth a more conservative increase that would then continue to increase over time inline with technological improvements. Some of the employees of blockstream also put forth some proposals, but all were so conservative, it would take bitcoin many decades before it could reach a scale of VISA. Even though there was significant support from the community behind Gavin's simple proposal of increasing the limit it was becoming clear certain members of the bitcoin community who were part of Blockstream were starting to become increasingly vitriolic and divisive. Gavin then teamed up with one of the other main bitcoin developers Mike Hearn and released a coded (i.e. working) version of the bitcoin software that would only activate if it was supported by a significant majority of the network. What happened next was where things really started to get weird. After this free and open source software was released, Theymos, the person who controls all the main communication channels for the bitcoin community implemented a new moderation policy that disallowed any discussion of this new software. Specifically, if people were to discuss this software, their comments would be deleted and ultimately they would be banned temporarily or permanently. This caused chaos within the community as there was very clear support for this software at the time and it seemed our best hope for finally solving the problem and moving on. Instead a censorship campaign was started. At first it 'all' they were doing was banning and removing discussions but after a while it turned into actively manipulating the discussion. For example, if a thread was created where there was positive sentiment for increasing the transaction capacity or being negative about the moderation policies or negative about the actions of certain bitcoin developers, the mods of bitcoin would selectively change the sorting order of threads to 'controversial' so that the most support opinions would be sorted to the bottom of the thread and the most vitriolic would be sorted to the top of the thread. This was initially very transparent as it was possible to see that the most downvoted comments were at the top and some of the most upvoted were at the bottom. So they then implemented hiding the voting scores next to the users name. This made impossible to work out the sentiment of the community and when combined with selectively setting the sorting order to controversial it was possible control what information users were seeing. Also, due to the very very large number of removed comments and users it was becoming obvious the scale of censorship going on. To hide this they implemented code in their CSS for the sub that completely hid comments that they had removed so that the censorship itself was hidden. Anyone in support of scaling bitcoin were removed from the main communication channels. Theymos even proudly announced that he didn't care if he had to remove 90% of the users. He also later acknowledged that he knew he had the ability to block support of this software using the control he had over the communication channels. While this was all going on, Blockstream and it's employees started lobbying the community by paying for conferences about scaling bitcoin, but with the very very strange rule that no decisions could be made and no complete solutions could be proposed. These conferences were likely strategically (and successfully) created to stunt support for the scaling software Gavin and Mike had released by forcing the community to take a "lets wait and see what comes from the conferences" kind of approach. Since no final solutions were allowed at these conferences, they only served to hinder and splinter the communities efforts to find a solution. As the software Gavin and Mike released called BitcoinXT gained support it started to be attacked. Users of the software were attack by DDOS. Employees of Blockstream were recommending attacks against the software, such as faking support for it, to only then drop support at the last moment to put the network in disarray. Blockstream employees were also publicly talking about suing Gavin and Mike from various different angles simply for releasing this open source software that no one was forced to run. In the end Mike Hearn decided to leave due to the way many members of the bitcoin community had treated him. This was due to the massive disinformation campaign against him on bitcoin. One of the many tactics that are used against anyone who does not support Blockstream and the bitcoin developers who work for them is that you will be targeted in a smear campaign. This has happened to a number of individuals and companies who showed support for scaling bitcoin. Theymos has threatened companies that he will ban any discussion of them on the communication channels he controls (i.e. all the main ones) for simply running software that he disagrees with (i.e. any software that scales bitcoin). As time passed, more and more proposals were offered, all against the backdrop of ever increasing censorship in the main bitcoin communication channels. It finally come down the smallest and most conservative solution. This solution was much smaller than even the employees of Blockstream had proposed months earlier. As usual there was enormous attacks from all sides and the most vocal opponents were the employees of Blockstream. These attacks still are ongoing today. As this software started to gain support, Blockstream organised more meetings, especially with the biggest bitcoin miners and made a pact with them. They promised that they would release code that would offer an on-chain scaling solution hardfork within about 4 months, but if the miners wanted this they would have to commit to running their software and only their software. The miners agreed and the ended up not running the most conservative proposal possible. This was in February last year. There is no hardfork proposal in sight from the people who agreed to this pact and bitcoin is still stuck with the exact same transaction limit it has had since the limit was put in place about 6 years ago. Gavin has also been publicly smeared by the developers at Blockstream and a plot was made against him to have him removed from the development team. Gavin has now been, for all intents an purposes, expelled from bitcoin development. This has meant that all control of bitcoin development is in the hands of the developers working at Blockstream. There is a new proposal that offers a market based approach to scaling bitcoin. This essentially lets the market decide. Of course, as usual there has been attacks against it, and verbal attacks from the employees of Blockstream. This has the biggest chance of gaining wide support and solving the problem for good. To give you an idea of Blockstream; It has hired most of the main and active bitcoin developers and is now synonymous with the "Core" bitcoin development team. They AFAIK no products at all. They have received around $75m in funding. Every single thing they do is supported by theymos. They have started implementing an entirely new economic system for bitcoin against the will of it's users and have blocked any and all attempts to scaling the network in line with the original vision. Although this comment is ridiculously long, it really only covers the tip of the iceberg. You could write a book on the last two years of bitcoin. The things that have been going on have been mind blowing. One last thing that I think is worth talking about is the u/bashco's claim of vote manipulation. The users that the video talks about have very very large numbers of downvotes mostly due to them having a very very high chance of being astroturfers. Around about the same time last year when Blockstream came active on the scene every single bitcoin troll disappeared, and I mean literally every single one. In the years before that there were a large number of active anti-bitcoin trolls. They even have an active sub buttcoin. Up until last year you could go down to the bottom of pretty much any thread in bitcoin and see many of the usual trolls who were heavily downvoted for saying something along the lines of "bitcoin is shit", "You guys and your tulips" etc. But suddenly last year they all disappeared. Instead a new type of bitcoin user appeared. Someone who said they were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did. They had the exact same tone as the trolls who had disappeared. Their way to talking to people was aggressive, they'd call people names, they had a relatively poor understanding of how bitcoin fundamentally worked. They were extremely argumentative. These users are the majority of the list of that video. When the 10's of thousands of users were censored and expelled from bitcoin they ended up congregating in btc. The strange thing was that the users listed in that video also moved over to btc and spend all day everyday posting troll-like comments and misinformation. Naturally they get heavily downvoted by the real users in btc. They spend their time constantly causing as much drama as possible. At every opportunity they scream about "censorship" in btc while they are happy about the censorship in bitcoin. These people are astroturfers. What someone somewhere worked out, is that all you have to do to take down a community is say that you are on their side. It is an astoundingly effective form of psychological attack.
A Little Background India, the second-most populous country in the world, has an uneasy alliance with Bitcoin. Despite the obvious resistance of the authorities, cryptocurrency has become increasingly well known. But to understand the overall picture, it is necessary to remember that the current population of the country is more than 1.3 billion and it has a GDP of $10.51 trillion. India has a large number of highly qualified technical staff and takes the second place with the number of Internet users in the world (even more than the United States). Meanwhile, the value of the Indian rupee fell nearly 40% since the start of 2018, but according to the World Bank, the country is the global leader in international money transfers. In 2014, capital flows to India averaged $70.4 billion through private transfers, which was about 3.7% of the country’s GDP. In this context, Bitcoin has every chance to find an extremely attractive market for itself. The main problem for residents of India is a simple and affordable way to convert the digital currency into rupees. … Bitcointalk Username: PRASAD555
The payouts are small but over time they add up to a good chunk, enough to challenge those who still believe that “there is no such thing as a free lunch.” The crypto industry has created many opportunities for individuals to realize their dreams of financial freedom, but it’s worth pointing out that, whatever you find out there, if it looks too good to be true probably is.
A faucet is usually a website or app that offers the user a small amount of crypto in exchange for performing a task. Most of the time the task required is completing a simple captcha, but it can also be watching an ad or playing minigames. A faucet makes money via the ads on its platform, and shares some of the revenue with its users in the form of cryptocurrency. There is a timer, however, you can’t reclaim money from the faucet every minute, and also a minimum withdrawal requirement, meaning that you will only be able to reclaim the free Ethereum to your wallet after a certain amount. Ethereum faucets won’t offer a huge flow of value but patiently, drop by drop, you can earn a sizable amount.
Put simply airdrops are giveaways, the definition of free money. So why would someone do something like that? Let’s imagine a new crypto project is looking to launch their own token and fund their operations through an initial coin offering (ICO) or another fund raising mechanism. One good way projects use to get the word out there and build a community is to giveaway a portion of their tokens in an airdrop. It is important to note that airdrops won’t earn you Ethereum directly. The good news is that the majority of tokens use the Ethereum blockchain (ERC-20) and can be kept in your ETH wallet and easily sold for some free Ethereum once listed on exchanges. There are various platforms out there where one can track the latest airdrops.
Bounty campaigns are a tool used by new crypto projects to help them get some initial traction and online buzz. The participants are required to do simple tasks such as leaving a like, comment, or sharing social media posts from a certain crypto project. The most used social media platforms are Facebook, Telegram, and Twitter and the rewards are proportional to how big of a following you have on these platforms. Other common tasks include translation work, creating your own blog post and/or video content, and signature campaigns on the Bitcointalk forum, where most recent bounties appear. Once the bounty campaign comes to a halt, the newly minted tokens are distributed throughout the participants of the bounty campaign. As most new tokens are ERC20 tokens, they can easily be exchanged for some free Ethereum once listed on exchanges
Work for Ethereum
Yes, I know what you are thinking. Is it free Ethereum if we still have to work for it? No, but the upside is that it can pay way better than the other alternatives listed. The diversity of jobs offered is the same as other freelancing platforms with the difference that the jobs are paid in cryptocurrency, in this case ether. If you have some skills in design, writing, or coding (just to name a few) it might be wise to take a look at cryptogrind or XBTFreelancer. Reaching out to crypto businesses directly may also do the trick, as some are always looking for talent to help them out. Even if most don’t reply or turn you down, companies are now more than ever seeking talent in the crypto and blockchain space, so keep trying.
Referral Links for Crypto Exchanges
This one is good for those out there with friends that are also crypto savvy. Various exchanges offer affiliate programs where you get paid out for inviting your friends and colleagues onto their platform. Exchanges like Coinbase offer a one time payment when a new person joins their platform while others like Cryptmixer, for example, gives its members an impressive 50% of the revenue from the new clients they bring in. You can also use their exchange to swap the Bitcoin you receive to Ether, making it a great way to earn ETH.
The Bottom Line
Some methods involve a lot of work, others don’t require much of anything. Some you need to already own Ethereum, while others allow you to start from zero (although the payout is considerably smaller). Crypto has made value accessible to anyone with an internet connection, so choose the one method that best fits your needs and skills and you will be carving out your own space in the cryptosphere, starting with some free Ethereum.
Have you heard about 'money remittance' concept? I'm sure you have used or at least heard someone talking about using WesternUnion or even USPS to send money to their loved ones across boundaries, typically from one country to another (i.e., from US to Mexico). Sending 'money' to someone is not different than sending 'value' --that's worth something elsewhere-- or giving away some asset to a different person so he/she can use it towards any end. This core concept was looked-into by Satoshi Nakamoto (who invented Bitcoin) in its first whitepaper. Nevertheless, Bitcoin has its own setbacks regarding power-cost efficiency and transaction confirmation times, although it solves the 'double-spending' dilemma, it results in a pretty inefficient means to send small (<100 USD) amounts of money. Other thing to take into consideration when evaluating a remittance platform is the regulation sandbox on both ends of the transaction. If the sender is in an over-regulated country, as is the recipient, then it could be costly and even unlawful, resulting on market inefficiencies that makes cryptocurrency remittances highly risky. Bitcoin Token (BTCT) is a PIVX fork who, itself, is a DASH fork who, itself, is a BTC fork. That makes BTCT a 4th. BTC generation crypto asset, classified as a payment coin with its own blockchain. BTCT confirms transactions in less than 3 seconds. BTCT uses 1/1000 of the power used by a BTC miner to create new coins and it has the same total supply as BTC, that is: 21 million coins. And BTCT is also a PoS protocol crypto asset, making it available to mine either by old computers as newly produced high-end ones, like any i7 or AMD Ryzen based motherboards. Bitcoin Token (BTCT) is also a true decentralised project, like BTC; there's no CEO nor CTO nor CFO, making it a community-driven cryptocurrency. Bitcoin Token (BTCT) was launched on 21st. November, 2019. It has a market capitalization of about 300K USD and its current price is ranging between 50 and 150 satoshis. Their community is 50K+ wide abroad Twitter, Telegram, Facebook, Instagram, Discord and Bitcointalk. The cost of one masternode (staking miner) is about $70 USD, which has an implicit collateral of 10K BTCT coins. They're listed on 6+ exchanges, CoinMarketCap, CoinGecko and have a really awesome dev team. There's been a lot of chatter about this project being able to deliver BTCT direct spending on 'real-fiat' world via a debit card, and that's because of their partnership with ZCore. If they manage to do that, I'm sure it will surely be a nice valuable alternative to remittance coins like XRP, and it would likely pose a very interesting investment option for 'low-marketcap' cryptos. Their official website is: https://www.bitcointoken.pw/
The next XVG? Microcap 100x potential actually supported by fundamentals!
What’s up team? I have a hot one for you. XVG returned 12 million percent in 2017 and this one reminds me a lot of it. Here’s why: Mimblewimble is like Blu-Ray compared to CD-ROM in terms of its ability to compress data on a blockchain. The current BTC chain is 277gb and its capacity is limited because every time you spend a coin, each node needs to validate its history back to when it was mined (this is how double spending is prevented). Mimblewimble is different - all transactions in a block are aggregated and netted out in one giant CoinJoin, and only the current spending needs to be verified. This means that dramatically more transactions can fit into a smaller space, increasing throughput and lowering fees while still retaining the full proof of work game theory of Bitcoin. These blockchains are small enough to run a full node on a cheap smartphone, which enhances the decentralization and censorship resistance of the network. The biggest benefit, though, is that all transactions are private - the blockchain doesn’t reveal amounts or addresses except to the actual wallet owner. Unlike earlier decoy-based approaches that bloat the chain and can still be data mined (XMR), Mimblewimble leaves no trace in the blockchain, instead storing only the present state of coin ownership. The first two Mimblewimble coins, Grin and Beam, launched to great fanfare in 2019, quickly reaching over $100m in market cap (since settled down to $22m and $26m respectively). They are good projects but grin has infinite supply and huge never-decreasing emission, and Beam is a corporate moneygrab whose founding investors are counting on you buying for their ROI. ZEC is valued at $568m today, despite the facts that only 1% of transactions are actually shielded, it has a trusted setup, and generating a confidential transaction takes ~60 seconds on a powerful PC. XMR is a great project but it’s valued at $1.2b (so no 100x) and it uses CryptoNote, which is 2014 tech that relies on a decoy-based approach that could be vulnerable to more powerful computers in the future. Mimblewimble is just a better way to approach privacy because there is simply no data recorded in the blockchain for companies to surveil. Privacy is not just for darknet markets, porn, money launderers and terrorists. In many countries it’s dangerous to be wealthy, and there are all kinds of problems with having your spending data be out there publicly and permanently for all to see. Namely, companies like Amazon are patenting approaches to identify people with their crypto addresses, “for law enforcement” but also so that, just like credit cards, your spending data can be used to target ads. (A) Coinbase is selling user data to the DEA, IRS, FBI, Secret Service, and who knows who else? (B) What about insurance companies raising your premiums or canceling your policy because they see you buying (legal) cannabis? If your business operates using transparent cryptocurrency, competitors can data mine your customer and supply chain data, and employees can see how much everyone else gets paid. I could go on, but the idea of “I have nothing to hide, so what do I care about privacy?” will increasingly ring hollow as people realize that this money printing will have to be paid by massive tax increases AND that those taxes will be directly debited from their “Central Bank Digital Currency” wallets. 100% privacy for all transactions also eliminates one HUGE problem that people aren’t aware of yet, but they will be: fungibility. Fungibility means that each coin is indistinguishable from any other, just like paper cash. Why is this important? Because of the ever-expanding reach of AML/KYC/KYT (Anti-Money Laundering / Know Your Customer / Know Your Transaction) as regulators cramp down on crypto and banks take over, increasingly coins become “tainted” in various ways. For example, if you withdraw coins to a mixing service like Wasabi or Samourai, you may find your account blocked. (C) The next obvious step is that if you receive coins that these chainalysis services don’t like for whatever reason, you will be completely innocent yet forced to prove that you didn’t know that the coins you bought were up to no good in a past life. 3 days ago, $100k of USDC was frozen. (D) Even smaller coins like LTC now have this problem, because “Chinese Drug Kingpins” used them. (E) I believe that censorable money that can be blocked/frozen isn’t really “your money”. Epic Cash is a 100% volunteer community project (like XVG and XMR) that had a fair launch in September last year with no ICO and no premine. There are very few projects like this, and it’s a key ingredient in Verge’s success (still at $110m market cap today despite being down 97% since the bubble peak) and why it’s still around. It has a small but super passionate community of “Freemen” who are united by a belief in the sound money economics of Bitcoin Standard emission (21m supply limit and ever-decreasing inflation) and the importance of privacy. I am super bullish on this coin for the following reasons:
Only $400k market cap
Supply started at zero, so there are no VC’s and team to dump on you into the pumps - all coins are mined into existence, just like Bitcoin.
It just had its first halving, reducing emission from 16 to 8 per block. Between now and 2028 there are FOUR (!) more halvings, from 4 to 2 to 1 and then finally 0.15 (I guess that would be an 85%-ing :p) and at this point the supply is the same as BTC and stays in sync forever until the last coin is mined in 2140. This simple supply curve is already accepted by the market as a winner, so why mess with success? (I)
Meets Andreas Antonopolous’ 5 pillars of open blockchains test: Public, Open, Borderless, Neutral, and Censorship Resistant. (How many coins can say this?)
Unlike Bitcoin, Epic created a multi-algorithm approach that enables people to mine on ordinary computers - 60% for CPU on RandomX, 38% for GPU on ProgPow, and 2% for ASIC’s on Cuckoo31+. The algorithms don’t compete with one another. This is essential for leveling the playing field and preventing massive farms from dominating. These percentages can change over time and new algorithms can be easily dropped in. You can mine today using an old laptop and in 5 years you will still be able to. Incidentally, there is nothing standing in the way of adding mobile phone-based mining, which ETN showed there’s a huge demand for.
Based off the excellent Grin codebase, which means they continue to pull in ongoing core code enhancements and focus on ease of use and market penetration instead. (Smart!)
Litecoin’s Charlie Lee is out there daily talking about their move to Mimblewimble, which provides free publicity. What people don’t realize is that you can’t just bolt on Mimblewimble to a legacy blockchain, that’s like putting a Ferrari engine into a school bus - it’s still a school bus, not a race car! LTC is doing it as an optional soft fork via “extension blocks” which will not be supported by all wallets and exchanges. Also, anyone using “optional” privacy features is declaring themselves to be suspicious, which kind of defeats the point for people who care about privacy.
The community is friendly and welcoming to new people coming in, with lots of helpful (independently created) tutorials and guides. (F)
It’s already a global phenomenon, with the whitepaper in 20+ languages (G) and (not bot-infested) active local-language communities on not only Telegram but also Wechat, LINE, QQ and other messenger platforms.
It’s only on two random little exchanges currently, Citex and Vitex. Vitex is actually a pretty good DEX with no KYC and a great mobile wallet.
They are very creative - since centralized exchanges want huge money to list, they created a non-inflationary ERC20 tracker token that’s exchangeable 1:1 for coins so that Uniswap trading is possible (H)
Because it doesn’t have a huge marketing budget in a sea of VC-funded shitcoins, it is as-yet undiscovered, which is why it’s so cheap. There are only 4 Mimblewimble-based currencies on the market: MWC at $162m, BEAM at $26m, GRIN at $22m, and EPIC at $0.4m. This is not financial advice and as always, do your own research, but I’ve been buying this gem for months and will continue to. This one ticks all the boxes for me, the only real problem is that it’s hard to buy much without causing a huge green candle. Alt season is coming, and coins like this are how your neighbor Chad got his Lambo back in 2017. For 2021, McLaren is a better choice and be sure to pay cash so that it doesn’t get repossessed like Chad!
By the end of December 2017, cryptoasset market cap breaks $600bn meanwhile the worldwide daily exchange volume has reached an astonishing $5 billion according to CoinMarketCap. Other than Bitcoin, new cryptocurrencies with new technologies and features have been emerging vigorously in recent years. And their total value and exchange volume has gone over 50% of the global market. Currently, the daily exchange volume of each worldwide top 10 platform has already reached $100 million and maintained the prosperous development. Based on the calculation of 0.1% commission, the daily income of a vibrant platform shall reach $100,000. Bitcointalk username - rajveerkamboj
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

Part 1/4 - NSA Connection: First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001. SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits. Moreover, all outputs appear completely random and offer no information about the input that created it. The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses. Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean? Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views. As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that. As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential. In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto. Part 2/4 - 'Crypto Market': Most of the crypto market is a scam. By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010: "if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin... Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way." To which Bitcoin OG Gavin Andresen replies: "I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles." "I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)." Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access). On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful. This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times. In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who: A) Think they can outsmart professional traders with actual risk management skills; and B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions. Part 3/4 - CBDCs: The Fed and Central Banks around the world have printed themselves into a corner. Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels. This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster. The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing. The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality. They, obviously, know this (as it is by design). The issue (for them) is that more and more people are starting to become aware of this. Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free. It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums. Now...back to the powers that be. Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state? More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system. This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment. Part 4/4 - Bitcoin: What about Bitcoin? Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World. But what about Bitcoin's reputation? Bankers hate it. Warren Buffett hates it. Precisely, and the public hates bankers. Sure, the investing public respects Buffett, but the general public perception of anyone worth $73 billion is not exactly at all time highs right now amid record wealth inequality. In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion. For example, the market cap of Gold is around $9 trillion, which is 50x the Market Cap of Bitcoin. Money has certain characteristics. In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation. Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation. One of the key strengths of Bitcoin is the fact that the Network is decentralised... Many people don't know that PayPal originally wanted to create a global currency similar to crypto. Overall, a speculative thesis would be the following: Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race. Trusted third parties are security holes. Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion. In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale. At the time, he was looking for signs of extraterrestrial life within cosmic signals. The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation. Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W); A Type 2 Civilisation has mastery over its solar system (10^26W); and a Type 3 Civilisation has mastery over its Galaxy (10^36W). We humans are a Type 0 Civilisation on this Scale. Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1. In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73. Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status. As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation. What are your thoughts? Is it true...or false? https://www.youtube.com/watch?v=1oQLOqpP1ZM
As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic. If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties, and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? ,, Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?
FIRST THERE WAS BITCOIN
Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash.  Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis. This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster. This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain. This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:
CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES
Used in: Monero and Particl as its successor RING-CT, Bytecoin In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy. An updated CryptoNote version 2 came in October 2013 (though there is some dispute over this timeline ), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed ), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014. RING SIGNATURES and STEALTH ADDRESSES
– Provides sender and receiver privacy – Privacy can be default – Mature technology – Greater scalability with bulletproofs – Does not require any third-party
– Privacy not very effective without high volume -Does not hide transaction information if not combined with another protocol.
Used in: Dash Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013)., CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular ,. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party. COINJOIN
– Provides sender and receiver privacy – Easy to implement on any cryptocurrency – Lightweight – Greater scalability with bulletproofs – Mature technology
– Least anonymous privacy solution. Transaction amounts can be calculated – Even without third-party mixer, depends on wealth centralization of masternodes
Used in: Zcoin, PIVX In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman. In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016.  ZEROCOIN
– Provides sender and receiver privacy – Supply can be audited – Relatively mature technology – Does not require a third-party
– Requires trusted setup (May not be required with Sigma protocol) – Large proof sizes (not lightweight) – Does not provide full privacy for transaction amounts
Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza). It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016.  ZEROCASH
– Provides full anonymity. Sender, receiver and amount hidden. – Privacy can be default? – Fast due to small proof sizes. – Payment amount can be optionally disclosed for auditing – Does not require any third-party
– Requires trusted setup. (May be improved with zt-starks technology) – Supply cannot be audited. And coins can potentially be forged without proper implementation. – Private transactions computationally intensive (improved with Sapling upgrade)
Used in: Monero and Particl with Ring Signatures as RING-CT The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer., It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable. CONFIDENTIAL TRANSACTIONS
– Hides transaction amounts – Privacy can be default – Mature technology – Does not require any third-party
– Only provides transaction amount privacy when used alone
Used in: Monero, Particl Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015. RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”. RingCT was implemented in Monero in January 2017 and made mandatory after September 2017. RING -CONFIDENTIAL TRANSACTIONS
– Provides full anonymity. Hides transaction amounts and receiver privacy – Privacy can be default – Mature technology – Greater scalability with bulletproofs – Does not require any third-party
– Privacy not very effective without high volume
Used in: Grin Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra., Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”. The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here . MIMBLEWIMBLE
– Hides transaction amounts and receiver privacy – Privacy is on by default – Lightweight – No public addresses?
– Privacy not very effective without high volume – Sender and receiver must both be online – Relatively new technology
Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation. It allows users of a decentralized ledger to “execute offline computations that result in transactions”, but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.
Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other. Its history dates back to 2003. Kovri is a Monero created implementation of I2P. The Onion Router (Tor) is another anonymity layer ) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.,,
Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero). Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required. There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.
PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS
Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

Bitcoin die-hard fans claim that this is never going to be an issue since Bitcoin was the pioneer and as such enjoys first-mover privilege. This argument is probably flawed because although the BTC is used for payments, this is only a relatively small % of all Bitcoins.
