Ritocoin - a 100% community driven project based on Ravencoin
tl:dr: Ritocoin is a code fork of the Ravencoin codebase and continues to track future Ravencoin developments. The project was launched to provide a more community-oriented blockchain with the same functionality as Ravencoin, without a corporate overseer, and with a more flexible model for community participation and development. It’s intention is to be a hacker’s playground for innovative ideas. Specifications Proof-of-Work Algorithm: X21S Block Time: 60 seconds POW Block Reward: Smooth curve down Community fund: 1% first year Difficulty Retargeting: DGW-180 Maximum Supply: 6 months: 993,521,892 RITO 1 year: 1,227,448,858 RITO 5 years: 1,762,210,058 RITO 10 years: 1,820,404,381 RITO 50 years: 2,030,907,256 RITO 100 years: 2,293,707,246 RITO Infinite: 10 RITO per block in perpetuity Pre-mine: None Masternodes: Researching for use case Asset layer: Was enabled at height 50,000 Links Website /ritocoin Explorer Github Whitepaper twitter [ANN] X21S This hashing algorithm was created specifically for Ritocoin, and was designed to resist FPGAs, ASICs, and NiceHash. It is X16S (16 algorithms shuffled and hashed),, followed by 5 additional hashing algorithms: haval256, tiger, lyra2, gost512, and sha256. The inclusion of lyra2 brings numerous advantages, making parallelization of the algorithm practically impossible, with each step relying on the previous step having already been computed. It is a “friendly” algorithm that makes GPUs produce much less heat and uses less electricity during mining. Take your time to learn more about us in the below story of Ritocoin... The spirit of Bitcoin continues to inspire, empower and enable people around the globe. Ten years later, just as it seemed Bitcoin was being defined by commercial agents and regulated governance, that same free and independent spirit imbued the Ravencoin community. In ten short months, however, 30% of the Ravencoin project’s net hash comes from NiceHash and the looming impact of the imminent FPGA mining cards and X16R bitstreams certainly promises to shake up the dream of this GPU miner’s darling. Ravencoin’s fair launch genuinely inspired our developers and supporters. We admire the way Ravencoin came out swinging — fighting for fairness, an honest distribution of coins and a place where GPU miners could thrive. The asset layer attracted many more miners and investors to the pools. Many Ritocoin enthusiasts came from the Ravencoin community, and continue their association with that project. The whole crypto ecosystem should appreciate the work begun by Ravencoin. Obviously they continue to inspire and motivate us to this day. It’s the reason we took action. We decided to start our own project which focuses upon at least two pillars of decentralized networks in the crypto space: community governance and a fair distribution of coins. It is a core belief throughout Ritocoin that in order to successfully develop and maintain this hacker’s playground — a place where a broad range of ideas could be tried and allowed to flourish — these two ideals must be allowed to drive and guide our community. This deep focus on community choices creates a project flexible enough to support most ideas, and agile enough to define new frontiers. A mining network’s distributed ledger is defined by its technology. Like many in the broader crypto-mining community, we value the GPU for its accessibility. These processors are available for purchase all around the world without any legal restrictions. GPUs are vastly more accessible for hobbyists and miners to acquire. They can be shipped nearly anywhere around the globe, a nice benefit to the popular secondary market which has sprung up much to the chagrin of PC gamers. More constraints exist for the ASIC and FPGA miner. Laws in some parts of the world restrict people from using or buying ASIC and FPGA mining hardware. This alone is directly in confrontation with Ritocoin’s core values of decentralized stewardship and sovereignty. The GPU, in essence, is like your voice. Anyone with the means of acquiring one GPU should be able to have their voice heard. ASIC and FPGA mining devalues the GPU miner’s voice and silos that coin’s network away from the small scale and personal mining operator. A truly community driven project means each stakeholder, regardless of size of contribution to the network’s net hash, has an opportunity to build, vote and direct. If you are already familiar with our website, discord or whitepaper, you are probably aware that masternodes had been proposed as a feature of the network from the beginning. This opened the door to ongoing discussions in the Ritocoin community regarding ● A masternode’s true purpose ● What benefit they provide to the project ● How the benefit is realized ● The collateral This discussion, governed entirely by stakeholders across the extended network yielded a defining moment for our vision of flexibility. We have not yet found the potential utility of masternodes, however, the conversation has not reached an extent to where we could abandon the idea. To quote one of our developers during this discussion on our Discord:
“Just want to give a reminder here that even though masternodes are on the roadmap, it is not set in stone. This coin belongs to the community and we will do what we as a community want to do. If we conclude that we want to take this coin a different direction than masternodes, then that is what we’ll do.” --traysi
We are all volunteers at Ritocoin. Our moderators and community leaders try to give immediate support to all users that require it. Contact us in Discord or Telegram, not only for support, but, proposing new ideas, revising old ones and just so you can find a place to get together and find people to hang out with. You are well within your rights to enjoy yourself at any given moment, and, should you feel so inclined to begin working with the team, we just so happen to be looking for ambitious individuals that see themselves as being part of a greater vision, are inspired by change, and inspired to be the change they want to see making things better in this world. Join us in a space where your ideas to build something great can become a reality. We are eager to know what you think is best for the future of Rito. What steps would you take to become more resilient, stronger, fair and decentralized? Because at the end of the day, like it or not, love it or leave it.. this is your coin, too. You can become a significant part of this project. We will help you further develop the role you wish to fill in the cryptocurrency space — influencer, developer, analyst, you name it. This is not a just-for-developer’s playground. We want the enthusiasts. We want the perplexed and the rabbit-hole divers. This is the coin for everyone who is trying to find their place on the path that Satoshi began unfolding in 2008 after the collapse of the housing market rippled out into the subsequent crash of global markets. That’s why we have Bitcoin, remember? Be your own bank. This is why Satoshi and Bitcoin.org kept their software open source. It’s up to us to keep the torch ablaze. Community funds For the first year, about 1% of mined coins are set aside into a developers fund that is used to provide bounties to the community developers who make substantial development contributions to the Ritocoin ecosystem. We have already paid out numerous bounties for important work that has already benefits Ritocoin in substantial ways. We also have another donation-driven community fund that has recently been put together for the purposes of doing fun contests and things like that. Cooperation and collaborations We have discovered a number of fatal flaws in the original Ravencoin codebase and worked with the Ravencoin developers to get those fixed in both Ritocoin and Ravencoin. This work has benefitted Ravencoin in numerous ways and we look forward to a long time of collaboration and cooperation between us and them. Many members of the Safecoin team are also in our discord group, and have collaborated with us in shaping the future decisions of Ritocoin. We have several thousand members in our group and they represent all walks of cryptocurrency life. We invite all coin developers, miners and enthusiasts to join our discord and be a part of this coin that truly belongs entirely to the community. Block reward A couple weeks ago we met for a scheduled meeting in our discord group and had a lengthy conversation about the block reward. Our block reward started at 5,000 RITO per block (every 60 seconds) just like Ravencoin. This extremely high number of coins coupled with the high profitability of mining led to unforeseen consequences with pools auto-exchanging the coin into bitcoin. This dumping by non-community miners had a very negative impact on the community sentiment and morale, as we watched the exchange price plunge. We looked at other coins and realized that this fate has befell many other coins with high block rewards. Following much discussion, we decided to change the reward structure. Starting around March 19th the block rewards will start to slowly go down in a curve until it reaches 1,000. Then the reduction will be even more slowed down with block rewards exponentially dropping at periodic intervals. We have posted charts on our website that shows what the long-term effects of our reward reducing algorithms will be. As a miner, the next 2 months will be a great time to mine and hold, while the block reward is still fairly high. We encourage all miners and cryptocurrency enthusiasts to take advantage of the current favourable block reward and build a nice holding for yourself. Then join the community and be a part of the fun we’re having with this project. This post was prepared by a collaboration of multiple Ritocoin members and was posted to reddit by the core developer Trevali, who posts to reddit under the ritocoin username and will be very happy to answer any questions anybody may have about our project. Traysi (well known in the Ravencoin community) is also an active Ritocoin developer and may come to this thread if needed. We welcome any questions from any of you regarding our project!
QuarkChain Testnet 1.0 was built based on standardized blockchain system requirements, which included network, wallet, browser, and virtual machine functionalities. Other than the fact that the token was a test currency, the environment was completely compatible with the main network. By enhancing the communication efficiency and security of the network, Testnet 2.0 further improves the openness of the network. In addition, Testnet 2.0 will allow community members (other than citizens or residents of the United States) to contribute directly to the network, i.e. running a full node and mining, and receive testnet tokens as rewards. QuarkChain Testnet 2.0 will support multiple mining algorithms, including two typical algorithms: Ethash and Double SHA256, as well as QuarkChain’s unique algorithm called Qkchash – a customized ASIC-resistant, CPU mining algorithm, exclusively developed by QuarkChain. Mining is available both on the root chain and on shards due to QuarkChain’s two-layered blockchain structure. Miners can flexibly choose to mine on the root chain with higher computing power requirements or on shards based on their own computing power levels. Our Goal By allowing community members to participate in mining on Testnet 2.0, our goal is to enhance QuarkChain’s community consensus, encourage community members to participate in testing and building the QuarkChain network, and gain first-hand experience of QuarkChain’s high flexibility and usability. During this time, we hope that the community can develop a better understanding about our mining algorithms, sharding technologies, and governance structures, etc. Furthermore, this will be a more thorough challenge to QuarkChain’s design before the launch of mainnet! Thus, we sincerely invite you to join the Testnet 2.0 mining event and build QuarkChain’s infrastructure together! Today, we’re pleased to announce that we are officially providing the CPU mining demo to the public (other than citizens and residents of the United States)! Everyone can participate in our mining event, and earn tQKC, which can be exchanged to real rewards by non-U.S. persons after the launch of our mainnet. Also, we expect to upgrade our testnet over time, and expect to allow GPU mining for Ethash, and ASIC mining for Double SHA256 in the future. In addition, in the near future, a mining pool that is compatible with all mining algorithms of QuarkChain is also expected to be supported. We hope all the community members can join in with us, and work together to complete this milestone! 2 Introduction to Mining Algorithms 2.1 What is mining？ Mining is the process of generating the new blocks, in which the records of current transactions are added to the record of past transactions. Miners use software that contribute their mining power to participate in the maintenance of a blockchain. In return, they obtain a certain amount of QKC per block, which is called coinbase reward. Like many other blockchain technologies, QuarkChain adopts the most widely used Proof of Work (PoW) consensus algorithm to secure the network. A cryptographically-secure PoW is a costly and time-consuming process which is difficult to solve due to computation-intensity or memory intensity but easy for others to verify. For a block to be valid it must satisfy certain requirements and hash to a value less than the current target threshold. Reverting a block requires recreating all successor blocks and redoing the work they contain, which is costly. By running a cluster, everyone can become a miner and participate in the mining process. The mining rewards are proportional to the number of blocks mined by each individual. 2.2 Introduction to QuarkChain Algorithms and Mining setup According to QuarkChain’s two-layered blockchain structure and Boson consensus, different shards can apply different consensus and mining algorithms. As part of the Boson consensus, each shard can adjust the difficulty dynamically to increase or decrease the hash power of each shard chain. In order to fully test QuarkChain testnet 2.0, we adopt three different types of mining algorithms” Ethash, Double SHA256, and Qkchash, which is ASIC resistant and exclusively developed by QuarkChain founder Qi Zhou. These first two hash algorithms correspond to the mining algorithms dominantly conducted on the graphics processing unit (GPU) and application-specific integrated circuits (ASIC), respectively. I. Ethash Ethash is the PoW mining algorithm for Ethereum. It is the latest version of earlier Dagger-Hashimoto. Ethash is memory intensive, which makes it require large amounts of memory space in the process of mining. The efficiency of mining is basically independent of the CPU, but directly related to memory size and bandwidth. Therefore, by design, building Ethash ASIC is relatively difficult. Currently, the Ethash mining is dominantly conducted on the GPU machines. Read more about Ethash: https://github.com/ethereum/wiki/wiki/Ethash II. Double SHA256 Double SHA256 is the PoW mining algorithms for Bitcoin. It is computational intensive hash algorithm, which uses two SHA256 iterations for the block header. If the hash result is less than the specific target, the mining is successful. ASIC machine has been developed by Bitmain to find more hashes with less electrical power usage. Read more about Double SHA256: https://en.bitcoin.it/wiki/Block_hashing_algorithm III. Qkchash Originally, Bitcoin mining was conducted on the CPU of individual computers, with more cores and greater speed resulting in more profitability. After that, the mining process became dominated by GPU machines, then field-programmable gate arrays (FPGA) and finally ASIC, in a race to achieve more hash rates with less electrical power usage. Due to this arms race, it has become increasingly harder for prospective new miners to join. This raises centralization concerns because the manufacturers of the high-performance ASIC are concentrated in a small few. To solve this, after extensive research and development, QuarkChain founder Dr. Qi Zhou has developed mining algorithm — Qkchash, that is expected to be ASIC-resistant. The idea is motivated by the famous date structure orders-statistic tree. Based on this data structure, Qkchash requires to perform multiple search, insert, and delete operations in the tree, which tries to break the ASIC pipeline and makes the code execution path to be data-dependent and unpredictable besides random memory-access patterns. Thus, the mining efficiency is closely related to the CPU, which ensures the security of Boston consensus and encourges the mining decentralization. Please refer to Dr. Qi’s paper for more details: https://medium.com/quarkchain-official/order-statistics-based-hash-algorithm-e40f108563c4 2.3 Testnet 2.0 mining configuration Numbers of Shards: 8 Cluster: According to the real-time online mining node The corresponding mining algorithm is Read more about Ethash with Guardian: https://github.com/QuarkChain/pyquarkchain/wiki/Ethash-with-Guardian) We will provide cluster software and the demo implementation of CPU mining to the public. Miners are able to arbitrarily select one shard or multiple shards to mine according to the mining difficulty and rewards of different shards. GPU / ASIC mining is allowed if the public manages to get it working with the current testnet. With the upgrade of our testnet, we will further provide the corresponding GPU / ASIC software. QuarkChain’s two-layered blockchain structure, new P2P mode, and Boson consensus algorithm are expected tobe fully tested and verified in the QuarkChain testnet 2.0. 3 Mining Guidance In order to encourage all community members to participate in QuarkChain Testnet 2.0 mining event, we have prepared three mining guidances for community members of different backgrounds. Today we are releasing the Docker Mining Tutorial first. This tutorial provides a command line configuration guide for developers and a docker image for multiple platforms, including a concise introduction of nodes and mining settings. Follow the instructions here: Quick Start with QuarkChain Mining. Next we will continue to release: A tutorial for community members who don’t have programming background. In this tutorial, we will teach how to create private QuarkChain nodes using AWS, and how to mine QKC step by step. This tutorial is expected to be released in the next few days. Programs and APIs integrated with GPU / ASIC mining. This is expected to allow existing miners to switch to QKC mining more seamlessly. Frequently Asked Questions: 1. Can I use my laptop or personal computer to mine? Yes, we will provide cluster software and the demo implementation of CPU mining to the public. Miners will be able to arbitrarily select one shard or multiple shards to mine according to the work difficulty and rewards of different shards. 2. What is the minimum requirements for my laptop or personal computer to mine? Please prepare a Linux or MacOs machine with public IP address or port forwarding set up. 3. Can I mine with my GPU or an ASIC machine? For now, we will only be providing the demo implementation of CPU mining as our first step. Interested miners/developers can rewrite the corresponding GPU / ASIC mining program, according to the JSON RPC API we provided. With the upgrade of our testnet, we expect to provide the corresponding GPU / ASIC interface at a later date. 4. What is the difference among the different mining algorithms? Which one should I choose? Double SHA256 is a computational intensive algorithm, but Ethash and Qkchash are memory intensive algorithms, which have certain requirements on the computer’s memory. Since currently we only support CPU mining, the mining efficiency entirely depends on the cores and speed of CPU. 5. For testnet mining, what else should I know? First, the mining process will occupy a computer’s memory. Thus, it is recommended to use an idle computer for mining. In Testnet 2.0 settings, the target block time of root chain is 60 seconds, and the target block time of shard chain is 10 seconds. The mining is a completely random process, which will take some time and consume a certain amount of electricity. 6. What are the risks of testnet mining? Currently our testnet is still under the development stage and may not be 100% stable. Thus, there would be some risks for QuarkChain main chain forks in testnet, software upgrades and system reboots. These may cause your tQKC or block record to be lost despite our best efforts to ensure the stability and security of the testnet.

The $22,484.00 Butterfly Labs Mini Rig bitcoin miner is a huge, broken, unstable piece of shit.
(This was a rather controversial article posted on Buttcoin.org and became quite popular, even moving to the top of /bitcoin. It's since been mysteriously edited on the site [maybe by g-g-g-ghosts!] so it's being reposted here for posterity's sake. Some numbers may be off by now, but it was all accurate at the time of posting.) Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5. So what does $22,484 buy you? Take a look!
Minirig is here! Today, my Minirig arrived. http://i.imgur.com/Yp0WPvE.jpg FedEx apparently dropped it somewhere along the way, and the weakest part of the case, the thin metal part around the back of the PSU, broke. http://i.imgur.com/lFcOHxP.jpg I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either. http://i.imgur.com/AVttcOt.jpg The power supplies (EVGA 1500W) also created havoc interfering with the neutral on the power line. This disrupted X10 communication significantly enough that the pool overflowed because the system controlling it was unable to turn off the pump. Workaround: This PSU supports 240V, so we rewired the outlet. 240V does not use neutral, so now all should be okay. Edit: 240V workaround is only partial. Still having problems But the good news is, it all seems to be working for the most part. Next up, installing it in the window so the heat goes outside
A twenty two thousand dollar box of electronics that is broken out of the box, that required the guy to do a sketchy electrical workaround to get partially working, that he is going to install in a window… and he’s happy about it? In case you didn’t notice it, the delivered unit is different than the picture on the website. They had to install 2 power supplies instead of 1 and had to modify the case to fit. Also, if you didn’t notice, the LCD/Phone thingy in the front has been replaced by … a piece of cardboard spray painted black. Wonderful. You could maybe chalk this up to a careless Fedex postman, but when you’re shipping something that costs as much as a mid-sized sedan, how bought putting a little more effort into packing? Dell and HP can ship bigger and heavier servers across the world without this kind of problem. The unit had to hit its huge power draw increase by putting dual EVGA consumer grade power supplies in the unit. We’re talking almost a 75 amp load (6*1500/120), disregarding power factor. He could very well overload the circuit panel and trip the main breaker for the house. Let’s take a look inside this guy. This is from an earlier version of the Minirig (note the single power supply) This is apparently from an earlier FPGA but it will give you a good glimpse at what kind of craftsmanship you can expect from a computer that is half the average household income in the United States. Consumer grade PSU and cheap USB hubs glued to the inside case. Electrical tape and random velcro glued to the insides A closer look at the USB hubs. Plugs are hot glued to stay secured. Electrical tape everywhere, splices and voided hardware are the theme. You can view the entire album here. Despite all that, this thing can still mine bitcoins and it should be profitable. Keep in ind that many people jumped in on the preorders a year ago when bitcoins were still hovering around $6.50 per. Meaning customers paid 1562 bitcoins for that particular piece of shit, which at today’s value is $156,200. Aston martin money. How long will it take them to make their money back (as apposed to just hanging on to them)? If the difficulty didn’t change, they would make 37 bitcoins a day and recoup the initial investment in 124 days. Difficulty is jumping pretty much 20% every 12 days or so, so in the next week before adjustment, they’ll make 259, the next 12 days 369, the next 12 days 312, then 256, then 213, etc. So by day 127, they’ll be halfway to breaking even, but by day 151 they’ll be making less than 5 bitcoins a day, and even if difficulty stopped rising at that point(which it won’t), it would take another 435 days for a total of 586 days to break even. If difficulty kept rising at the same pace, by day 200 they’d be making 2.4 bitcoins per day, and it would take 1024 days to break even with no difficulty increase. Assuming 25 cents per kw/h, and $100 a bitcoin, it would cost 0.43 of a bitcoin per day in electricity which means the unit would no longer be profitable on a power usage basis by day 307, at which point it will have produced 2620 bitcoins. Bear in mind this is only for the first few units, and that’s running 24/7 pumping out around 24,000 BTU, so yes, medical bills from heat stroke will be on top of that. But Alas, the chips don’t run nearly as well as they’re supposed to, frequently running too hot and giving multiple hardware failures. Coindesk noted in one of the first ever runs of the Minirig by hosting provide gigavps that it was running much too hot and erroring out.
At the time of posting, gigavps warned that the unit would be repeatedly shut down while ckolivas, who was assisting, modified the machine’s software to optimise performance. After some tweaking, the device was said to have been left to run continuously for two hours, and was shown to have an average hash rate of 478.1 GH/s. As you can see in the table below, ASIC number four (of a total of eight hashing chips) ran significantly hotter (86 degrees) and consequently gave the highest hardware (HW) error rate. http://i.imgur.com/q3iGrnb.jpg
So, what happens if you just decide you don’t want this, you don’t want to wait over a year to get a $22,000 broken piece of shit? Nothing, because BFL won’t let you cancel your preorder because they’re now “shipping”, i.e. they sent out one unit to their own company shill. http://i.imgur.com/0p3Up03.jpg Which is of course illegal regardless of what Butterfly Labs may say. So in summary: Don’t buy anything from Butterfly Labs … ever.
_trendspotter at /goodcoin brought up an evaluation we can use to at least measure, rate, or review cryptocurrency based on how good they are. Here at scamcoin I think we should come up the evaluation on how BAD these guys are, just the opposite of his scale. I suggest you should use this guide also as a reference when you are looking to INVEST in a cryptocurrency. If you guys have suggestions/ideas feel free to bring it up. It is no way being objective but at least we can try. Power to the people. The problem I still trying to sort out is to weight some features properly: Anyway, the proposal Scammy Scale Rating with simple Yes or No: 1) NOT de-centralize & Not open source 2) No open-source at the release 3) "Public offering" period where one has to pay to mine early 4) No fair launch announcement, unreasonable pre-mine and/or any insta-mine 5) Extremely low starting difficulty 6) No adoption among merchants/vendors/region/country. 7) No trading at big exchanges (e.g. not on BTC-e) 8) Not offer any new feature. Clonecoins or Litecoin forking 9) Bad developer supports, lack of community or forum 10) Releasing bad software that impedes certain users from using/mining the coin. Or "faulty" start, "nodes" problem 11) Slow transaction or confirmation time 12) Short block time when mining 13) Inflated to billion of shares/coins or unreasonable supplies 14) Pseudo mumbo jumbo descriptions of the cryptocurrency 15) Poor official website, hastily done 16) No anonymity support (no Zerocoin implementation) 17) Weak security, vulnerable to 51% attack (No POS or Proof of Stake) 18) Aggressive marketing campaign, hijacking forums and threads, tons of giveaways and faucets 19) Bloat future blockchain, e.g. 2GB-60-100GB wallet you have to update even though your wallet has 2 ABC coin. 20) Weak to ASIC,GPU,FPGA miners, BotNet, or does not give everyone at least a fair chance to mine 21) Reversible transaction -- Not sure if I should leave this out 22) Low mining profitability (vs mining Bitcoin) 23) Designed to be inflationary nature 24) No interest rate of earning coin per year 25) No Multi-hashing algorithms 26) Recent release 27) Pump and dump announcements (Twitter, Facebook, subreddits or forums) associated with said cryptocurrency 28) "Rebooting" the coin, or "coin makeover" to make it fair mining/distribution again 29) Shady developers' history and/or shady major fund backers' history/intention 30) No trendsetter or no noise around the web. Use Google Trend as a way to monitor buzzes. Example:http://www.google.com/trends/explore#q=quark%20coin%2C%20bitcoin&cmpt=q 31) Not much liquidity and being dependent. How dependent of that alt-coin to that of Bitcoin? Meaning, if Bitcoin goes down 20% in value, will it also dip 20% or more? 32) Unknown or less coins' volume/share percentage jumped through the roof while other known coins have modest or small gain. Example: SexCoin jumped 1200% in a single day while Bitcoin gained 3.8% 33) "Pay first, deliver product [Bitcoin 2.0] later" - essentially investors are convinced they have to pay first in USD/bitcoin because they are promised by the developers/company to have an "EARLY START" or "EARLY SHARES" or "PRE-SHARES" on the best next-generation "Bitcoin 2.0" coin that will make Bitcoin obsolete and will be the next biggest thing in the universe. Except for the part where "the biggest thing in the universe" is nowhere to be seen. 34) Interoperability 35) Purely Proof-of-Stake (POS) coins We then can further breakdown and give weigh point to each feature and start ranking them. For example: CrappyCoin : 10 yes, 15 No. A simple solution is each Yes = 1 point and each No = 0 point. However, subjectively some features should be weight more than others. I should point how to merchant adoption and trading/buy/sell at big exchanges, multi-hashing and fair mining for everyone should be scored higher. It goes hand-in-hand with its release date. Feel free to discuss.
