Bitcoin (BTC) may score a new all-time high in 2021, but the odds are that it won’t happen next month.

Historical price data confirms that September tends to see BTC price losses — and its best-ever returns are still single figures.

September 2021 looks like a classic for BTC

As Bitcoin matures, it becomes more noticeable that BTC/USD behaves in similar ways during the same month each year.

Q4 is the clear standout for top performance, especially in the year following a block subsidy halving. By contrast, January tends to be bearish — although this year was a conspicuous exception to the rule.

Turning to September, however, and the picture is uninspiring for investors. Summer may be over, but historically, next month has never seen Bitcoin increase by more than 6%.

“Bitcoin doesn’t like September at all,” Cointelegraph contributor Michaël van de Poppe commented this week.

“Are we going to repeat and have a corrective month across markets, before the continuation of bull cycle?”Better luck in Q4?

September is already tipped to deliver a slightly lower price zone than August, something that PlanB, creator of the stock-to-flow Bitcoin price models, said is merely a data technicality.

Bitcoiners may not need to grin and bear it for long, however, as October tends to deliver much more convincing momentum.

Yet for the meantime, it seems that a retest of all-time highs will need to wait. At the time of writing, BTC/USD traded at $47,600, having lost around 1.6% in the past 24 hours.

The blockchain of Grin, a privacy centered crypto created on the Mimblewimble covenant, was subject to a 51% attack. As per a tweet by crypto miner 2Miners, an anonymous group amassed 57.4% of the aggregate hash power of the Grin (GRIN) network on Saturday.

While 2Miners stands second in the list with a control over 19.1% of GRIN’s hash power, sparkpool miners took the next place with a control over 18.9% of hash power.

Data provided by GrinScan indicates that hackers had succeeded in reorganizing a minimum of one forked block at 23:17 UTC on November 7. The anonymous mining group has also tightened its grip on Saturday by gaining control over 58.1% of GRIN’s hash rate. Other prominent miners include 2Miners’ which controls over 24.6% of the network, while that of sparkpool miners has declined to 11.3%.

The organization of blocks can be severely affected when a team of miners begin controlling over 50% of hash power or network’s mining power. This would cause the native token’s price volatility to increase considerably and shatter trust in the blockchain.

It should be noted that a mining group cannot be stamped as shyster just because it controls over 51% of hash power. For example, sparkpool had control of GRIN network’s 60% hashpower but did not disrupt the creation of fresh GRIN blocks.

The GRIN token continue to trade in a stable manner, despite the negative news, declining only 1.3% in the last 24 hours. Back in August, the Ethereum Classic (ETC) blockchain faced a minimum of three 51% attacks, resulting in the reorganization of thousands of blocks.

In contrast to the ETC blockchain attack, which would cost over $7,000 per hour for hackers to retain control of over 50% of blockchain’s hash power, maintaining a 51% control over GRIN blockchain will only cost $75 for hackers, making it an easy target, as per crypto tech data provider Crypto51.

We Give you an idea to overcome the day to day activities in your lifeGrin coin is privacy focused cryptocurrency that is aiming to offer the community a product based on ideas and technology rather than hype and ICO marketing. The Mimblewimble blockchain is being utilized by Grin developers to ensure a leave of privacy and scalability they claim has not yet been offered. The whimsical name is inspired by Harry Potter and its wizarding Gringotts Bank. To maintain a level of transparency and show the community that they are truly building something of value, the project is totally driven by donations. The developers are putting their extra time into Grin without the support of a foundation or barrels of money rolling in and shares a true sense of purity with the original cryptocurrency, Bitcoin. The projects’ founder, like Satoshi Nakamoto, has remained anonymous. He goes by the name ‘Igno Peverell’, and his goal is to build something that is valuable, community-based and open source without crossing over to the overhyped “buy my coin” section of the space. The anonymous Peverell spoke to cryptobriefing via email and shared his thoughts on Grin’s adoption. “We try to keep developing Grin and make it a great project and great community and to not worry too much about externalities and [things] we don’t really have control over.” Grin has been listed on 2 popular exchanges already. After being listed at Bittrex and Poloniex, Grin is showing to have some real value and staying power. This is usually viewed as a culminating and rewarding step for crypto startups, But Peverell is still more focused on viable usage and a strong community of adopters. “Personally, I don’t find them important at all. It’s early days. It’s nice with validation, but we have a lot of work to do. That’s the beauty with a project team that doesn’t have interests aligned with price movements – we work to advance the community and ecosystem, not to make the price go up and down.” This project should excite fans of decentralization and those who believe the development of useful technology is much more important than the rollercoaster markets. Poloniex released a statement that echoed this sentiment when they decided to list Grin. “We believe in supporting crypto projects which encourage distributed, voluntary development and fair, decentralized methods of token distribution. ” Regardless of price, projects with their minds set on building should be applauded as they attempt to realize the potential of the blockchain.The post Grin Coin (GRIN) is Growing on Work not Hype appeared first on ZyCrypto.

The Company Set to Partner on the Samsung S10Cryptocurrency: The Consumer Revolution. Use Mithril (MITH) to Get Tickets for Ed Sheeran Concert in TaiwanVeChain Announce 2019 Summit: BMW, DNV GL and Ocean Ex to ParticipateGrin has been doing things differently. From its privacy basis to its community driven approach to the running of the business, the token on the Mimblewimble project alongside Beam, have got a lot of rightful attention.What is clear is that Grin does not go with the status quo and this is seen no more so than the path taken with regards to mining. Grin, unlike Bitcoin and other major coins can be mined at your personal computer not on large ASIC mining machines. All you need to do is create a mining machine equipped with NVIDIA 1080Ti graphics card and you could dig an average of 1 per day when the main network of Grin was on the line. Grin in terms of mining is actually fairly complexed. Currently, Grin has two proof of work (PoW) algorithms which are designed to be memory latency-bound and not compute-bound like the SHA256 hash function used to mine Bitcoin. According to cryptoglobe, “There are two initial “Cuckoo Cycle” PoW algorithms used by Grin. One has been designated “AR” or ASIC-Resistant, the other “AF” or ASIC-Friendly. The confusion in Grin mining lies in the fact that both can be mined on GPUs right now – and only GPUs, the ASICs haven’t been manufactured yet.”With Ethereum, which was once the coin for graphics card owners, now having rather sidelined these lower level miners following the Ethereum Constantinople update, Grin it seems has taken the mantle as the go-to token for those unable to compete with the changes.1/ $ETH mining operational breakeven, paying $0.06 $/kWh for electricity, currently stands around $67 (estimates depend on operational costs other than electricity). For those buying 2nd hand RX580 GPUs and depreciating them in 1 year, breakeven after depreciation stands at $165According to Shen Yu, F2 Pool founder, Grin has a lot to offer NVIDIA miners:“The daily output is hundreds of thousands of dollars, almost one-fifth to one-fourth of the output of the Ethereum. Therefore, the miners are highly motivated, especially the N-card miners.”Although they may not have the price to match Ethereum, the partnership with Cudo is opening themselves up. Asia Crypto Today reported on the story previously, after Cudo Miner launched its GUI mining software for Grin, which it says will bring Grin mining “to the masses.” In the future they look set for the ASIC mining route too though. A Chinese company from Hangzhou, called VIDTOO, announced on Twitter that its Grin ASIC mining project has started pre-sales and will be available as early as this summer. The mine is more than 50 times more powerful than current GPU mines. The energy consumption is low, and the electricity bill only accounts for 1% of the mining business income.8BTC interviewed VIDTOO CEO Thomas. According to him, VIDTOO will release detailed mine specification data in April, and will be listed as early as June. “There is no public offering yet, and it will be based on market conditions. Determining the official release time and price will undoubtedly be the fastest and most cost-effective ASIC miner on the market.” Thomas said, “G1 will bring significant user growth to Grin, and the growth of computing power will benefit in the long run. The healthy and sustainable development of the currency price.”Currently, the daily production of Grin has reached 20% to 25% of Ethereum and that is without the huge mining companies like Bitmain or others attempting to use their ASIC mining machines. Now with the ASIC being used for Grin, alongside the NVIDIA supported way, it could propel the company forward. Tokengazer CEO, Fan Hongda, sees Grin breaking into the top 40 and become a profitable coin to mine by the end of the year. Perhaps Grin could be the rising star of 2019.

Imagine if you had the ability to go back in time and become one of the first people in the world to mine an experimental piece of technology called Bitcoin. Would you do it? Well, you might potentially have your shot with Grin (GRIN) coin.Lately, Grin has been generating a lot of excitement in the crypto community and it, along with MimbleWimble, might signal the revival of GPU mining. It has been in the works since late 2016 and it is a fully donations-based project that was launched fairly. It is not an ICO, it is not pre-mined and it doesn’t have founders rewards. In a lot of.investors’ minds it kind of pattern-matches to a bitcoin 2.0In short – Grin is a privacy coin that uses the MimbleWimble blockchain protocol. A  coin with no amounts, no addresses, and it scales by leveraging cryptography to allow most of its past transaction data to be removed.The Hong Kong-based cryptocurrency exchange has just listed Grin (GRIN) and it is now available to buy and sell. Supported trading pairs include GRIN/BTC, GRIN/ETH and GRIN/USDT.We can only speculate on what comes next, but if Grin follows a path to other mineable cryptocurrencies such as Ravencoin we could see a Binance listing earlier rather than later.However, it should be noted that Grin has its own downsides. It is highly inflationary, especially in its early years. There is literally one Grin coin mined every second. It’s actually a block per minute containing 60 coins. There will be no adjustments to the supply, no maximum cap, nor will there be any deflationary halving events to look forward to. In a sense, Grin is designed to be a private digital currency not a deflationary store of value.Grin’s emission is interesting, to say the least. With an infinite amount of coins and a linear supply schedule, it will mean that it will remain under extreme amounts of sell pressure in its early days. The initial surge spiked the coin’s value to as much as $261, which was quickly brought down to the ground by crypto miners. At the time of this writing, you can buy Grin (GRIN) at a 97% discount via Kucoin, currently trading at $4.40.Right now, Grin seems to be following a similar pattern to Ravencoin. Another mineable cryptocurrency with huger initial inflation that managed to break out of its slump with a vengeance as well as eventually being listed on Binance. It’s logical to assume that Grin (GRIN) could follow a very similar path as well.As far as mining is concerned there is still an opportunity for first-movers to take advantage of the high rewards from early mining. Just as long as you have the right hardware of course. If you’re not in a position to mine coin you can still pick up some Grin (GRIN) at a relatively cheap price via an exchange.Overall, if you’re looking for a get rich quick altcoin then Grin (GRIN) is probably not for you. Grin was launched on Jan. 15th 2019. It’s still a very young and experimental implementation of blockchain technology but so was bitcoin at one time. If you feel confident a 97% is as good of an opportunity to pick up a few Grin (GRIN) at Kucoin.It might not be Bitcoin, but it just might pay off in the long run.MINEABLE.com is your one-stop source for exclusive cryptocurrency news & innovations in Bitcoin mining.

MimbleWimble is a blockchain format and protocol that provides extremely good scalability, privacy and fungibility by relying on strong cryptographic primitives. It addresses gaps existing in almost all current blockchain imble/grinGrin is an open source software project that implements a MimbleWimble blockchain and fills the gaps required for a full blockchain and cryptocurrency deployment.The main goal and characteristics of the Grin project are:* Privacy by default. This enables complete fungibility without precluding the ability to selectively disclose information as needed.* Scales modestly with the number of transactions, keeping only a ~100 byte `kernel' for historical transactions, resulting in a large space savings compared to other blockchains.* Strong and proven cryptography. MimbleWimble only relies on Elliptic Curve Cryptography which has been tried and tested for decades.* Design simplicity that makes it easy to audit and maintain over time.* Community driven, using an asic-resistant mining algorithm (Cuckoo Cycle) encouraging mining decentralization.Приглашённые спикеры: - @ignopeverell (https://github.com/ignopeverell) основатель проекта Grin (синтезированный голос через ssh) - @hashmap (https://github.com/hashmap) core-разработчик проекта Grin - @lehnberg (https://github.com/lehnberg) член Grin core team (выступление на английском, возможно видеотрансляция) Темы выступлений добавятся позже.

Hey guys! I added some updates to my previous launch day guide to mining Grin Coin (GRIN) where we took place in mining right after the genesis block (initial block of the blockchain for GRIN). This guide can be viewed here.This blog post on the VoskCoin Medium is focused on two key updates you need to know about mining the most profitable coin in cryptocurrency right now (which is GRIN if you did not already know).For the official VoskCoin video walkthrough on how to buy & sell Grin Coin without using the GRIN wallet + Updated mining guide with the fastest GRIN miner please watch it here!First I am going to focus on how to buy and sell Grin Coin w/ Bitforex exchange which you can sign up for here w/ our link to help support more posts about Grin Coin and other popular cryptocurrencies. http://voskco.in/BuySellGrinAre you a member of the VoskCoin Discord server yet? Join the Grin Coin mining & Buying+Selling discussion there! http://voskco.in/Discord2Before I go further into the method of buying & selling GRIN without a Grin Coin wallet I do want to clarify that you can also use the standard IP method with the Grin Coin wallet if you’d like to do so. Simply navigate to your deposit section on Bitforex and click GRIN from the drop down and you will have an address generated for as shown below.It’s a very simple process to buy and sell GRIN without a Grin Coin wallet, after signing up with Bitforex which has not blocked me for being a US citizen which sadly many cryptocurrency exchanges do — you will need to locate your UID numberOnce you have generated your account with Bitforex head back to F2Pool and you will need to have created an account with them and accrued a GRIN balance of over 5 GRIN — they payout automatically once a day between 0000 UTC and 0800 UTC.Next you will navigate to your account settings and then your payout settings. From there you will select Grin-29 which is the GPU algorithm for GRIN.Bitforex has been and still is the largest exchange for Grin Coin by GRIN volume and that is why I chose it along with the simple UID method for payout. Simply input your UID after selecting Bitforex, confirm with your code and submit!At this point you can execute trade orders as you would on any other cryptocurrency exchange, and with a new emerging cryptocurrency like GRIN I am sure I don’t need to explain the absolute basics to you — you’re on the bleeding edge of crypto tech! Just place your sell or buy order at the Bitcoin BTC value you would prefer (which the exchange will show you the USD valuation of that said Bitcoin) and click! You can click an open order to either buy or sell at that price also.Thats it! You have successfully bought or sold Grin Coin, you can initiate a Bitcoin withdrawal from their site if you’d like (recommended). For this you will need to sync it with google authenticator (a free 2fa app) as well as input a personal 6 digit security code — this is separate from the google 2fa. I have successfully withdrawn Bitcoin from Bitforex, as shown below.Cryptocurrency is rapidly changing and evolving, within cryptocurrency is cryptocurrency mining which is also . . rapidly changing and evolving. Grin Coin mining has been advancing at a rapid pace, which can be expected with all of the press GRIN has been receiving. This is an updated guide with the FASTEST miner for Grin Coin to enable you to earn the most profits / acquire the most GRIN mining at no cost in dev fee % or power usage — this is simply the latest GRIN miner with the highest hashrates on Nvidia and AMD GPUs.Bminer has currently lead the way in Grin Coin GPU mining with the fastest GPU miner, their latest release puts them ~40% faster than the leading alternative Grin Gold miner.First lets start with How To Mine Grin Coin GRIN on WindowsYou can download the latest version here http://voskco.in/GrinMinerOnce downloaded and extracted (if you need a free Windows extraction tool, peazip works well) you will then open the GrinningV2 folder and right click mine_grin and edit this file (its a start bat file) by replacing my username with your username you have created on F2Pool.That is it. . it is that simple to start mining Grin Coin GRIN on your Windows PC or Mining Rig — if you are wondering about what the best overclock settings for your GRIN mining rig are — normally +150–+200 core & +500–+700 memory and 75%-85% Power Limit(PL) or 125 watts. These numbers will vary depending on what graphics cards you are using. For example my 1070 TI mining rig that is mining Grin Coin is getting excellent results with +150 core +500 memory and 75% power limitIf you are having issues with your Windows mining rig, increase your virtual memory to 64 GB following this guide here — http://voskco.in/VirtMemHow do you mine Grin Coin GRIN on Linux you ask? I’ll show you how with Simple Miner smOS!Step one you will need to download and install Simple Miner smOS onto a USB drive / your mining rig — download here http://voskco.in/smOSBelow is a video guide by VoskCoin on how to flash your USB for smOSOnce you have Simple Miner smOS installed, you will need to create a group config for the latest/relevant miner — in this example we will be using bminer v13After clicking group config on the left bar of the Simple Mining smOS site you’ll click add group and then select or search for the miner you want, in this case searching bminer is the quickestAt this point you can copy and paste the below configuration into the latest version of bminer and replace voskcoin with your username that you registered on F2Pool with.Next you will click back over to Rig List and check the box(es) next to the miner(s) that you want to mine GRIN with and then click group config and choose the configuration that you just created. You will then click save and you are now successfully mining Grin Coin! You can check the current status of the miner / your mining rig by clicking console in the smOS dashboard.You now (hopefully. . .) know how to easily buy and sell Grin Coin if without using the Linux CLI GRIN wallet.

Why GPU mining is making a comeback with Grin! 5 min readIf you asked a PC gaming enthusiast what it was like to buy a graphics card during 2017 and much of 2018, youll likely be met with a nervous shudder, as if youve forced them to re-live a deeply traumatic event. As cryptocurrencies soared in value during that period, GPU mining also soared in popularity.However, as the value of certain cryptocurrencies fell, and ASIC mining started to dominate, it quickly became unaffordable to mine on a GPU. Put simply the investment in hardware and electricity didnt get enough of a return to make it worthwhile. And thus, the era of GPU mining was over, never to return. Or was it?Grin and bear itWhile Bitcoin and Ethereum are perhaps the most famous cryptocurrencies, there are actually 2,534 different currencies on the market. However, despite so many currencies on the market, the recent buzz centers around so-called privacy coins, which focus on secure and anonymous transactions and aim to address some weaknesses with existing cryptocurrencies. One privacy coin, in particular, is generating a lot of excitement, and could also signal the resurgence of GPU mining; this coin is called Grin.Grin is really a wizard!Grin is an implementation of MimbleWimble, which is a blockchain protocol first proposed in 2016 by an anonymous cryptographer named Tom Elvis Jedusor. This name, along with MimbleWimble and Grin itself are all semi-cryptic references to Harry Potter (see boxout for more).MimbleWimble is a privacy-by-default blockchain that is designed to be scalable, and the Grin implementation addresses some key concerns with existing currencies. For example, the fact that Grin has no addresses means that transactions cannot be traced or linked back to an individual. You might think this is already true of other currencies, such as Bitcoin. But although a Bitcoin address is anonymous, the blockchain and every transaction is open. This means that individuals could be connected to certain transactions for example, a purchase at an online retailer that stores personal information about you as a cookie. And once your wallet is linked to your identity, your entire transaction history can be traced.Its all Fungible games until someone gets hurtPrivacy is a crucial factor in fungibility, which is ensuring that the values of items of the same type are the same. For example, a 1 coin is the same value as every other 1 coin in the world, but a diamond may have a radically different value to another diamond of the same mass, depending on many quality factors. The fact that Bitcoins could be linked to individuals, and perhaps to criminal activity, means that, in the future, Bitcoins with a transaction history may end up being worth less than those with no transaction history.Grin also dramatically reduces the size of the Blockchain by removing the majority of past transaction information, which means only a fraction of the data is stored compared to other coins. This helps to ensure that transactions wont become unwieldy, which is a problem that Bitcoin faces, for example.Grin is also driven by the community and is focused on decentralized development. As Grin developer Yeastplume said in statement 1 : We are not driven by profit or corporate interests Were open-source and community-driven by design.All this sounds completely CuckooAs with other cryptocurrencies, transactions are validated and added to the blockchain through the process of mining. For Grin, this involves solving a memory-bound graph-theoretic proof-of-work algorithm called the Cuckoo Cycle, with miners rewarded in the currency for their efforts.Grin will actually launch with two proof-of-work algorithms a primary algorithm called Cuckatoo, which is ASIC Friendly (AF) and a second algorithm that is ASIC Resistant (AR) called Cuckaroo, which can be mined by CPUs and GPUs.The great news for GPU miners is that, at least initially, 90% of the rewards will be for mining the AR Cuckaroo algorithm. This is intended to slow the growth of ASIC miners and encourage a decentralized mining market. The AR Cuckaroo algorithm will fork every six months to thwart ASIC domination (the AF Cuckatoo algorithm does not fork), but the rewards decrease 3.75% per month until there are essentially zero returns after two years. At which point, a range of ASIC miners should be available to provide competition and maintain decentralized mining.The rise of the RadeonHowever, although GPU mining will eventually tail off, there is a tremendous opportunity for first-movers to take advantage of the high rewards from early mining. Just as long as you have the right hardware. This is where Grin differs from Bitcoin for example, because while Bitcoins proof-of-work algorithm is based on SHA-256, which requires a huge amount of processing power, the Grin algorithms are memory bound. In fact, the GPU-friendly Cuckaroo algorithm could require greater than 5.5GB of video memory, while the ASIC-friendly (AF) Cuckatoo algorithm at least 11GB of memory. Extra memory will, of course, make processing Cuckaroo and Cuckatoo even faster.While most mid/high-end GPUs have at least 8GB of memory, very few have more than 12GB, and 16GB will be required to mine using the 2020 variant of Grin Mean AF Cuckatoo algorithm. A GPU with a 16GB frame buffer could conceivably mine both the GPU friendly and ASIC friendly algorithms for more than 2 years whereas others are limited to just the GPU friendly Cockaroo after the first year. Mining the latter on GPU, before ASIC miners come to market, means less competition and a higher probability of winning a block reward. But no such GPU exists, at least at an affordable price or does it?The money printing machineInnosilicon Technology looks to have a great early-mover advantage thanks to the release its G321800, G32500 and G32-mini The card and devices are available to order now from:Innosilicon G32-1800 GRIN Coin MinerModel G32-1800 from Innosilicon mining 2 algorithms (Cuckatoo31+, Cuckatoo32+) with a maximum hash rate of 328GPS for abitindigi.comInnosilicon G32-500 GRIN Coin MinerModel G32-500 from Innosilicon mining 2 algorithms (Cuckatoo31+, Cuckatoo32+) with a maximum hashrate of 100GPS for abitindigi.comInnosilicon G32-Mini GRIN Coin MinerModel G32-Mini from Innosilicon mining 2 algorithms (Cuckatoo31+, Cuckatoo32+) with a maximum hash rate of 21.5GPS forbitindigi.comMining on GPU has been a rollercoaster ride over the last couple of years, but with the rise of privacy coins and the huge interest in Grin, 2019 again promises to be a profitable year for GPU miners, providing you move fast and take advantage of the best available hardware.[Boxout]Youre a miner, HarryGrin makes numerous references to J K Rowlings Harry Potter novels. Heres what those references meanGrinNamed after Gringotts Wizarding Bank in Diagon Alley, the safest place in the wizarding world, hinting at the secure, private nature of Grin coins.MimbleWimbleThe name of the Tongue-Tying Curse first uttered by Gilderoy Lockhart in The Chamber of Secrets. It also hints at the privacy element of Grin, which is based on the MimbleWimble privacy-by-default blockchain protocol.

For a new cryptocurrency, Grin sure is making a lot of investors happy these days. The privacy coin, which only made its debut a month ago,  has already scored listings on at least two leading crypto exchanges — Bittrex International and Poloniex. Many older coins, or at least their communities, are still dreaming of accomplishing this. But there is something different about Grin.Grin is an open-source project that uses the Mimblewimble protocol for scalability, privacy, and fungibility, features that are increasingly attractive to crypto investors these days. The name is a reference to the Gringotts bank in Harry Potter, which is also the origin of Mimblewimble. And, similar to bitcoin, Grin's founder (for lack of a better word for an open-source decentralized project) is anonymous, using the wizardly pseudonym Igno Peverell.Grin is also 100% donation-driven. This means that many of its developers, who are feverishly working on making Grin more accessible to the mainstream, also have day jobs. There is no foundation backing them or founders reward, or any other cushy features.Grin developers, it seems, wouldn't have it any other way.  Software development engineer Daniel Lehnberg told Crypto Briefing:"Arguably it's the community that got me sucked into the project after having read about it, and it's the biggest asset we have I would say."Maybe that's why the exchange listings didn't go to their heads. Peverell told Crypto Briefing:"We try to keep developing Grin and make it a great project and great community and to not worry too much about externalities and [things] we don't really have control over."That's not to say that Grin doesn't engage with exchanges, however. "In terms of effort we undertake, we try to answer earnest questions by serious exchanges to the best of our abilities," noted Lehnberg, adding:"Personally, I don't find them important at all. It's early days. It's nice with validation, but we have a lot of work to do. That's the beauty with a project team that doesn't have interests aligned with price movements – we work to advance the community and ecosystem, not to make the price go up and down."What they are focused on is "buidling." As Lehnberg noted: "[Grin developer] @yeastplume has been busy getting us windows support, which is really nice."  When that becomes a reality, users can run a wallet and a fully synced node from a Windows environment."We're also trying to foster more wallet development [and] provide libraries to make those easier to build for the community," added Peverell.If other new coins are taking notes, the crypto community has been particularly impressed with Grin's anonymous and decentralized model, one that skipped the ICO in favor of reserving token issuance to the proof-of-work (PoW) mining system.This is what inspired Circle-backed Poloniex to list the token.  The crypto exchange stated: "We believe in supporting crypto projects which encourage distributed, voluntary development and fair, decentralized methods of token distribution. " Not only is Poloniex listing Grin but their engineers had to do extra work to support Grin's privacy and scalability tied to Mimblewimble. The exchange is also shouldering a percentage of the GRIN trading fees for the next 12 months in a nod to the project's donation-fueled model — 50% for the first month and 25% for the balance of the period. Not to be outdone, Bittrex International is slashing Grin trading fees by 75% through Feb. 22, 2019.At this rate, other big crypto exchanges could be exploring a listing of their own.I think it's fair to say that the regulatory risk in @grinMW is comparably small. That's why we see US exchanges such as @BittrexExchange and @Poloniex listing. Another upside of decentralization/fair launch. I wouldn't be surprised if @binance and eventually @coinbase listThe Bittrex listing was actually on the non-U.S. international arm of the exchange. Since Feb. 8, however, the day before that listing, Grin has added 20% to its value.What's their secret sauce?

March 27, 2019 BitcoinPrice Cryptocurrencies News, Home Page, How to Buy Bitcoins, What is Bitcoin 0 Developers behind privacy-oriented coin Grin are discussing crucial, potential changes to the cryptocurrency’s hard fork roadmap.Since plans to keep mining decentralized through a series of system-wide upgrades (more popularly known as “hard forks”) may not pan out quite as well as Grin developers have hoped, they are looking to potentially adjust the upgrade schedule.Prominent Grin developer John Tromp, who invented proof-of-work mining algorithm Cuckoo Cycle, suggested during a bi-weekly Grin Governance meeting today changes to what will go into the next hard fork currently set for mid-July. Now, developers are putting the matter to a vote in two weeks time.Tromp argued in conversation with other developers:“The announcement of single chip ASICs for [Cuckatoo-31] has undermined our phase out schedule… which looks like it won’t be able to serve its original intended purpose of thwarting single chip ASICs in the foreseeable future.”ASICs are expensive, specialized hardware devices designed to optimize earnings for a specific mining algorithm. Developers think it’s bad that ASICs have come to dominate many cryptocurrencies, since the manufacturers are a centralizing force in what’s supposed to be decentralized cryptocurrencies.When Grin started off, its developers aimed to prevent a “first-mover advantage” towards ASIC manufacturers, instead attempting to promote healthy competition with manufacturers of GPUs, which are less expensive to run. To keep ASICs at bay, Grin developers agreed to hard fork the network every six months and tweak the mining algorithm slightly for a period of two years.However, such algorithm adjustments were also deemed to be an unsustainable solution to miner centralization in the long-run. As such, developers agreed that over time the network would gradually transition to an explicitly “ASIC-friendly” variant of Tromp’s Cuckoo Cycle called Cuckatoo31+. This would give ample time for many ASIC manufacturers to optimize for this mining algorithm and hopefully ensure a decentralization of ASIC miners on the network.But this might not be going as planned. At present, roughly 81 percent of Grin blocks are being mined using the ASIC-resistant and tweakable variant of Tromp’s Cuckoo Cycle called Cuckaroo29. The other 19 percent of blocks are mined using Cuckatoo31+, according to Grin ASIC manufacturer Obelisk CEO David Vorick.In a phase referred to in Tromp’s statements today as the “Cuckatoo-31,” this ratio continues to gradually decline. As developer Daniel Lehnberg estimates in today’s meeting, Cuckatoo-31 is expected to end August 19 of next year. The following phase – Cuckatoo-32 – will result in a total of 55 percent of Grin blocks mined using Cuckatoo31+. Thereafter, the beginning of Cuckatoo-33 in 2023 marks the phase transitioning to a fully Cuckatoo31+ mined Grin network.However, this current schedule might lead to problems. Both Tromp and Vorick argue that the present schedule needs to be delayed. If not, Vorick maintains that “it will almost guarantee there will be an [ASIC] monopoly at [Cuckatoo-32],” which is exactly what the Grin developers were trying to prevent.“We’ve demonstrated with our single-chip [Cuckatoo-31] miner that multi-chip designs are not competitive, and if the phase-out is not delayed, we will be producing a [Cuckatoo-32] single-chip design as well.”This Cuckatoo-32 design “will be expensive and difficult [to build] and will make competing very difficult,” Vorick adds.“We believe that the mining ecosystem for Grin would be better if it stayed at [Cuckatoo-31], where costs are lower and it’s easier for new competitors to get involved,” said Vorick to CoinDesk.“Any change to [Cuckatoo31+] cannot take effect until at least 18 months into the future, unless agreed upon by all affected parties.”“I’m proposing to proceed with more caution, to take a wait and see approach,” said Tromp. “But also to keep our commitment for the next 18 months as ASIC manufacturers must be able to rely on that for investment decisions.”Writing on a public Grin forum, Vorick shared his concerns about the phased hard fork roadmap. He explained that while other mining hardware manufacturers “are not upfront about the nature of their hardware,” his motivation for disclosing the matter came down to Obelisk wanting “give the community all the information it needs to make informed decisions.”“We really would like to see Grin [succeed] and we would like to do so by collaborating with the Grin community and letting them know what’s going on before it happens,” wrote Vorick. “We’re looking forward to your thoughts and discussion.”Taiwanese Development Council to Form Blockchain Alliance in Three MonthsXDAT steps into the cryptocurrency space; aims to become a global trusted brand – AMBCrypto NewsAhead of its hotly anticipated launch, bitcoin futures exchange Bakkt has launched a hiring campaign.

Since its January 15th mainnet launch, Grin began trading momentarily above US$250, fell all the way to $2.50, climbed up to $15, and fell once more below $7. All eyes have been on this exciting project, and speculators across the space are itching to know: where does it go next?While its initial trading in the three figure range may have been a blemish more than anything else, the rise back to $15 was legitimate, and propelled by tens of millions in daily volume despite a lack of access on top exchanges. Fueled primarily by markets on Hotbit and Bitforex, optimists saw $15 as just the beginning, while skeptics argued that GRIN would never see that price again.At current prices of US$6.85, GRIN carries a respectable market cap of roughly $9 million. With daily volume continuing to exceed $10 million, interest in GRIN remains among the highest of all coins. To get a better understanding of why GRIN has made such a buzz, and where it might be headed next, an understanding of the basis of the project must be established.Grin, alongside recently launched Beam, represents a pioneer of MimbleWimble technology. MimbleWimble is a novel approach to distributed ledger technology: a lightweight blockchain alternative that eliminates all unnecessary bloat in favor of maximum privacy and scalability. Grin is unique from other cryptocurrencies in that it operates in the absence of addresses, transaction amounts, and transaction histories. Additionally, it was developed by volunteers in the absence of an ICO since soon after MimbleWimble was first introduced in 2016.Much of the initial hype around Grin came from the support of prominent Bitcoin Core supporters, who have suggested that Grin represents one of a select few instances in which an altcoin represents a worthwhile initiative. This support was highlighted best by the decision by Theymos for Grin to be accepted on Bitcointalk, the first currency accepted beyond Bitcoin.If you stop your analysis without looking at Grin’s tokenomics, it probably looks clear that it still has room to appreciate in value significantly. However, the emission schedule of Grin represent a monumental dilemma for traders and, even more so, for long term holders.The maximum supply of Grin is infinite, and its emission schedule is constant. 60 Grin is awarded every block, and with block times fixed to one minute, that represents one new Grin minted every second for eternity. Per day, that translates to 86,400 new Grin every day. At $6.85 per Grin, almost US$600,000 in new money needs to enter Grin every day just for the price to remain constant. If, for the next 24 hours, there was no net change in the money invested in the ecosystem, Grin would fall to $6.43.As a point of reference, US$6.3 million needs to enter Bitcoin every day to offset the introduction of new coins from block rewards. Grin would match that number at a price of $73 per coin. Alas, the calls for $300 Grin do seem highly unlikely.It’s also important to keep in mind that for every day that passes, more money needs to be put towards buying Grin for the price to increase. For example, for Grin to hold at $6.85 by end of year, the market cap would need see growth of over US$195 million.Alas, traders and speculators must weigh the trade-off between technology and tokenomics when handling Grin. With such an intense emission schedule, one must feel very strongly about what Grin brings to the table as a prerequisite to accumulate it. US$15 per Grin certainly isn’t an insurmountable feat, but that amount of growth is a greater obstacle to Grin than most other cryptocurrencies.

The latter is a digital asset that is based on the Mimblewimble Blockchain, and it aims to give privacy to parties involved in a transaction. Reportedly, this digital currency exchange is the second to have launched GRIN.KuCoin Announces the Launch of GRINKuCoin on its Twitter page and blog announced the launch of Grin (GRIN), a cryptocurrency that runs on the Mimblewimble Blockchain. Per the exchange’s post, the coin could be deposited into wallets from January 24, and its withdrawal began on January 26. Also, three cryptocurrencies can be traded for GRIN, and these are Bitcoin (BTC), Ethereum (ETH), and Tether (USDT).Grin (GRIN) is now on KuCoin, you can deposit now. Trading pairs include GRIN/BTC, GRIN/ETH and GRIN/USDT. Buying starts Jan 24, 2019, 17:30 (UTC+8), selling starts Jan 24, 2019, 18:00 (UTC+8) and withdrawal opens Jan 26, 2019, 18:00 (UTC+8).@grinMW #KCS #GRIN #BTC #ETH #USDT pic.twitter.com/8IzidvrN6L— KuCoin Updates (@KuCoinUpdates) January 24, 2019A media outlet’s report on January 25 also reveals that during the coin’s launch, it was trading at around $261. However, CoinMarketCap’s data, as at press time shows that the price of this digital asset is $13.14. The sudden decline in value within a short period is said to be partially caused by the infinite supply of the coin.Privacy Coin Based on Mimblewimble BlockchainGRIN is reportedly a privacy coin because it is based on the Mimblewimble Blockchain that seeks to hide the details of a transaction from an onlooker. As a result, only the parties transacting will be aware of the exact amount that has been sent. This Blockchain is believed to solve one of the problems of existing distributed ledger technologies which do not make transactions confidential.According to KuCoin:MimbleWimble provides extremely good scalability, privacy and fungibility by relying on strong cryptographic primitives. It addresses gaps existing in almost all current blockchain implementations.KuCoin Says GRIN Aims to Bring About Simplicity and Save SpaceAsides being reputable for its privacy, KuCoin outlined that GRIN aims to bring about simplicity which will make its auditing easy. In the same vein, it saves space during transactions since it scales minimally depending on the number of transactions, and scales more with the number of users. Other than the Singapore exchange, investors who may be interested in trading the digital asset can find it on Hotbit.On December 26, BTCNN  informed of KuCoin’s delisting of 10 tokens for not maintaining the listing standards. Among the delisted tokens are Jibrel Network (JNT), Mobius (MOBI), WePower (WPR), Modum (MOD), BitClave (CAT), and EthLend (LEND). As a result of the removal, users were unable to deposit such tokens on the platform.

A few weeks ago Giacomo Zucco held a YouTube live Q&A for Cryptonomist in which he answered many questions from the readers, but not all. In the first part of the interview – published two weeks ago and realised by collecting these questions – Zucco talked about RGB and Lightning Network, and in the second part, he expressed his opinion about Stellar Lumens and Cardano.In this third part, he talks about MimbleWimble and Grin.My view of MimbleWimble is very positive. MimbleWimble has a very elegant and beautiful design. If the technology behind MimbleWimble had been field tested and found safe before Bitcoin I wouldn’t have regretted if Bitcoin had used this very elegant way of mixing binding and hiding. However, in turn, this design creates the need to develop some other choices, such as the client-side-validated model and the “scriptless-script” contracts, which are, on the one hand, more complex and difficult to develop and adopt, but on the other, much more secure, private and scalable than the models adopted in Bitcoin. MimbleWimble guarantees excellent anonymity at the basic level and has some small (and often exaggerated by those who talk about it) advantages of scalability. Privacy is very good because it allows concealing both who is sending the payments and the amount involved. Scalability is slightly better in the sense that it is possible to compact the history of global consensus. There is no real blockchain, there is a chain of objects called Kernels that can be compacted by bypassing some circular steps of payment. Thus it is a very good design. Moreover, the way in which this design has been promoted is very beautiful from an ideological point of view, because as in the case of Satoshi Nakamoto, it appeared on the Internet from an anonymous source, attracting the attention of leading experts, in order to undergo a strict peer review. A very elaborate and refined idea, without launching an ICO, without asking for money, without promoting products, sharing the knowledge on the subject and from there the MimbleWimble protocol has been worked on by many people, especially the Blockstream researcher Andrew Poelstra but also others who started to analyze and expand the idea.Furthermore, Andrew’s contribution is very important because the protocol initially proposed by the pseudonym, which called itself with the French name of Lord Voldemort taken from Harry Potter’s books, could not support Lightning Network (which already represents the main perspective of privacy and scalability for Bitcoin). It couldn’t actually support any kind of script, i.e. smart contracts, whereas Andrew Poelstra not only refined, fixed and improved the encryption of MimbleWimble but also added the possibility of making (“scriptless”) complex scripts, which theoretically allow using Lightning Network on MimbleWimble. I am, however, very sceptical about attempts to turn it into a production project at the moment. Consider that neither the creator of MimbleWimble, which then disappeared, nor the main researchers such as Andrew Poelstra who developed the most complex parts, have ever launched an altcoin based on this design, because what they are waiting to do is either, in the very distant future, to add it to Bitcoin with a system called extension blocks, or in a shorter time to test it on Bitcoin’s sidechains.In order to experiment with a new architecture, it is not necessary to launch a new economic asset; on the contrary, it would be decidedly better not to do so from different points of view: to avoid adding the uncertainty of an economic test to the experimentation of an infrastructure. So Andrew Poelstra and other MimbleWimble researchers are waiting to try MimbleWimble on Bitcoin’s sidechain. MimbleWimble will arrive on Liquid, eventually, which is a federated sidechain. And then later it could reach other types of sidechains. There is already a test on an experimental testnet sidechain called Elements Alpha. In contrast, Grin is an attempt to launch a new altcoin, something of which I am generally sceptical from an economic point of view as is already known. In addition, there are other things about Grin that make me quite sceptical in particular, such as the specific monetary policy in which there’s high inflation. Grin’s inflation will not fall below the level of the current US dollar inflation for more than 50 years, while bitcoin will have inflation lower than the US dollar as early as next year, 10 years after its creation, so Grin is a very inflated currency. Which is not a good idea in my opinion in terms of economic theory. Furthermore, from a Proof of Work point of view, it is a rather unusual move to mix ASIC resistant algorithms with ASIC friendly algorithms. That said, Grin’s team is one of the ones that in my opinion are working on an altcoin that has at least a scientific and technical interest. Another example is Monero. Grin is interesting to see as an experiment, although I would advise against its use in production by anyone, however, it is definitely a scientific experiment worth following. I think I’ll keep a close eye on it, unlike further implementations of MimbleWimble, such as BeamMW, which I find less interesting.Reporting the Future The latest news about Bitcoin, ICO, trading, blockchain and fintech.Stay updated on all the news concerning cryptocurrencies and the whole world of ICO
