Garzik Forks UnitedBitcoin Away from "Maximalists" to Support Altcoin Communities

Garzik Forks UnitedBitcoin Away from "Maximalists" to Support Altcoin Communities

A new project called UnitedBitcoin (warning: the site autoplays audio) promises to add smart contract features using the UTXO model, support for the lightning network and SegWit, and eight-megabyte blocks. Headed up by Jeff Garzik, the lead developer behind the failed SegWit2x hard fork, along with Matthew Roszak and SongXiu Hua, this UnitedBitcoin (UB) hard fork will offer replay protection to prevent people from accidentally spending their coins on both the Bitcoin and the UnitedBitcoin blockchains.

Garzik told Bitcoin Magazine that “10% of the total worldwide SHA-256 hash power” has moved to the new UB network, with much of the support coming from China and older mining equipment that was no longer profitable due to the escalating difficulty in mining bitcoin. He noted that UB is already supported on the ZB and EXX exchanges.

The UB white paper outlines how lost bitcoins have created deflationary pressure that has pushed the price up. Because those bitcoins are out of circulation, the supply is further decreased. One of the issues that UB seeks to address is to find a purpose both for those lost bitcoins and for “inactive” wallets by creating a stable cryptocurrency linked to their addresses.

All active Bitcoin addresses will receive the same balance on the UB chain, much like previous forks. The balances of UB on inactive addresses, however, will be confiscated by the UB Foundation and used to “serve the community.”

Inactive addresses are defined in the white paper as “addresses without activity since block height #494000 (November 11, 2017) and as a result didn’t automatically receive UBTC during phase 1 of the asset allocation procedure.”

UB does not distinguish between an “inactive” address and one which is simply being used by a long-time "hodler."

“There is no difference. An inactive account is an inactive account,” said Garzik. “Like during [the] Ethereum new coin creation, you had to take a proactive step, otherwise you got zero [ether]. This is normal for new token creation — new chain, new ERC20, but different from all other Bitcoin Forks. We are trying to do something new and different.”

Anyone with a prior balance of 0.01 BTC in an “inactive” address at the time of the November 11 fork can still get UB tokens, so long as they are willing to take such a “proactive step”: that is, they make at least one transfer to their own Bitcoin address between Block 498,777 and Block 501,878 (December 12, 2017, to 12:00 GMT on January 3, 2018).

Only the original address can make the transfer to itself, and the receiving address must be used as one of the sending (input) addresses.

One privacy issue to consider is that in order to “proactively” claim BU tokens, the protocol forces users to reuse their Bitcoin addresses; this action puts privacy at risk and, unless it is done carefully, may link many of the users’ coins together.

It's a gold mine for blockchain deanonymization, merging up UTXOs and reusing addresses. Can't help but think such an artificial qualification is deliberate.

— Johnathan Corgan (@jmcorgan) December 13, 2017

User privacy protection is not the only part of the protocol that is drawing criticism, however.

“The code contains a god mode; it’s literally called that,” Blockchain developer Sjors Provoost said to Bitcoin Magazine. He said that it appears as if this “god mode” will create a multisignature address that belongs to a (yet-to-be-defined) UnitedBitcoin Foundation.

“Unlike previous airdrops, the initial coin distribution is not determined by a consensus rule,” he added. “This means that even if you were to run the full UB node software (which you should not), you will have no way of knowing for sure how many coins you get. Conversely, if you already had bitcoin, you won’t know how many of ‘your’ coins will be confiscated. You simply have to trust their promise to take and redistribute coins as their marketing promises.”

According to Provoost, the new consensus rule allows the owner of this foundation address to spend any UTXO they want. “These confiscations will be included in holy blocks, which can be created during the first 500 blocks after the fork. This is how they implement the redistribution as I just described, but they can do much more.”

Furthermore, Provoost is concerned about the quality of the code itself. “Garzik’s previous project SegWit2x tried to keep its changes relative to Core to a bare minimum. Although at the time of the planned fork their code base was about a year behind Bitcoin Core, it didn’t introduce many changes,” he pointed out.

“UnitedBitcoin on the other hand has introduced far more changes, making the task of tracking Bitcoin Core far more difficult. It’s not as many changes as Bitcoin Unlimited and Bitcoin Cash, and the problem is somewhat mitigated by them sunsetting the more complicated consensus changes like god mode. However, even the small change in SegWit2x had a widely publicized serious bug in it and there are rumors of more.”

What Happens to Those “Reclaimed” Tokens?

Garzik has plans to “build a better Tether” by using the UB reserve, funded by coins reclaimed from “inactive” addresses. According to the project, 70 percent of confiscated UB coins will be held as collateral to issue stable tokens pegged to a fiat currency.

“The UB reserve can be used as a backing asset for a stable, non-volatile currency,” said Garzik. “This is auditable and transparent and on the blockchain. It will be over-collateralized, 200–300% to maintain the stability even in the face of a volatile price of the reserve.”

The remaining 30 percent of the confiscated coins will support another new feature: owners of QTUM, H-shares and ether will receive a share of the remaining redistributed UB.  

UB is experimenting with a new model: engage multiple communities — ETH, Qtum — rather than following the tired model of rewarding Bitcoin maximalists with a coin they dislike and will just dump on day 1.

According to Garzik, the specific claim process for the redistribution of UB has yet to be determined. “The UB board is still being put in place — things are moving very fast — and this will include more specifics on governance and community allocations.”

The scheduled timeline of what has been released and what is coming breaks down as follows:

December 12, 2017:

Fork of Bitcoin to UnitedBitcoin (at block height #498,777) with support for:

  • Increased block size to 8 MB

  • SegWit support

  • Replay Protection

  • Asset Allocation

January 3, 2018:
  • End of Asset Allocation phase #2

  • Pegged currency based on color currency

February 28, 2018:
  • Launch of smart contract support

April 28, 2018:
  • Launch of lightning network support

Japan's GMO Internet Group Will Pay Thousands of Workers in Bitcoin

Japanese Firm GMO Will Pay Thousands of Workers in Bitcoin

Blockchain development companies and the cryptocurrency press have been paying their workers in cryptocurrencies for years, but one realizes that the times are truly changing when mainstream companies start paying their workers in bitcoin.

GMO Internet Group, a Japanese provider of a full spectrum of internet services for both the consumer and enterprise markets, is introducing a system for employees to receive part of their salary in bitcoin.

Headquartered in Tokyo, GMO Internet Group comprises more than 60 companies in 10 countries. In view of the group’s size and financial muscle, this initiative is likely to boost the mainstream adoption of the practice of paying salaries in cryptocurrencies.

The move is partly motivated by the desire to promote the adoption of Bitcoin, which is a strategic priority for GMO. In fact, the group is vigorously active in bitcoin trading and mining services, as well as mining hardware development. Therefore, anything that is good for Bitcoin is also good for GMO.

In May 2017, GMO launched a cryptocurrency exchange, initially dubbed Z.com Coin and later rebranded as GMO Coin, which features cryptocurrency FX and trading on both computers and smartphones. The exchange offers two types of services: cryptocurrency FX, which is an over-the-counter (OTC) bitcoin margin trading and cryptocurrency trading, which enables buying and selling of virtual currency in JPY in addition to basic features allowing customers to send and receive bitcoins.

In September 2017, GMO announced the upcoming launch of a new bitcoin mining business. “We will operate a next-generation mining center utilizing renewable energy and cutting-edge semiconductor chips in Northern Europe,” GMO stated, emphasizing that they will invest in R&D and manufacturing of hardware including the next-generation mining chip.

“We will use cutting-edge 7 nm process technology for chips to be used in the mining process, and jointly work on its research and development and manufacturing with our alliance partner having semiconductor design technology.” The mining business is scheduled to start in January 2018.

GMO expressed its belief that cryptocurrencies will develop into “new universal currencies” available to anyone from any country or region who wants to freely exchange value, “creating a new borderless economic zone.”

The option to receive part of the salary in bitcoin will initially only be available to employees of one GMO company — GMO Internet Co. Ltd. — starting in March 2018, but it will be gradually extended to more than 4,000 employees in other GMO companies based in Japan.

The minimum bitcoin payment will initially be 10,000 yen (~$88) and the upper limit will be 100,000 yen (~$881). Each salary payment in yen will be reduced by the amount of bitcoin paid, using the exchange rate at the GMO Coin exchange.

Mainichi Japan notes that Japan's labor code stipulates that businesses must pay employees in a recognized currency such as the yen, but, according to GMO, the move is in accordance with the law because any payments in bitcoin would be consensual, with a chosen amount to be deducted from paychecks and put toward purchasing bitcoin. The cryptocurrency is rising in popularity in Japan with an increasing number of retailers accepting it as a form of payment.

GMO Internet Group wants to contribute to the development of cryptocurrencies in the world by promoting cryptocurrency-related initiatives throughout the group. In particular, GMO wants to promote ownership of bitcoin among its employees — who can be the best evangelists for the group’s products and services related to the digital currency — to improve the employees’ exposure to and understanding of Bitcoin.

“Employers can now pay employees a portion of their net earnings in bitcoin by collaborating with niche payroll solution providers such as Bitwage, Wagepoint, or Bitpay, who manage the back-end mechanics, eliminate exposure to price volatility, and reduce compliance and governance risks,” noted Deloitte principal Eric Piscini.

A recent overview of cryptocurrency payroll processors and early adopting clients notes that offering salaries in bitcoin could make it easier for companies to retain and attract talent. Besides compensating current employees, “[cryptocurrencies] could help businesses more effectively tap into the open talent economy, where individual contributors may be drawn to business partners that offer payout features only cryptocurrency makes possible: fast peer-to-peer payments across country borders with minimal friction (or total freedom) from traditional banking systems,” said Piscini.

For now, the GMO press release is available only in Japanese.

Bitcoin Price Analysis: Bitcoin Rests at Tipping Point Before Deciding Next Move

Bitcoin Price Analysis

Bitcoin prices have currently stalled out in the $16,000s as the market decides if it wants to continue the ravenous bull trend or go through a more corrective phase. In the last 30 days, the price of bitcoin has doubled — entering into what most traditional market analysts would deem “bubble territory.” Bitcoin’s growth has been so rapid, it has managed to break north out of a parabolic trend to form an even more aggressive parabolic shape known as a “hypodermic trend.” Let’s take a look at the macro view of bitcoin and see if this trend is sustainable or ripe for a correction:

Figure_1.JPGFigure 1: BTC-USD, 1-Day Candles, Macro Trend

The image above shows a multi-year, parabolic envelope that, until recently, has guided the bitcoin bull market. Within the parabolic envelope we see a strong linear channel (shown in purple) that has provided very strong support and resistance through much of the bitcoin price growth. At the end of November 2017, however, bitcoin price growth was so strong, it managed to break out of both the linear and parabolic trends and form a more aggressive price trend: a hypodermic trend.

Figure_2.JPGFigure 2: BTC-USD, 60-Minute Candles, Hypodermic Trendline

The solid red line represents an aggressive support line that has guided this new, aggressive price growth out of the parabolic envelope. As of the time of this article, I am monitoring a trading range very closely as it nears this hypodermic trend. A breakdown below this hypodermic trend represents a diminished trend of demand in the bitcoin market, and it could ultimately lead to a local top on for BTC-USD. Paired with this hypodermic breakdown is a breakdown of the trading range (shown in blue) that has a span of approximately $5,000. A breakdown of a trading range that large would have quite a meaningful market reaction and is likely to see a profound correction before bitcoin buyers step back in.

However, before we get all doomsday-esque, it’s important to remember that distribution phases and reaccumulation phases are quite similar in shape and are called “evil twins” of one another. It’s entirely possible we could see new all-time highs out of bitcoin but, given the weak and anemic follow-through of each all-time high breaching the trading range, I am inclined to lean less toward accumulation and more toward distribution.

As always, volume will be a huge indicator in this process; a great telltale that we are, in fact, in an accumulation phase will be volume growth coupled with price growth. If we begin to push new highs and we see a volume growth trend combined with it, there will be a great sigh of relief from traders as this pairing will indicate increasing demand and diminishing free-floating supply in the market.

Summary:

  1. The price of bitcoin has doubled in the last month.

  2. The price growth has been so aggressive that it has broken north of a parabolic trend it’s been well-confined within for 3 years.

  3. Bitcoin is at a crucial point as it currently decides whether it wants to move up or down in price.

Trading and investing in digital assets like bitcoin and ether is highly speculative and comes with many risks.

IcyWallet Offers a Cold Storage Bitcoin Wallet for the Visually Impaired

IcyWallet Offers a Cold Storage Bitcoin Wallet for the Visually Impaired

Safely storing cryptocurrency can be confusing, especially for newcomers to the space, but for people with visual impairments, finding an accessible option is especially challenging.

IcyWallet is a cold wallet with a difference: it is designed to make it as simple as possible for people with visual impairments to manage offline bitcoin storage.

The project got its start when Adam Newbold and his wife took a braille reading course as a learning activity. Shortly afterward, Newbold struck up a Reddit conversation with a blind Bitcoin enthusiast who expressed frustration with the lack of support for the blind community from Bitcoin software developers. None of the wallets worked correctly in his reader and he required help to perform any functions with bitcoin.

“I learned even more about practical accessibility issues and the real-world challenges that the blind encounter every day,” Newbold told Bitcoin Magazine. “This turned into a stronger personal interest that merged with my existing interest in Bitcoin when I realized that there are pretty big opportunities for improving the state of accessibility in Bitcoin software.”

He started a campaign in October 2017 to create a braille version of the original Bitcoin white paper. That campaign was successful and the document is now available for anyone wanting to get a copy.

That first success led Newbold to create the IcyWallet. His goal is to provide a 100 percent free and open source bitcoin hardware wallet for the blind. Work is currently underway with early milestones achieved, the progress of which is tracked on their website.

“One of the points you hear a lot about Bitcoin is that you can ‘be your own bank,’ which always sounds fun and empowering (and it is!),” said Newbold. “But it also means that you need to take responsibility for all of the things that banks do, like keeping your funds secure.”

He explained that even though today’s technology has solved a substantial number of issues that people with disabilities face, when it comes to bitcoin and security, there are still several missing pieces.

“There isn’t any kind of hardware wallet on the market today that’s fully accessible to people with blindness,” said Newbold, “and there are barriers to setting up secured, air-gapped solutions. This leaves people with blindness limited choices that all involve compromising security to some degree. With the IcyWallet, the private keys never leave the device.”

According to Newbold, here is how the device will work:

  • First, the transaction is generated on a (different) computer connected to the internet, so that the fee can be properly estimated;

  • Then, the transaction is signed by the IcyWallet device;

  • Finally, the transaction is broadcasted to the Bitcoin network back on the internet-connected device. This keeps the IcyWallet device completely offline, ensuring that the private keys are safe at all times.

Users simply plug in headphones and a keyboard or a refreshable braille display. The device boots directly into the wallet app with functional audio and braille support.

“Refreshable braille display support means that it will even support someone with deaf/blindness right out of the box,” said Newbold.

IcyWallet generates hierarchical deterministic wallets with mnemonic seeds for safe backup. The code is developed using the BitcoinJS library and is intended to be run on an “air-gapped” Raspberry Pi, though Newbold points out that, in theory, the software can run on other hardware.

Newbold has plans to make a demo video/audio track available soon, as well as an early release of the software (probably limited to wallet generation only) so that he can start to get more feedback and code suggestions that will improve the IcyWallet.

As Bitcoin in particular, and cryptocurrencies in general, see wider adoption, the implementation of greater accessibility systems will be important to their continued growth. IcyWallet is expected to launch at some point in 2018.

New In-Game Cryptocurrency Systems Let You Buy Assets in the Virtual Reality World

New In-Game Cryptocurrency Systems Let You Buy Assets in the Virtual World

High Fidelity is announcing the launch of Avatar Island, a VR domain where High Fidelity users can purchase items for their avatars, all contributed by digital artists from around the world.

High Fidelity is a next-generation platform for Virtual Reality (VR) worlds developed by Philip Rosedale, the creator of the once very popular Second Life. In September 2017, the company announced that it was developing a blockchain for intellectual property protection and an in-game cryptocurrency .

“I’ve been looking at blockchain technology since Second Life, as the Linden dollar was one of the first digital goods currencies,” said Rosedale. “At the time that Bitcoin came out, I was thinking a lot about how we could generalize what we did at Second Life. I didn’t have all of the ideas, but in the last few quarters we have been building the backend system to make all of this work.”

Different sorts of VR items, such as custom wearables for avatars (which were and still are very successful in the Second Life marketplace) will be sold and bought in Avatar Island through a new cryptocurrency running on a blockchain, which will also track the history and ownership of each item.

“[This] is the first beta release of the commerce system, which is a cryptocurrency-based content protection and payment system,” said Rosedale in the High Fidelity forum. “[Behind]  the scenes, the currency is actually stored on a ‘blockchain’ very similar to Bitcoin but supporting a higher transaction rate and lower fees. This blockchain also stores the PoP [Proof of Provenance] information for digital goods, meaning that both your currency and your digital property will exist in a public database and cannot be altered.”

Contrary to Second Life, where the only option available to external operators was to host their VR worlds on servers operated by Second Life developer Linden Lab, High Fidelity allows developers to host VR worlds independently. In November 2017, High Fidelity released an update that allows developers to rapidly deploy High Fidelity VR domains to the cloud, in collaboration with DigitalOcean. The distributed nature of the upcoming High Fidelity VR network calls for full interoperability between different servers, including network-wide recognition of ownership rights.

High Fidelity’s Digital Asset Registry (DAR), is a decentralized, publicly auditable ledger that serves as a record of transactions made by High Fidelity users. Each item is uniquely identified with a digital fingerprint (a hash algorithm) and can be purchased using High Fidelity’s blockchain-based cryptocurrency, the High Fidelity Coin (HFC). The DAR includes tamper-proof PoP services for any asset’s chain of ownership, its characteristics and its entire history, from certification onward.

This approach is designed to solve the theft and counterfeiting problems that plagued Second Life. At the apex of Rosedale’s first VR world’s popularity, thousands of independent developers around the world made a living designing and selling virtual items, and the need for more solid anti-piracy measures was widely felt.

According to High Fidelity, the Bitcoin and Ethereum blockchains have limited throughput (transactions per second) and high transaction fees, which makes them unsuitable for HFC. Therefore, Rosedale’s team opted for a new, public but “permissioned” blockchain.

In a promotional video that predicts a booming future for the VR sector, with a billion users, 50 million servers and a trillion dollar economy, Rosedale explains the design and implementation criteria for High Fidelity’s blockchain.

“As of today, the blockchain is one node using the [Elements] codebase from Blockstream,” said Rosedale. “We’re going to federate it to a managed group of blocksigners and also provide a block explorer and a full read-only node as well, so that we have many backups of the blockchain. This is similar to the [DPoS] (Delegated Proof of Stake) model being used by [EOS] and others for upcoming public blockchains.”

For now, the High Fidelity Commerce system is in closed beta, and High Fidelity is giving HFCs to anyone interested in participating in the beta. Eventually, HFC will be traded on public exchanges like other cryptocurrencies.

“In the coming weeks and months, we will be attaching the HFC blockchain in several ways to the major cryptocurrency networks to enable you to freely trade HFC for other currencies like Bitcoin or Ether, or to use exchange markets to convert it back to real-world currency if you like,” said Rosedale. Considering high price volatility as a roadblock, High Fidelity will try and stabilize the value of HFC at 100 HFC = $1 USD.

Before getting too excited and rushing to buy HFC, it’s worth bearing in mind that Second Life never achieved mass-market appeal, and that could become the fate of High Fidelity as well. However, it can be argued that Second Life was launched too early, and modern VR interfaces, like the headsets and hand controllers developed by Facebook’s Oculus VR, could be the game changer that will permit High Fidelity to succeed where Second Life failed. As always, time will tell.

Crytek

Another VR game developer and technology provider, Crytek, is announcing a partnership with cryptocurrency startup Crycash to create a new cryptocurrency for gamers. Crytek is the maker of the high-performance game development platform CryEngine and publisher of many highly realistic VR games that are popular among hardcore gamers.

“The Crycash ecosystem solves two problems at once: it gives gamers a way to monetize game time by completing in-game tasks, set by game developers, while providing developers with decentralized sales options for games and other virtual items,” said Crycash CEO Wachtang Budagaschwili. “Crycash will consist of four major components: Plink, a communications app for gamers and Crycash wallet; an advertising platform; an eSports platform for gaming tournaments and other events; and a virtual asset marketplace.”

“We see a lot of potential in the Crycash concept, and we were impressed by the Crycash team’s innovative approach to creating practical products and tools for gamers,” said Crytek Managing Director Faruk Yerli.

Crycash will hold a token sale from December 12, 2017, to January 15, 2018, and add Crycash payment options to games from Crytek and other developers.

Munchee ICO Halted by SEC for Securities Violations

Munchee ICO Halted by SEC for Securities Violations

On December 11, the U.S. Securities and Exchange Commision (SEC) issued a cease-and-desist to California-based Munchee Inc. to stop their ICO and return the funds that had been collected.

Munchee had been seeking $15 million in capital to improve their existing mobile app and create a restaurant review ecosystem that they described as being “Yelp meets Instagram” in their Bitcointalk announcement. The problem arose when Munchee emphasized that it would take steps to create a secondary market for the tokens as an investment vehicle, leading investors to have a reasonable belief that their tokens would rise in value, long in advance of the utility of the token being made available.

In the SEC announcement, Stephanie Avakian, co-director of the SEC Enforcement Division, said, “We will continue to scrutinize the market vigilantly for improper offerings that seek to sell securities to the general public without the required registration or exemption. In deciding not to impose a penalty, the Commission recognized that the company stopped the ICO quickly, immediately returned the proceeds before issuing tokens, and cooperated with the investigation.”

In the SEC complaint, the commission argued that the MUN tokens were considered securities because “they were investment contracts” and were deemed a security regardless of their utility at the time of the sale. Munchee consented to the SEC’s order without admitting to, or denying, the findings.

The action is significant as it shows the willingness of the SEC to step in and take action. It also illustrates a willingness on the part of the SEC to work with companies that are cooperative when they run afoul of the regulations.

Bitcoin Futures Are Here: The Story So Far

cboefutures.jpg

The week ahead will give better future indication of Bitcoin derivatives products as yesterday at 6 p.m. EST, the Chicago Board Options Exchange (CBOE) allowed bitcoin futures to begin trading under the symbol “XBT.” Chicago Mercantile Exchange (CME) is set to allow futures trading in the cryptocurrency of their own accord on December 18, 2017. Bitcoin futures were up over 20 percent leading into the U.S. market open. Current appetite for the futures contracts seems to show a stronger preference for near-term bitcoin futures priced above the current spot rate. According to the CBOE twitter feed, over 800 contracts were traded in the first two hours.

At least one outage plagued the CBOE in early trading, including two minutes of downtime from 8:31 p.m. EST to 8:33 p.m. EST, while the CBOE stated at 11:34 p.m. EST that there would be a 5-minute hiatus if the front month (January expiration) rose above 30 percent.

These deliberate halts in trading are known as “circuit breakers” and are meant to protect the market from unmanageable volatility.

While we wait to see how futures trading unfolds in the U.S. markets today, here are some of the notable events that got us into a world of bitcoin futures.

October 31

The CME Group gave bitcoin investors around the world a bit of a Halloween treat when they announced plans to allow bitcoin futures to be traded on their exchange. The Chicago Mercantile Exchange’s announcement notably coincided with the anniversary of the publication of Bitcoin inventor Satoshi Nakomoto’s original 2008 white paper on the cryptocurrency.

Cryptocurrency enthusiasts took this as a signal of mainstream acceptance of the asset class, and bitcoin closed the day (according to historical data provided by www.coinmarketcap.com) at $6,468.40. When futures trading opened last night, bitcoin was trading at $14,901.70.

December 1, 2017

Regulators gave bitcoin futures the green light for the CME Group as well as for self-certification by the CBOE Futures Exchange (CFE) as well as for the Cantor Exchange’s new contract for bitcoin binary options. The exchanges assured the CFTC that the new products were compliant with the self-certification process rules, and the CFTC refrained from halting the self-certification. CFTC Chairman J. Christopher Giancarlo stated in a press release:  

Bitcoin, a virtual currency, is a commodity unlike any the Commission has dealt with in the past…[a]s a result, we have had extensive discussions with the exchanges regarding the proposed contracts, and CME, CFE and Cantor have agreed to significant enhancements to protect customers and maintain orderly markets.

December 4

The CBOE announced it would launch futures trading in bitcoin under the symbol “XBT” on Sunday night, December 10, 2017, at 6 p.m. EST. This move was seen as a manoever to beat the earlier announcement from the competing CME that they would allow futures trading in bitcoin beginning December 18, 2017. Not surprisingly, the CBOE’s usage of the exchange platform Gemini, owned by the Winklevoss twins, may allow the newly minted “Bitcoin Billionaires” to further capitalize on the successes of the cryptocurrencies.

December 5

A Natixis Investment Managers Survey of 500 global investors managing more than $19 trillion of assets has found that “nearly two-thirds [of survey participants] said Bitcoin was in a bubble, and this was a month before the cryptocurrency surged above $10,000 last week.”

Also bearish on bitcoin was Stephen Roach, a Yale University economist who told CNBC’s “The Rundown” that exchange legitimization makes bitcoin “somewhat dangerous [for investors],” citing a “lack of intrinsic underlying economic value to the concept.”

December 6

S3 Partners, a data research and analytics firm, sent this note to investors on GBTC ETF, the only ETF which trades bitcoin. In the note, Managing Director of Predictive Analytics at S3, Ihor Dusaniwsky, suggested that bitcoin as an asset would be “ripe for a pullback once the CBOE futures contracts go live” but also cautioned that the fees for shorting the GBTC ETF will be extremely high. While futures contracts would enable easier and safer access to both long and short positions, Dusaniwsky noted, futures trading would also carry premium costs for all GBTC ETF investors, stating:

Long GBTC holders may feel the pain of its 53% asset premium shrinking, while short sellers will probably be incurring a 50%+ stock borrow fee — both sides will be paying a premium in order to ride the Bitcoin rollercoaster once the CBOE futures start trading.

Also on December 6, 2017, trading volume for BTC nearly doubled from 6.9 billion to 12.7 billion and crosses the 10 billion volume threshold for the first time since Bitcoin crossed $10,000 (November 28, 2017). Whether this run up was related to the prospect of bitcoin futures or just normal market machinations is unclear.

December 7

The Futures Industry Association, an industry organization whose primary members consist of the largest clearing houses and clearing firms for futures in the world, published an open letter it had sent to the CFTC chairman on December 6, 2017, decrying the lack of “a healthy dialogue between regulators, exchanges, clearing houses and the clearing firms who will be absorbing the risk of these volatile, emerging instruments during a default.” This is in spite of the fact that the letter also admits that, “Under law, exchanges may self-certify a product for trading by the close of business one day and then list the product for trading the next day.This process does not require CFTC approval or input…”

Also on December 7, in a joint interview with former Mayor Michael Bloomberg, Chairman and CEO of Goldman Sachs, Lloyd Blankfein, stated that, “We’ll [Goldman Sachs] see. If it works out and it gets more established and it trades like a store value and it doesn't move up and down 20% and there's liquidity in it, we’ll get to it.”

That same interview includes the suggestion that, according to an unnamed source with knowledge of Goldman Sachs plans, the investment bank plans to help clear bitcoin futures contracts for certain clients when the derivatives go live and that “the decision to clear client trades will be made on a case-by-case basis.” Goldman Sachs “will act in an agency capacity” and “won’t serve as a market-maker or build inventory in the derivatives.”

December 8

As the normal trading week came to an end, Coinbase and its exchange platform GDAX sent a reminder from Coinbase CEO, Brian Armstrong, to its users via blog and email to “invest responsibly,” also noting that “there may be downtime which can impact your ability to trade.” While seemingly innocuous, it appears the Coinbase team was preparing for a surge in trading volume that would crash its platform. At 10 p.m. on December 10, 2017, Coinbase tweeted that it would be offline for one hour of scheduled maintenance to “help to prevent slow performance and login issues during larger traffic surges.”

Conclusion

The market on Bitcoin Futures is open for business. After 14 hours of premarket bitcoin futures and a full day of trading from both European and U.S. investors, “XBT” seems to be functioning as planned. While spectators of the past week have foretold of everything from rosy outlooks to apocryphal warnings, we, at least for the moment, seem to be on a path toward embracing cryptocurrency futures as a new wave of derivatives.
