芝加哥商品交易所（CME）比特币 (BTC) 衍生品交易本月似乎将达到创纪录水平，交易量飙升，未平仓合约已在历史高点附近徘徊。CME Group 数据显示，截至 1 月 16 日，仅 CME 期货产品的未平仓合约就总计 5328 份，合 26640 枚比特币（约合 2.37 亿美元）。该数字比芝加哥商品交易所自 2017 年 12 月推出以来的任何月度收盘价都要高，截至目前，2019 年 7 月的 5252 份合约居于历史高位。而根据美国商品期货交易委员会 (CFTC) 1 月 7 日公布的最新数据，未平仓合约数量在 1 月初确实超过了目前的水平，达到约 5400 份。
Bitcoin (BTC) derivatives trading looks set to reach record levels this month as volume spikes and open interest hovers near all-time highs.
Data from CME Group shows that as of Jan. 16, open interest for its futures products alone totaled 5,328 contracts — or 26,640 BTC ($237 million).
Open interest on track for record
The figure is higher than any monthly close CME has seen since it debuted in December 2017, with July 2019 currently in the lead with 5,252 contracts.
Open interest did surpass current levels earlier in January, reaching around 5,400 according to the latest data from United States regulator the Commodity Futures Trading Commission, or CFTC, published on Jan. 7.
As Cointelegraph reported, futures offerings have received significant attention from both investors and commentators as new participants appeared to fuel a Bitcoin price rise in 2020.
区块链仲裁公司 Proof of Trust 计划在伦敦证券交易所上市
区块链仲裁公司 Proof of Trust 计划在伦敦证券交易所上市，但目前该公司尚未公布更多有关上市的详细信息。据悉，该公司致力于开发区块链智能合约纠纷解决方案。
As reported Friday by Alliance News (via London South East), The Proof of Trust aims to float on the LSE's Main Market.
"We at The Proof of Trust are excited at the prospect of a full listing on the main market of the company's shares and we look forward to providing investors with the opportunity to share in this groundbreaking project," said lawyer and Proof of Trust CEO Dean Armstrong.
Targeting the Main Market would seem ambitious for a young firm working with blockchain, as it is generally reserved for larger companies with a proven track record and sets a higher threshold of requirements for listing. Smaller and newer firms more often attempt to float on the exchange's Alternative Investment Market (AIM).
CoinDesk has reached out to the company for more details on the planned listing.
Proof of Trust says on its website that it has built a protocol using distributed consensus to "manage arbitration or dispute resolution for smart contracts."
Its "anti-collusion algorithm" is said to validate the authenticity of data with "trusted and verified experts" before it is recorded on the blockchain and used to execute smart contracts.
预测：到 2025 年硬件钱包市场规模将达到 7.08 亿美元 ?!
1 月 17 日消息，市场研究公司 Mordor Intelligence 近日下调了其对硬件钱包市场的增长预测，但下调之后的预测数据显示，硬件钱包市场增长规模仍是当前规模的 4 倍以上，到 2025 年硬件钱包市场规模将达到 7.08 亿美元。Mordor Intelligence 公司预测称，到 2019 年，硬件钱包市场的价值为 1.619 亿美元，且该市场在五年内的复合年增长率（CAGR）为 24.93％，在未来五年内可能高达 7.0837 亿美元。
It seems that Mordor Intelligence, a market research company, downgraded its hardware wallet market growth forecast, while the market is still expected to grow more than 4 times its current size and reach USD 708 million by 2025.
Now, the company says that in 2019, the hardware wallet market was valued at USD 164.19 million, and it may go as high as USD 708.37 million in five years at a compound annual growth rate (CAGR) of 24.93% over the forecast period from 2020 to 2025.
A year ago, Mordor Intelligence estimated that the global hardware wallet market was valued at USD 227.5 million in 2017 and is expected to reach a value of USD 1.6 billion by 2023, at a CAGR of 36.6%.
The numbers are smaller all across the board. The hardware market was valued at 28% less in 2019 than in 2017. The predicted CAGR is 12% smaller, while the most prominent difference is that in the expected value: from USD 1.6 billion until 2023 to USD 708.37 million until 2025, which is 56% drop, in addition to two years more in the forecast period.
Also, last year's report said that by 2023, USB type of hardware wallet is expected to hold the highest market share by type and to reach a value of USD 1.31 billion.

Bitcoin Suisse CEO：比特币减半将推动整个加密货币市场上涨
瑞士加密金融服务提供商 Bitcoin Suisse 首席执行官 Arthur Vayloyan 表示，比特币减半将推动整个加密货币市场上涨。尽管许多投资者因比特币未能重获历史高位而感到沮丧，但加密领域正在发生许多积极的事，今年还会看到这些事发生，网络扩展还将继续。即将到来的比特币减半会推动比特币价格上涨。
Bitcoin Suisse CEO, Arthur Vayloyan sets out a bullish expectation for cryptocurrency in 2020. And while many investors are feeling a sense of frustration over Bitcoin’s failure to recapture the all-time high, Vayloyan reminds us that many positive developments are occurring in the background, which will likely add to upside pressure. Not forgetting Bitcoin’s halving in May.
In a CNN interview, Vayloyan talks about his expectations for cryptocurrency in the coming year. And he is extremely positive based on the level of development and research that has come to typify this industry.
“People sometimes think when they don’t see stellar price increases etc., that nothing happens. But so many things happen, and we’re going to see them also this year emerging. And with that interest and network expansion will just continue.”
With that, Vayloyan believes this will compound to push cryptocurrency prices upwards. But more so, he also drew attention to the coming Bitcoin halving, which he sees as adding to positive price pressure.

法官裁定美国税局对 Coinbase 用户调查只覆盖 2016 年
今日消息，美国地方法官 Sallie Kim 裁定美国税局对 Coinbase 用户 William Zietzke 的加密税务调查只覆盖 2016 年。法院认为，就时间而言，国税局要求索取的信息过于宽泛，并建议国税局提出一份修改过的传票以限制信息的时限，以便将重点放在相关交易上。此前 2019 年 11 月消息，William Zietzke 在对美国国税局调查其 Bitstamp 帐户的诉讼中败诉。
According to Law360, U.S. Magistrate Judge Sallie Kim says the IRS should reduce the scope of its document request to Coinbase concerning one of its users — Zietzke. Delivering the court’s recommendation, Judge Kim stated:
The court finds that the requests for information are overbroad with respect to time, and the court recommends that the IRS propose an amended summons to limit the time frame of information sought to focus on the transactions at issue.
The document request is also part of the tax agency’s investigation into Zietzke after he reportedly reduced his 2016 crypto tax filing from $104,482 to $410.
Zietzke’s crypto tax filing reduction earned him a $15,000 refund which prompted an IRS investigation. According to Zietzke, the reduction was because two of his largest crypto transactions did not occur in 2016.
