比特幣價格跌破1萬美元
Bitcoin plunged below $10,000 on Wednesday, marking its worst two-day rout in three years, only hours before the first monthly futures contracts on the controversial cryptocurrency expired.
比特幣價格週三暴跌至1萬美元以下，出現三年來最糟糕的兩日暴跌，而就在幾小時後，這種有爭議的加密貨幣的首批月度期貨合約將到期。The most widely held digital currency has fallen almost a third in the past two days, reducing its total market value to about $165bn, on fears that global regulators will intensify their crackdown on market activity.
由於擔心全球監管機構將加大打擊市場活動的力度，這一持有面最廣的數字貨幣在過去兩天已經跌去近三分之一的價值，使其總市場價值減少至約1650億美元。The falling price was accompanied by record trading on the two Chicago derivatives markets that offer trading in bitcoin futures. About $325m of bitcoin futures changed hands at CME Group and Cboe Global Markets on Tuesday, equivalent to just under 30,000 bitcoins.
伴隨着比特幣價格下降，芝加哥兩家提供比特幣期貨交易的衍生品市場創下交易量紀錄。週二，芝加哥商品交易所集團（CME Group，簡稱芝商所）和芝加哥期權交易所全球市場(Cboe Global Markets)交易了約3.25億美元的比特幣期貨，相當於近3萬枚比特幣。
Both futures contracts were down about 10 per cent in US early afternoon activity on Wednesday.
週三午後的交易中，兩種期貨合約都下跌了約10%。The expiry of the first monthly futures contracts, listed by Cboe Global Markets, will be closely watched as professional investors examine ways to trade the volatile bitcoin and other cryptocurrencies inside the walls of a regulated exchange.
首份月度期貨合約——在芝加哥期權交易所全球市場上市——的到期將受到密切關注，專業投資者將研究如何在受監管的交易所內交易波動劇烈的比特幣和其他加密貨幣。Bitcoin prices have fallen to roughly the same level as early December, when US market regulators allowed futures contracts to be traded. However, some traders expressed doubt that there was a link between the two.
比特幣價格已差不多跌至去年12月初的水平，當時美國監管機構批准了比特幣期貨合約的交易。然而，一些交易商商對這兩者間的聯繫表示懷疑。“I don’t believe there is enough volume or open interest in futures to have any meaningful impact on the spot price of bitcoin,” said Garrett See, chief executive of Chicago-based cryptocurrency trader DV Chain.
芝加哥加密貨幣交易商DV Chain的首席執行官加勒特?西伊(Garrett See)表示：“我不相信期貨市場有足夠的交易量或持倉量，能對比特幣的現貨價格產生任何有意義的影響。”
Settlement of Cboe contracts is based on data collected from the Gemini Exchange. By Wednesday morning on Cboe, 4,431 January-expiry bitcoin futures contracts — of one bitcoin each — had changed hands at $9,780 per contract.
芝加哥期權交易所合約的結算基於從Gemini Exchange收集的數據。截至週三上午，芝加哥期權交易所全球市場交易了4431份1月到期的比特幣期貨合約——每份合約爲1枚比特幣——每份合約價格爲9780美元。That compared with a price per bitcoin immediately on cash exchanges of about $9,421.13. CME, the world’s biggest exchange operator by market value, had traded more than 3,000 contracts on Tuesday. Each CME contract is for five bitcoins.
相比之下，比特幣的實時現金交易價格爲每枚約9421.13美元。芝商所是按市值計全球最大交易所運營商，週二交易逾3000份合約，每份合約爲5枚比特幣。
