腾讯科技讯 据外媒报道，随着比特币价格周二继续下滑，有报道称，美国监管机构正在调查，去年比特币创纪录的上涨是否是市场操纵的结果。
According to the foreign media, as bitcoin prices continue to decline on Tuesday, there are reports that US regulators are investigating whether the record increase in bitcoin last year was the result of market manipulation.
彭博社援引三名知情人士的话称，美国司法部正在调查，交易员是否使用了一种存在争议的加密货币Tether来推动比特币价格上涨。Tether的创始人称，这种加密货币由美元以1:1的比例提供支持。
Bloomberg quoted three sources who said that the U.S. Department of Justice was investigating whether traders had used a controversial encrypted currency, Tether, to boost the price of Bitcoin. The founder of Tether said that the encrypt currency was supported by the US dollar in a 1:1.
Tether和Bitfinex没有立即回应CNBC的置评请求。
Tether and Bitfinex did not respond immediately to CNBC's request for comments.
据彭博社报道，联邦检察官今年早些时候对这些加密货币展开了刑事调查。他们现在怀疑，加密交易所Bitfinex的交易员可能是在利用Tether来非法操纵比特币的价格波动。
According to Bloomberg, the federal prosecutor opened a criminal investigation earlier this year into these encrypted currencies. They now suspect that the dealers on the encryption exchange, Bitfinex, may be using Tether to illegally manipulate the price fluctuations of Bitcoin.
去年12月，商品期货交易委员会（CFTC）也传唤了Tether和Bitfinex，部分原因是为了证明这些代币实际上是由美元储备支持的。可能的市场策略包括“欺骗”，或者在价格达到一定水平之前下假订单，然后再撤下这些订单。这两家公司有一批共同的高管。
Last December, the Commodity Futures Trading Commission (CFTC) also summoned Tether and Bitfinex, in part to prove that these tokens were actually supported by dollar reserves. Possible market strategies include “deceiving” or setting false orders before prices reached a certain level, and then withdrawing them.
最近几周，其他美国监管机构也在从各个层面打击加密货币。上周五，美国证券交易委员会（SEC）宣布了对加密货币创始人的首次民事处罚，这是对加密货币行业滥用行为进行广泛监管和法律打击的一部分。
In recent weeks, other U.S. regulators have also been fighting encryption money at various levels. Last Friday, the US Securities and Exchange Commission (SEC) announced its first civil sanction against the founder of encryption money, as part of a broad regulatory and legal response to the abuse of encryption money.
并不是只有监管机构才意识到了Tether对比特币的影响。
It is not only regulators that are aware of the influence of Tether bitcoin.
德克萨斯大学金融学教授约翰格里芬（John Griffin）和研究生阿明沙姆斯（Amin Shams）今年6月发表了一项研究，称比特币涨幅中至少有一半是由于共谋的价格操纵。格里芬在发现金融欺诈方面有10年的记录。
John Griffin, Professor of Finance, University of Texas, and Amin Shams, a graduate student, published a study in June this year, stating that at least half of the Bitcoin increase was due to conspiracy price manipulation. Griffin has a record of 10 years of financial fraud.
在这篇66页的论文中，作者解释说，在比特币价格下跌的关键时刻，人们用Tether来购买比特币，这有助于“稳定和操纵”比特币的价格。
In this 66-page paper, the author explained that at a critical time when bitcoin prices fell, Tether was used to purchase bitcoins, which helped to “stabilize” the price of bitcoins.
虽然Tether的目的是反映1美元的价格，但它的交易价格往往低于1美元。根据CoinmarketCap.com的数据，截至周二，Tether的价格约为98美分。与此同时，比特币周二交易价格接近4745美元，而当天早些时候跌至约4200美元。自接近2万美元的历史高点以来，它的价格已经下跌了75%以上。
Although the purpose of Tether is to reflect the price of $1, its transaction price is often below $1. According to CoinmarkCap.com, the price of Tether as of Tuesday was about 98 cents. Meanwhile, Bitcoin’s trade price was close to $4745 on Tuesday, falling to about $4,200 earlier that day.
