新年伊始，比特币就因暴涨备受关注，短短一周内，接连突破3万美元、3.5万美元大关。截至1月7日20时，比特币已突破3.8万美元，刷新历史纪录。
At the start of the new year, Bitcoin was receiving attention for surges, breaking the 30,000-$35,000 mark in just one week. By 2000 on 7 January, Bitcoin had broken $38,000, refreshing its historical record.
整个2020年期间，比特币价格一路攀升，从年初的逾7000美元上涨至2.9万美元上方，全年累计涨幅超过300%。
The price of Bitcoin rose all the way throughout 2020, from over $7,000 at the beginning of the year to over $290 million, with a cumulative increase of over 300 per cent over the year.
一度沉寂的比特币，为何再度“沸腾”起来？业内认为，比特币这波暴涨，主要与全球避险情绪有关。
The once-silent bitcoin, why is it “boiling” again? The industry believes that the surge in bitcoin is mainly related to global risk avoidance.
受新冠肺炎疫情影响，2020年以来，全球经济遭遇重创，多国采取超常规货币宽松政策拯救经济，全球通胀预期增强。在高通胀、低增长、负利率的经济环境下，投资者和机构对避险资产的需求大大提升。而基于区块链技术的比特币，具有去中心化、总量有限、可追溯的特点，被认为可以有效避免通货膨胀，受到青睐。
In an economic environment characterized by high inflation, low growth, and negative interest rates, investors and institutions have significantly increased their demand for hedged assets. Bitcoin, based on block-chain technology, is considered to be an effective way to avoid inflation.
从入场者的身份来看，比特币背后的玩家出现新变化，已从早期的以技术员和区块链爱好者等散户为主，变为以全球金融机构为主。巨头机构的入场，给市场带来热度和信心，推动比特币价格上涨。
The players behind Bitcoin, in terms of the identity of the attendees, have changed from an early trend of bulk households, such as technicians and block-chain fans, to a global financial institution. The arrival of giant institutions has brought heat and confidence to the market, pushing the price of Bitcoin up.
比特币价格上涨还和自身特性有关。比特币以区块链作为底层技术，协议数量上限为2100万个。数据显示，截至2020年12月30日，全球比特币的供应量已超1858万个，也就是说尚待“挖掘”的比特币已不足300万个。供应量的减少，加剧了市场惜售行为，进一步推高币值。
The price increase in bitcoin is also related to its own identity. Bitcoin uses the block chain as a bottom-up technology, with an agreed ceiling of 21 million.
“监管不足是催高比特币价格的重要外部因素。”恒大集团首席经济学家任泽平表示，由于世界各国金融市场发育程度、中央政府力量、投资者保守程度等具有较大差异，各国对比特币的监管态度各不相同，而监管不足和立法的相对迟滞为炒作提供了宽松环境。
“Inadequate regulation is an important external factor driving up the price of the high bitcoin.” The Chief Economist of the Sting Group, Xing Zeping, stated that, because of the large differences in the development of financial markets, the power of central government, the conservativeness of investors, etc. around the world, the regulatory attitudes of different countries differ from country to country, and that inadequate regulation and relatively late legislation provide a relaxed environment for speculation.
尽管当前比特币行情呈现“一骑绝尘”态势，但仍有不少业内人士提醒，比特币泡沫大，波动强，风险高，盲目入局甚至加杠杆或出现爆仓危险。
Although the current situation in Bitcoin is one-by-dry, there are still many insiders who caution that bitcoin bubbles are large, volatile, high risk, blind entry even leverage or risk explosion.
1月4日，比特币从约3.3万美元开始暴跌，最低跌至2.8万美元，导致24小时内近10万人爆仓。“缺乏发行主体的比特币几乎是不受控的，很容易受到外界因素影响，这样的不确定性可能会给投资者带来损失。”任泽平说。
On 4 January, Bitcoin began to plunge from about $33,000 to a low of $28,000, causing nearly 100,000 people to explode in 24 hours. “Bitcoin without the issuer is virtually uncontrollable and vulnerable to external factors, and such uncertainty can cause losses to investors.” According to Rin Zeping.
北京邮电大学国家大学科技园金融科技研究所所长、首席区块链经济专家陈晓华表示，比特币价格大涨大落催生了大批交易网站，这些平台的风险不可小觑，“随着越来越多投资者涌入，比特币交易平台高达数十亿元、数百亿元的客户资金缺乏第三方监管，跑路隐患不容忽视”。
Chen Xiaohua, Director of the Institute of Financial Science and Technology of the National University of Post and Telecommunications and chief economic expert on the block chain, stated that the price of Bitcoin had soared and that the risks of those platforms were not negligible, and that “as more and more investors came in, the billions of dollars of money from the Bitcoin trading platform had no third-party supervision and the risk of running the road could not be ignored”.
更重要的是，投资比特币面临监管风险。在我国，对比特币等虚拟货币一直实行严监管。早在2013年12月份，央行等五部委发文指出，比特币并不是真正意义上的货币，不能且不应作为货币在市场上流通使用。2017年9月份，央行等七部委联合发文，要求各类ICO（首次代币发行）立即停止，相关交易平台停止运营。
As early as December 2013, five ministries, including the Central Bank, stated that Bitcoin was not a real currency, and could not and should not be used as a currency in the market. In September 2017, seven ministries, including the Central Bank, issued a joint letter calling for the immediate cessation of all types of ICO (first issue of currency) and the closure of related trading platforms.
目前，比特币交易尚在灰色地带游离，随着未来各国法定数字货币研发及推出，对虚拟货币的管控或打压力度将加大，比特币的投资空间会大大压缩。专家表示，缺少具有公信力的国家或组织为其背书，也没有和任何实物资产挂钩，当主权国家宣布比特币非法时，比特币可能会一文不值。经济日报-中国经济网记者 李华林）
At present, bitcoin transactions are moving away in grey areas, and with the future development and roll-out of national legal digital money, controls or pressure on virtual currency will increase, and bitcoin investment space will be significantly reduced. Experts say that there is a lack of credible countries or organizations to endorse it, nor any physical assets to be associated with it. Bitcoins may be worthless when sovereign states declare Bitcoin illegal.
