中國帶來的市場恐慌到此為止。周一，比特幣似乎正在消除投資者對(duì)中國政府打壓加密貨幣的不安，實(shí)現(xiàn)了大幅反彈。

截至美國東部時(shí)間上午十點(diǎn)左右的24小時(shí)內(nèi)，比特幣價(jià)格大幅上漲超過10%，在近一周內(nèi)首次突破了4,000美元大關(guān)。

這是一次華麗的命運(yùn)逆轉(zhuǎn)，因?yàn)檫^去一周對(duì)于數(shù)字貨幣而言是糟糕的一周。摩根大通（J.P. Morgan）CEO抨擊比特幣是“欺詐”，另外中國政府命令加密貨幣交易中心停止交易。

這些壞消息導(dǎo)致比特幣價(jià)格大幅下跌到接近3,000美元，比九月初下跌了近40%。比特幣在9月份時(shí)一度突破了5,000美元。

下面是根據(jù)Winkelvoss指數(shù)的數(shù)據(jù)得出的比特幣波動(dòng)情況。該指數(shù)主要統(tǒng)計(jì)多家比特幣交易中心的平均價(jià)格。

So much for those China chills. On Monday, bitcoin appeared to be shaking off investors' anxiety about a cryptocurrency crackdown by the Chinese government, and posting big gains.

As of mid-morning Eastern Time, the price of bitcoin had soared over 10 percent in the last 24 hours and crossed above the $4,000 mark for the first time in nearly a week.

This is a big reversal of fortune after a terrible week for the digital currency in which the CEO of J.P. Morgan (jpm, +1.22%) slammed bitcoin as "a fraud" and the Chinese government ordered cryptocurrency exchanges to cease trading.

The spate of bad news led the price of bitcoin to nosedive to near the $3,000 mark—a nearly 40% drop from early September when it briefly crossed into $5,000 territory.

Here's what the recent ride has looked like, according to data from the Winkelvoss index, which averages the price of several bitcoin exchanges:

現(xiàn)在很難確切地解釋比特幣最新一輪反彈的原因，不過最大的可能是對(duì)加密貨幣彈性的基本信心。中國對(duì)比特幣的打壓，一度被視為對(duì)比特幣生死存亡的威脅，但現(xiàn)在交易商似乎押注比特幣能夠幸存下來，因?yàn)槠渲霸?jīng)遭遇過許多危險(xiǎn)：

也有人提到了最近的一項(xiàng)分析。這項(xiàng)分析支持了一種通俗的說法，即比特幣本身已經(jīng)成為一類永久性資產(chǎn)，可以與貴重金屬相媲美，甚至可以成為央行的一種儲(chǔ)備貨幣：

- Jerry Brito (@jerrybrito) ，2017年9月18日

這種樂觀情緒可能是有根據(jù)的。盡管如此，比特幣從上周的打擊中恢復(fù)過來仍有很長的距離 — 盡管價(jià)格有所反彈，但比特幣仍比其最近的高點(diǎn)低了20%左右。（財(cái)富中文網(wǎng)）

It's hard to say for sure what explains bitcoin's latest resurgence but the best guess may be an underlying confidence in the crypto currency's resiliency. While a crackdown by China might have once seemed to be an existential threat, it appears traders are for now betting that bitcoin will survive this as it has so many previous perils:

The harder nation states crack down, the more coins smart money will buy.

Others pointed to a recent analysis that supports a popular narrative that bitcoin has become a permanent asset class in its own right, one that will jockey with precious metals and may even become a reserve currency for central banks:

This optimism may be well-founded. Nonetheless, bitcoin still has a ways to recover from last week's smackdown—despite the recent rally, the currency is still around 20% below its recent highs. (P.S. If you're bearish on the whole thing: here's our handy guide to shorting bitcoin).
