比特币继续疯狂，突破3,000美元大关

加密货币比特币继续着惊人的上扬势头，并在上周日下午短暂越过了3,000美元的门槛。

这一数据来自比特币价格指数CoinDesk，尽管其竞争对手CoinMarketCap指数算出的汇率峰值比3,000美元要低上几美分（比特币的价格根据交易平台不同而有所区别，所以不同的公式计算出的汇率也不一样）。

自5月初开始，比特币的汇率就连创新高，当时比特币的价格接近1,400美元。越来越多的人认为，这种加密货币的市场已经出现泡沫。然而在这样的情况下，其价格仍旧一路攀升。

库班在上周二连续发推阐述这种观点。不过在5月的Consensus区块链大会上，这项技术的核心人物针对过度飞涨的比特币价格就已经率先提出了警告。而《财富》的罗伯特•哈克特观察到Token Summit大会预定席位过多，引发与会者厌恶不满时，他认为整个比特币市场都写满了“泡沫”二字。

大部分观察家，包括库班，如今已经接受了区块链技术。这项技术基于股份总账，是在数据安全上的一次前途无量的创新。它在供应链管理到健康数据等各个领域进行资产和信息追踪上，拥有巨大的潜力。不过比特币的价格目前在很大程度上都依托于人们对于比特率普及度提升，未来会有更多创新应用的猜测。对于Ethereum、Dash和Litecoin等与比特币一同崛起的加密货币和区块链系统而言，这一点甚至更加明显。

不过以投机为驱动力的市场，同样也容易受到感情的影响剧烈波动。如果投资者的情绪开始动摇，市场也会迅速动摇，导致比特币价值出现大量缩水。（财富中文网）

The cryptocurrencybitcoin has continued its stunning run-up, briefly surpassing the $3,000 threshold early Sunday afternoon.

That’s according to the CoinDeskBitcoin Price Index, though competing index CoinMarketCap calculated the peak exchange rate at just a few cents short of $3,000 (bitcoin prices vary across exchanges, so different formulas can arrive at different exchange rates.)

The new peak continues a surge that began in earnest in early May, when a bitcoin was worth nearly $1,400. And it flies in the face of a widening consensus that the cryptocurrency market is in a bubble.

That was Mark Cuban’s take last Tuesday, but the technology’s own central figures beat him to the punch by warning about overly inflated prices from the stage at the Consensus blockchain conference in May. And when he saw disgruntled attendees turned away from the overbooked Token Summit conference, Fortune's Robert Hackett saw bubble written all over the bitcoin market.

Most observers, including Cuban, have by now accepted that blockchain technology, a promising innovation in data security based on shared ledgers, has huge potential for tracking assets and information in fields from supply chain management to health records. But the price of bitcoin is currently based in large part on speculation about growing adoption and innovative future applications. That’s even more true for parallel cryptocurrencies and blockchain systems like Ethereum, Dash, and Litecoin, which are mostly rising in tandem with bitcoin.

But a speculation-driven market is also an emotionally fragile market. If sentiment swings, it may swing quickly, and cause a lot of bitcon's value to evaporate.
