科学美国人60秒 比特币有多流行

（单词翻译）

There are now more than 16 million bitcoins in circulation, with a total market cap of 130 billion dollars—more than the market value of Netflix, Priceline or Starbucks. Just going by numbers, bitcoin is the one coin to rule them all.

现在流通的比特币有1600多万，总共市场价值超过1300亿美元——这比Netflix、Priceline和星巴克的市场价都要高。只从数量来说，比特币可以控制所有的货币。

But if you consider the spectrum¹ of 600 actively² traded cryptocoins as a financial ecosystem…you can take an evolutionary³ approach, and ask: which is the 'fittest' of the coins?

但是，你把600个活跃的货币作为一个金融系统来说……你可以采取循序渐进的办法，然后询问：哪一种货币最合适呢?

Or, in other words: "Every cryptocurrency, bitcoin, ethereum, there are many…are a different species." Andrea Baronchelli, a network scientist at City, University of London.

换句话说，“每一个加密货币，比特币，以太坊，都有很多……是一个不同的品种。”Andrea Baronchelli，是伦敦大学的网络科学家。

He and his team used evolutionary models to approximate the real-world behavior of cryptocurrencies. Each week of currency trading was treated as a new generation of progeny⁴. Reporting their results in the journal Royal Society Open Science, they found that a so-called 'neutral' model of evolution best explained coin behavior…meaning no coin had a selective advantage.

他和团队使用进化模型来模拟真实世界的密码货币。每一周的货币交易都被看做新一代的衍生品。该研究结果发表在《皇家学会开放科学》杂志上。他们发现，所谓的“中性”进化模型最好解释了硬币的行为，也就是说，没有一枚硬币有选择性的优势。

Which implies that: "Investors⁵ choose which cryptocurrencies to invest in only proportional to the cryptocurrency's market share, and nothing else. So they are not apparently⁶ considering other fundamentals like the underlying⁷ technology or the purpose for which a certain cryptocurrency has been designed for. They are just sampling the market, sampling each cryptocurrency proportional to its market share."

这意味着“投资者选择与市场份额成正比的加密货币投资，没有考虑其他因素。所以，他们似乎并没有考虑其他的基本面因素，比如基础技术，或者某个加密货币的目的是什么。只是对市场进行采样，对每一种加密货币的市场份额进行抽样。

And only when investors begin to value coins for a particular attribute—such as their convenience or their intrinsic technological⁸ advantages—will the market start to actively pick winners.

只有当投资者开始以某种特定的属性——比如货币的便利性或其内在的技术优势——来评估硬币时，市场才会开始积极地挑选赢家。
