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

目前在流通的比特币数量超过1600万，总市值达1300亿美元——这比奈飞公司、旅游网站旅游网站和星巴克公司的市值都要高。只从数量来说，比特币可以统治所有货币。

But if you consider the spectrum¹ of 600 actively² traded cryptocoins as a financialecosystem...you can take an evolutionary³ approach, and ask: which is the 'fittest' of thecoins?

但是，如果将600种交易活跃加密货币当作一个金融系统来看，那你可以采取渐进的方式，并询问：哪种货币最好?

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

或者换句话说，“加密货币、比特币、以太坊等等，很多不同种类的虚拟货币都在流通。”伦敦大学的网络科学家安德里亚?巴伦凯利说道。

He and his team used evolutionary models to approximate the real-world behavior ofcryptocurrencies. 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.

他和团队使用演化模型来模拟加密货币在真实世界的行为。每周的货币交易都被视为新一代的产生。他们将研究结果发表在《英国皇家学会学报·开放科学》期刊上，他们发现，所谓的“中立”演化模型对货币的行为进行了最好的解释，这说明没有货币有选择优势。

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

这也暗示着：“投资者选择哪种加密货币进行投资，只与加密货币的市场份额成正比，与其他无关。所以，显然他们并没有考虑其他基本因素，比如基本技术或某种加密货币的设计目的等。他们只是对每种加密货币的市场占有率进行抽样。”

And only when investors begin to value coins for a particular attribute—such as theirconvenience or their intrinsic technological⁸ advantages—will the market start to actively pickwinners.Thanks for listening for Scientific American — 60-Second Science Science.

只有当投资者开始重视货币的特定属性——比如货币的便利性或其内在的技术优势——市场才会开始积极地挑选赢家。
