关于比特币的相关程式化事实:波动,第一回报概率和自然现象

Relevant Stylized Facts About Bitcoin: Fluctuations, First Return Probability, and Natural Phenomena

C. R. da Cunha, R. da Silva

摘要:

比特币是一种数字金融资产,没有中央权威。这使得它在许多方面与传统的金融资产不同。例如,令牌的总数是有限的,并且它没有明确的使用价值。尽管如此,人们对它是否遵循传统金融资产中的程式化事实知之甚少。在这里,我们测试了比特币的一组这些程式化的事实,并得出结论,它的统计行为与大多数其他资产一样。例如,它表现出聚合高斯性和波动缩放。此外,我们通过与自然发生的地震进行类比,证明比特币同时遵守大森定律和古腾堡-里克特定律。最后,我们证明了自旋系统的全局持续性,呈现出类似于股票市场的指数幂律行为。

英文摘要:

Bitcoin is a digital financial asset that is devoid of a central authority. This makes it distinct from traditional financial assets in a number of ways. For instance, the total number of tokens is limited and it has not explicit use value. Nonetheless, little is know whether it obeys the same stylized facts found in traditional financial assets. Here we test bitcoin for a set of these stylized facts and conclude that it behaves statistically as most of other assets. For instance, it exhibits aggregational Gaussianity and fluctuation scaling. Moreover, we show by an analogy with natural occurring quakes that bitcoin obeys both the Omori and Gutenberg-Richter laws. Finally, we show that the global persistence, originally defined for spin systems, presents a power law behavior with exponent similar to that found in stock markets.
