英文摘要:
In recent years a new type of tradable assets appeared, generically known as cryptocurrencies. Among them, the most widespread is Bitcoin. Given its novelty, this paper investigates some statistical properties of the Bitcoin market. This study compares Bitcoin and standard currencies dynamics and focuses on the analysis of returns at different time scales. We test the presence of long memory in return time series from 2011 to 2017, using transaction data from one Bitcoin platform. We compute the Hurst exponent by means of the Detrended Fluctuation Analysis method, using a sliding window in order to measure long range dependence. We detect that Hurst exponents changes significantly during the first years of existence of Bitcoin, tending to stabilize in recent times. Additionally, multiscale analysis shows a similar behavior of the Hurst exponent, implying a self-similar process.

中文摘要:
近年来,出现了一种新型的可交易资产,一般称为加密货币。其中,最普遍的是比特币。鉴于其新颖性,本文研究了比特币市场的一些统计特性。本研究比较了比特币和标准货币的动态,重点分析了不同时间尺度下的收益。我们使用一个比特币平台的交易数据,测试2011年至2017年的返回时间序列中是否存在长内存。我们通过去趋势波动分析方法计算赫斯特指数,使用滑动窗口来测量长期相关性。我们发现,在比特币存在的最初几年中,赫斯特指数发生了显著变化,最近趋于稳定。此外,多尺度分析显示了赫斯特指数的类似行为,这意味着一个自相似的过程。
