英文摘要:
This letter revisits the informational efficiency of the Bitcoin market. In particular we analyze the time-varying behavior of long memory of returns on Bitcoin and volatility 2011 until 2017, using the Hurst exponent. Our results are twofold. First, R/S method is prone to detect long memory, whereas DFA method can discriminate more precisely variations in informational efficiency across time. Second, daily returns exhibit persistent behavior in the first half of the period under study, whereas its behavior is more informational efficient since 2014. Finally, price volatility, measured as the logarithmic difference between intraday high and low prices exhibits long memory during all the period. This reflects a different underlying dynamic process generating the prices and volatility.

中文摘要:
这封信重新审视了比特币市场的信息效率。特别是,我们使用赫斯特指数分析了2011年至2017年比特币长期记忆收益率和波动率的时变行为。我们的结果是双重的。首先,R/S方法易于检测长内存,而DFA方法可以更精确地区分信息效率随时间的变化。其次,日收益率在研究期的上半年表现出持续性行为,而其行为自2014年以来更具信息效率。最后,价格波动率,以日内高价格和低价格之间的对数差来衡量,在整个期间表现出长记忆。这反映了产生价格和波动性的不同基本动态过程。
