摘要

我们使用 Kraken 交易所的日内交易数据，计算了 2018 年 2 月至 2022 年 12 月期间比特币和以太币的每日价格同步性。然后，我们利用christalblockchain.com提供的综合报告来研究黑客攻击对这两种顶级加密货币之间价格同步性的影响。我们的研究结果表明，以已实现相关性衡量的价格同步性在整个样本期间始终为正，只有一个例外（负值）。我们进一步发现，黑客攻击事件与比特币和以太币的未来价格同步性之间存在正相关关系。这一结果在使用其他价格同步性衡量标准时也是稳健的。

Hacks and the price synchronicity of bitcoin and ether

We use intraday trading data from the Kraken exchange to calculate the daily price synchronicity of Bitcoin and Ether from February 2018 to December 2022. We then use a comprehensive report provided by christalblockchain.com to investigate the impact of hacks on price synchronicity between the top two cryptocurrencies. Our results show that price synchronicity, as measured by the realized correlation, is consistently positive throughout the sample period, with only one (negative) exception. We further uncover a positive relationship between hacking events and the future price synchronicity of Bitcoin and Ether. This result is robust to an alternative price synchronicity measure.
