In the research, the causal relationships between Bitcoin, gold and oil prices were examined. The data of the research covers the period from 2015 to July 2020 and consists of daily price values. Augmented Dickey-Fuller Unit Root Test was used to see whether the stochastic process changes with time. Bitcoin and gold series do not contain a unit root since the oil series is stationary at the level while the difference is stationary. The reason why the series containing unit roots are not stationary is due to structural breaks or not, was investigated by Bai-Perron Unit Root Test with Multiple Structural Breaks. According to the test, it was determined that the Bitcoin series has one break and two regimes, while the gold series has two structural breaks and three different regimes. Whether the research series are cointegrated or not was investigated with the Gregory and Hansen test. The causality between the series was examined with the Toda-Yamamoto causality test, which is based on the VAR (Vector Autoregression) model and examines the causality in the series regardless of the unit root. A two-way causality relationship was determined between the eight lag-long Gold series and the Bitcoin series. In other cases, a causal relationship has not been established. As a result, we give an evidence that Bitcoin and gold prices series followed a parallel pattern while with oil not. Therefore, investors can add Bitcoin into their portfolios to make balance of the risk and return.

比特币与一些传统资产的相互关系

在研究中,研究了比特币、黄金和油价之间的因果关系。研究数据涵盖 2015 年至 2020 年 7 月期间,包括每日价格值。增强的 Dickey-Fuller 单位根检验用于查看随机过程是否随时间变化。比特币和黄金系列不包含单位根,因为石油系列在水平上是固定的,而差异是固定的。包含单位根的序列不平稳的原因是由于结构断裂还是非结构断裂,通过具有多个结构断裂的Bai-Perron单位根检验进行了研究。经测试,确定比特币系列一断二治,黄金系列二结构断三不同。研究系列是否协整通过 Gregory 和 Hansen 检验进行调查。使用基于 VAR(向量自回归)模型的 Toda-Yamamoto 因果关系检验检查系列之间的因果关系,并检查系列中的因果关系,而不考虑单位根。确定了八个滞后的黄金系列和比特币系列之间的双向因果关系。在其他情况下,因果关系尚未确定。因此,我们提供证据表明比特币和黄金价格序列遵循平行模式,而石油则没有。因此,投资者可以将比特币添加到他们的投资组合中,以平衡风险和回报。它基于 VAR(向量自回归)模型,并检查序列中的因果关系,而不考虑单位根。确定了八个滞后的黄金系列和比特币系列之间的双向因果关系。在其他情况下,因果关系尚未确定。因此,我们提供证据表明比特币和黄金价格序列遵循平行模式,而石油则没有。因此,投资者可以将比特币添加到他们的投资组合中,以平衡风险和回报。它基于 VAR(向量自回归)模型,并检查序列中的因果关系,而不考虑单位根。确定了八个滞后的黄金系列和比特币系列之间的双向因果关系。在其他情况下,因果关系尚未确定。因此,我们提供证据表明比特币和黄金价格序列遵循平行模式,而石油则没有。因此,投资者可以将比特币添加到他们的投资组合中,以平衡风险和回报。我们提供证据表明比特币和黄金价格序列遵循平行模式,而石油则没有。因此,投资者可以将比特币添加到他们的投资组合中,以平衡风险和回报。我们提供证据表明比特币和黄金价格序列遵循平行模式,而石油则没有。因此,投资者可以将比特币添加到他们的投资组合中,以平衡风险和回报。
