LongHash compared CoinMetrics' daily bitcoin price data with the daily closing price of the Dow Jones Industrial Average (DJIA). From 2010 to March 2020, the correlation coefficient between the two exceeded 0.84, indicating a strong positive correlation. However, if the data is broken down by year, the correlation is more ambiguous. For example, in 2017, the two had a strong positive correlation of 0.90; 2012, 2013, and 2019 all showed a moderate positive correlation of about 0.5; the correlations in 2011, 2015, and 2018 were close to zero. Bitcoin seems to be a safe haven for some traditional market activity, although it is not entirely reliable. Data show that over the years, Bitcoin has occasionally become an effective alternative to traditional markets.
