Skew data shows that, in terms of the annual return of macro assets, BTC is currently far ahead of other assets, such as gold, the S & P 500 index (SP 500), the US dollar and the WTI crude oil commodity index. At the same time, there is a clear divergence between the BTC and the S & P 500 Index, which was formed last week. As the price of bitcoin rises slowly, the S & P index is declining. For US 10Y (10-year U.S. Treasury bond), the same divergence began in December 2019. However, since the beginning of 2020, the annual return of US 10Y has fallen from 1.9% to 1.6%. At the same time, Bitcoin has increased by 34%. Even the Dow Jones Industrial Stock Price Index (DJI) has an annual return of only 1.18%, which is difficult to maintain. This shows that Bitcoin is not related to many assets.
