Abstract

In this study, the multifractal cross-correlations characteristics and coupling coordination between Fintch, global technology, and bitcoin markets are investigated. The empirical results illustrate that the cross-correlations between returns of these markets are multifractal. The multifractal characteristics and multifractal causes analysis illustrated that the apparent and intrinsic multifractal cross-correlations between the return pairs of global technology and bitcoin markets present stronger features. The evolution analysis shows that the volatility of multifractal features between return pairs of Fintech and global technology markets is stronger. Most of the return pairs of these markets are at the level of coordination.
