Figure 7.

Minimal spanning trees (MSTs) calculated based on the q-dependent detrended correlation coefficient $\rho (q,s)$ for the exchange rates of a form X/BTC, where X stands for one of 128 cryptocurrencies traded on Binance [21]. Each node is labeled by the corresponding cryptocurrency ticker. All trees correspond to $q=4$. On the left there are MSTs obtained for $s=10$ min, while on the right there MSTs obtained for $s=360$ min. Each row shows MSTs calculated in a different period (a 7-day-long moving window with a step of 1 day): January 2019 (top), July 2019 (middle), and March 2020 (bottom).
