How do volume, volatility, and returns of Bitcoin vary based on weekday?

Cryptocurrency markets are unique because they are global and open 24/7, which introduces interesting dynamics. 

The regular trading session on the U.S. stock market is 6.5 hours a day — from 9:30 am until 4 pm. But the weekends and holidays are closed so there are normally 252 trading days a year, meaning that the stock market (not including after-market trading) is only open 1,638 hours a year.
