Usually its just before weekend or after weekend market will have a big move. When weekend its usually quieter, i think its because of many trader are stock player and follow the worktime.
Mostly, when weekends, the price plummets and that's what you'll get to analyze.
In crypto, I don't think that there's a relation between the weekdays and weekends of crypto and stocks. But we've seen the connection of drops and pumps from stocks to crypto.
The market itself has connections for sometimes but not entirely including the days when traders are trading.
