The volatility of BTC has been extremely low for a few weeks now. Even to such low levels, which have only occurred three times in recorded history.
The first time this happened was a few days prior to the final sell-off of 2018, which caused BTC's price to drop by 50% and ultimately resulted in the bear market's final bottom.
The second time this occurred, in the summer of 2020, a 35% bull rise marked the beginning of the most recent crypto bull-market.
