I don't think they decided to leave the crypto market. At this stage of the crypto market, only the smartest investors remain here who understand perfectly - after such a major fall, the market will in any case restore its position. Therefore, in any case, they will return when the first prerequisites for a rise in price of cryptocurrency appear.
It's ironic that they'll come back here after the market recovers and will buy with the current price. They don't know how to utilize the bear trend. Though we can't blame them for leaving, maybe they've easily swayed by fuds or they just cut loss, whatever their reason they'll be the one who will take the consequences.
