Some gambling sites do require you to do a KYC before withdrawal of a huge amount. But this is rare and most of the times there is some sort of discrepancy involved or the person may have used fraudulent ways to get the money.

This statement is spoken too much without proof. Online gambling is still majorly owned by the fiat casinos and not crypto casinos. You should try to find proper sources to refute my point.

Even fiat casinos provide many benefits to the player.
