I also dont get why they even need a bank statement. I’ve read some people doing this when they were required, but personally i dont remember any casino asking me for bank statement after a win was withheld. Must be that the casino is not really trustworthy, not one of the popular ones in the forum, so they just take advantage of gamblers who dont have much idea about the top crypto casinos.

To prevent that from happening to us, i guess the best option is just stick with the most reputable casinos.
