It’s a dumb idea, Even scammer casino allows player to withdraw small amount. They just use the scam card when players manage to win jackpot which is very rare to happened that’s why scammer casino can still get new customers since they do payout.

I think the simple answer to this problem is just play on reputable casino like Duelbits. A legit winnings will always processed quickly. Only those user that involves cheating and abuse suffer an investigation and possible confiscation of their winnings.
