Read carefully first before responding instead of typing first and then reading after
First , i never said online casinos allow you to withdraw before confirmation
Some online casinos will credit your account on their platform with 0 confirmation ( and since when did crediting your account mean the same thing as send money out?? )
So xyz casino accepts btc as payment option
You send xyz fake 1k btc, casino credits your account with 1k in your xyz casino wallet without any confirmation instantly ( but u can't withdraw)
You use the 1k to play a 50/50 odds game that gets you 2k if you win
If you loose the bet, you loose no real btc , because you sent a fake btc
If you win, you will need to send another real 1k btc which will confirm , so you can withdraw your 2k winnings , because the fake 1k will never confirm and casino won't let you withdraw when your deposit isn't confirmed yet
