No problem whatsoever for me in the casinos that I have played, withdrawal as smooth, although I will say that in the last couple of months or even last year we have problems when the mempool was congested and the fees to withdraw as so high, nevertheless it was not a problem with the casinos itself.

Not to burst the bubble for those who are having problems, maybe they don't read the ToS, or maybe they have to many accounts on one casino that they might be flagged down by it multi-account that will cause them to have problems with withdrawals specially if they win big.

Main issue though is that majority of us are really into gambling and we might not see ourselves are addicts or turning to be one because it's really hard to control it.
