Depending on the casino, i'd have a few solutions, if they automatically convert my balance to USD, I could easily switch to altcoins and pick the one with the lowest minimum. If my only choice is to withdraw in the same coin i've deposited, then I have to top up my balance and clear the deposit rollover or take the risk by playing more.
The important thing is that it is still within a reasonable limit and does not burden players with an increased minimum withdrawal and no congestion in withdrawing funds.
And the option to withdraw from crypto coins may also be adjusted if some Fiat withdrawals are also increased.
There are many more serious problems such as pending withdrawals and not even any confirmations and suddenly scam casinos.
It is important to know the ToS and how the casino provides rules for its users and also based on the recommendations of many users,
if there is a problem, I better not put my money into the casino.
