Still, BCgame has an option for users to withdraw their fiat deposited balance in USDT. In that case, your account need to be KYC verified and your VIP rank need to be 56 at least.
Any amount, you are required to undergo KYC and need to be at least rank 56? Seems like a little bit requirement for changing your fiat to USDT but valid reason. Since they are using 3rd party service, I'm pretty sure that there's a service fee and if you really don't need crypto I think it's better to stay in fiat, I haven't used this feature yet since I experience like this in other gambling site and I tried to convert my fiat to crypto and the charge is really expensive so it's either I'll just play in crypto or stay in fiat.
I support your expression. It is good to use the currency the gambler deposited to the casino because as you said to convert is costly but it is good for casinos to have conversion free process so that gamblers would not have to spent extra money. I believed B.C game was doing that free before and some other casinos were doing it too.
The gambler can use the default currency. The most important thing in any casino is the smooth deposit (fast) and the smooth withdrawing. And once these are okay they win the public trust.
