you should know, not everyone is a fan of cryptocurrency
They could be a gambler with fiat, but using cryptocurrency will make the transaction easier than bank or fiat transfer because they have some limited amount you can send, confirmation transfer if you send a big chunk and how fast transaction. That's why cryptocurrency would be more good than fiat transfer, using them doesn't mean they really love crypto.
If you already play a slot game-based cryptocurrency pair you will be understood, the slot amount is set out for the lowest is 0.1/0.2/0.25. I have some experience miss clicked with this shitty pair using BTC bet 0.25 mBIT. If you really want to bet with estimation crypto, then just calculation the fiat you are betting to crypto you are using, everyone more often using $ pair instance of slot pair for the slot third service.
Not everyone could be fan of crypto, but if you are not fan of crypto then you should not gamble on a crypto website. Stake started here, literally here on bitcointalk, primedice was the start point of it all and Stunna was here every single day promoting his dice website, it was one of the first ones along with just-dice which went with clam and all that chaos so only one left standing was Primedice.
This is why I think it is obvious we should not be moving towards fiat, why? Because it all started in crypto and now that they have taken enough money from crypto people they do not care about our feelings and looking to gather more and more money from fiat world as well? I am sorry but I would not be fine with that, it is as bad as it gets and I rather just let them be with their fiat friends and move to another place that only accepts crypto.
