Basically you are not gambling with fiat as you do not even deposit with fiat. It is just a unit/denomination of your crypto to be shown in fiat as it gives the best minimum bet amount as pointed out by ryzaadit previously. There were some sites use mBTH/mETH for the 3rd party games but dont you know that most players are not convenience with it then suggest the casino to use $/€ as they can bet lower amount than when the games uses mBTC/mETH. Stake has build their own games that you can play with crypto directly. If you suggest more games, it needs time and effort for them to build their own games. At the moment, Stake is the one with biggest number of original games (16) than other casinos imho. Other may have few original games only.
I still think that it is not cool to show fiat in a crypto place because there are some of us who came here (to crypto) to get away from fiat and here we are talking about how we are gambling in fiat money. I understand that it could be easier, but I do not want to know how many fiat I have, I want to know how much bitcoin I have, that is a much better version.This is why it is not liked by certain people. Don't get me wrong, that is not something bad in the main principle of things, it is not like it would ruin stakes reputation or a shady or scammy thing, it is simply showing fiat how much and that's it, not like it is something very dangerous which is not a problem. This is why some people may "dislike" it but that is not a big deal, it could be acceptable and it could be understandable and there won't be any problems about it like people leaving over it neither, it is something tiny and unimportant.
I just watched what games they played also observe what strategies are used
