Anonymity and popularity of Cryptocurrency are two of it's the best attraction.
And Cryptocurrency games are more transparent.
Will, there comes a time that all online gambling sites will be Cryptocurrency based?
Still, there are people that tend to use fiat than cryptocurrency and I am one of them. I can earn fiat easily than crypto so I am giving so much importance to my crypto. On the other side, crypto goes up and down. If it goes up I will surely regret that I used it especially if I lose the game.
Player like you will be one of the reasons why most online casinos will still have fiat on their options. And I don't think they will go in crypto full blast anytime soon. For some players, playing fiat has advantages on them like they don't have to worry about volatility. But for some players who want anonymity, they will go for online casinos that don't require KYC. But online casinos with fiat will be here long time just like traditional physical casinos.
