Personally, I like to gamble with crypto not only because it's "KYC-free", but also because it represents freedom. The only downside is market volatility. Stablecoins always have their value pegged to Fiat (usually the USD), but they're too centralized and often lack investor protections or guarantees of any kind. And then there's the choice of Fiat, but most (if not all) casinos or gambling sites require you to reveal your personal ID (KYC) to use them. In some countries it's even illegal to gamble online. So crypto for me, is the true winner here.
How about you?
It's a combination for me, if I go online, then I will used crypto's, seldom to I play with fiat unless it's necessary. But things have evolved lately, as we all know that Bitcoin fees in the last year or so are not that cheap so enter LTC or Doge as options as they are very quick.
However, if we and my friends play, we go to traditional based so I also enjoyed playing outside. With the atmosphere or the settings, with free drink, and then there is entertainment with the bunch of guys you know for so long. And then at the end of the day, you got drunk, lost money but enjoy that night.
