Well for me, I'd sometimes used fiat in our local especially during fiestas. There is no casino in our place to play, only our chance to put some bets by visiting gambling site which I've sometimes been doing right now but it doesn't mean that I'm addicted into this.
I usually use fiat money before in sport betting against my coworkers especially from Basketball from a minimum of $10 every game and just for fun but as I discovered crypto and gambling sites I realized its more easy to use and more fast processing if you want to cash out your money from winnings and the best thing is even you stuck on traffic outside you can easily gamble your money converted crypto using your smartphone anytime, anywhere as long as you can access online gambling sites.
Yet to find it more comfortable than visiting offline casinos and it makes people become addicted. It is much easier to use crypto than fiat today when using online casinos but I'd like to think that it has also a bad result and that is by losing a lot.
