Fiat does not provide the type of anonymity that crypto does. As long as you're using a site that is reputable you are only battling the house edge.
Fiat casino's doesn't give that anonymity that crypto casinos offer.
Gambling with fiat is okay and it's just a matter of choice on where you think is more suitable to you.Fiat casinos has the tendency to expose the gambler to hoodlums thereby resulting to assault on the street, speaking form experience backed in the year 2000. But the advent of cryptocurrency has given me hope of anonymity while i gamble on casinos without any fear. Personally i prefer to gamble online using cryptocurrency than free gambling in traditional way.
