Chances of winning isnt something  that relies whether you are playing using fiat or crypto. Odds or chances would really be just the same, it is just the difference on payment option or choice you would
be using which there's no point on making out differentiation between the two because its pretty obvious that winning isnt something guaranteed on gambling field. Gambling with fiat we do know does
really require some kyc or your card would be known or simply its not anonymous which is totally contradictory but overall you should not really make yourself believe that they would really be
affecting your winning chance.It doesnt really work on that way and  dont make yourself believe on this one.
