Demo mode is always different from real games, sometimes casinos make it look more easier and if you’re to deposit and start playing you’ll get a lot of wins but as soon as you start playing you’ll realized that it was nothing like the demo and those 100x you normally see during the demo would disappear all of a sudden and you might even lose your money at 1.05x multiplier.

And as others have mentioned in this thread, using crypto or fiat gives the same effect, the only thing you mentioned that I find valid is the “anonymous” part which is currently being discarded by making players pass through KYC verification. Aside that there’a nothing you’ll get from using just crypto to play.
