The fraud part I was discussing is specifically that criminals or even central authorities can't create additional supply (think printing cash) because they can only be created through the mechanism of the crypto itself. Things like bank runs or runaway inflation due to poor govt policy. I didn't mean scams weren't possible, I guess I apologize for not being more clear, but I figured because we specifically talked about bank runs and supply that you understood what I was talking about.

It would be insane to say crypto prevents all forms of fraud, so I didn't think it'd be taken that way. But you don't know me so I shouldn't make those assumptions when talking to randos online lol.
