Do u mean credit card fraud? I think, that wont be an issue in your bitcoin venture....
newIndia, I mean all kinds of fraud: rigged games, misprints abuses etc. Every bookie forced to prevent this.
For ex. we have Indian Goa Professional Football League in SportsBook. Or Rwanda National Football League)
But you are right. Fiat financial scammers do 99% of harm.
And it's avoided here with BTC only.
