Yeah, no. Bitcoin eliminates chargeback fraud by completely eliminating the whole idea of chargebacks. You can tell your customers that if they don't get what they paid for and you don't feel like helping them, then they're basically screwed.

People here are talking about losing double-digit percentages of their purchases from Paypal forcing users to create a Paypal account, which takes like 30 seconds.
