Dodgy PayPal stuff aside. PayPal works because it's user friendly, even my technically inept parents can use it. And its integrated into so many online places as a payment method. If Mutiny can have a system that's that kinda user friendly easy to operate. Huuuuuge deal. BTC generally has this narrative around it that it's too much hard work to use, get a way that even the most clueless can understand and your onto a winner.
