Yeah, but i dont think paypal is interested in joining anything. What its gonna be like is probably owning and dominating it than joining it. Like they own and dominate and abuse and treat unfairly every seller thats ever used them and earned more than $10 through them.
If people wanna play fiat on paypal, fine, theyll get ripped off by paypal left and right on all sorts of high fees and then possibly have their money frozen for 6 months and then possibly having their money stolen by paypal.. if not first stolen by the armies of scammers that use paypal and who paypal loves to award money to in fraudulent sales/chargebacks.
I cant wait for them to start freezing/stealing bitcoins and they freeze someone's 10 bitcoins at $10.000 (worth $100.000) and then 6 months later its $100.000 (worth $1.000.000) and just as the person is about to get his funds released, paypal transfers the bitcoins to themselves claiming acceptable use violations.
I just wonder if the guy kills himself or hurts others at that point.
