Paycoin is a pointless clone wrapped in a blanket of scam, but there are alt coins that are innovative. Bitcoin will fade for the same reasons that first-generation technologies always fade. The sooner the better.
Yep, just like those ridiculous ground cars faded quickly after flying cars came along.
I haven't seen practical flying cars yet, but I've seen lots of other first-generation technologies be displaced by competitors that offered real innovations. It's inevitable.
