At this point it is an idle curiosity. I adopted using PayPal because it was so complicated to do overseas transactions with my dealers and customers. I'm also attracted to the low transaction (for now) fee. And because everything I do is mail order there is no problem with waiting for confirmation. Once learning the basics, it's kinda comforting to see the layers of confirmation. It would seem the inventor was also very smart to keep his true identity a secret as several other crypto currency inventors have been nabbed on dubious charges. It will be interesting to see how it holds up under the onslaught of hackers and gov's. There are still a lot of things I don't understand and to me it's only weakness is having to rely on the net.
