I do not think that Bitcoin fail. But I know that I learned new interesting things like new ASCI HW, some of the Linux and some trading skills.
I have a different view of encryption and security now.
All thank`s Bitcoin and people around

The part about Bitcoin failing is more of a thought experiment though. The OP is pretty much asking what you've got out of your Bitcoin experience, which is a pretty interesting premise. I guess I'll go with the generic response and say that I got an enthusiasm in investing, but I would never really want an investment job on Wallstreet.
