Bitcoin is bound for success.
A year ago I wrote about bitcoin fundamentals vs technical analysis; and how, regardless of the technical aspects, the fundamentals are such a strong force on the overall value of the bitcoin economy; that either bitcoin is going to fail spectacularly or, enjoy incredible success.
I am going to argue that at this point, bitcoin is essentially bound to succeed.
Bitcoin will either reach widespread adoption, fail completely (i.e. become worthless), or retain niche/geek value (like in game currencies).
