Which brings us to an interesting question... how long does something have to go before we consider it a success even if it fails later? When something comes along to defeat Facebook, are we going to call Facebook a failure? Was Myspace a failure?[1] The fact that Bitcoin has ran this long, given some huge payouts and legit(albeit small) businesses accept it as payment, I'm almost ready to call bitcoin a success even if it fails 6 months from now.
