for who know about bitcoin, yes bitcoin already succeeded but what the problom right now is many people still dont know about bitcoin or some people know but their worry if using bitcoin, their bitcoin can stolen by hacker
for me bitcoin not succeeded
i think you didn't understand the OP, bitcoin has succeeded simply because is still alive and kicking some ass, the rest is just fud and no-sense
actually despite all the fud bitcoin is still here, hence it mean that his success is even more affirmed
