No, I don't think so. If bitcoin failed as a currency why every people talking about it, why it is so famous. I think it is very successful.
Bitcoin sure is famous and to some extent it is successful. Not just successful, it is very successful. BUT, you should realize by now that Bitcoin is not successful as a coin. People all over the world is using BTC but none of them use it as a currency. We might use it as a currency in the long run but I don't think it's going to happen any time soon.
