Many had failed and blame themselves, and even regretting because of the wrong decision been made. Yeah, this is very common for those people who come in a hurry. It was found to be more relevant to anticipate the market decline than to be a greedy holder looking for more profit. Likely, if you miss the chance of selling your coins to Bitcoin, I'm very certain you are also doing this (blaming).

You are not just doing it smart, but what you did is an independent decision, and it was great.
