It would have been great if the Op has stated from the beginning that the pic wasn't his and not waited to have received correction before noticing his mistake. That means he would have left it there has it not been discovered as a lie, right? Anyway, I guess the lesson the Op is trying to let on is that patience is rewarding. Who would have thought that a $50 investment could yield one such a massive profit? I for one would have doubted my ability to hold for that long or the fact that Bitcoin price could rise to the level it is now.
Notwithstanding, congratulations to the real owner and this is just a reminder that investing in Bitcoin is not for the weak and doubtful minds.
