My worst mistake was undoubtedly to join this great alt economy too late, when price has achieved the $400 and it is too expensive to buy bitcoins with my own money, despite I had the opportunity to join this ecosystem early, several years ago but I missed that opportunity.
Yeah me too felt a lot that I had missed the great opportunity of working with bitcoin several years before. Even more people are there who were not aware of bitcoin even now, comparing with them I feel I am lucky.
