You are lucky if you got into bitcoin business back then because at that time, the prices of bitcoin were very low. This digital currency was in early stages of development whereas at present, bitcoin is the leader of all digital currencies and has successfully beaten gold in being the most expensive and profitable investment. I wish I knew about bitcoin five years ago, anyways many people still dont know about it.
