As i read your thread than i feel that you are only buy the 3 bitcoins because you don't know who to trade and investment. Its mean you have no experience of earning the bitcoin. Therefore i suggest you, be-careful about scam investments sites. Secondly, if you start to trade than use your little amount, don't try to take a big risk. Because you have no experience of trading. And the least, i want to tell you, still hold your bitcoins, everyday bitcoin give you profit on its price, the reason bitcoin price is moving up very fast.
