Hello, I have about 3 BTCs that I would like to earn a little bit off of...I tried BTCjam and most lenders didnt pay back, so I made negative there..
I dont know trading so I dont know how that would be... any other ideas?

you should hold your bitcoin just for few months like as 3 or 4 month now bitcoin price is 1600$ and i am sure in coming few 2 or 3 months bitcoin will be reach to 2000$ when you hold hold your bitcoin for 2000$ price you can get 1200$ profit without any risk or other struggle.
Such trade is the same as Bitcoin's investment in this for the long term. But throughout the whole time, Bitcoin's novelties can be different scenarios for the development of crypto currency. So you can find a more suitable time to trade. But is it possible to earn on the difference in the price of Bitcoin, then this is what matters that he needs to devote more or less a lot of time.
