Recently, I've been trading bitcoins on btc-e, earning only a little, yes, very little, except the fees that btc-e takes.
Besides trading, are there any good method to earn bitcoins? Thanks.
The best way after trading would be investing.
Suggesting just the word 'investment' is not sufficient. It would be dangerous for someone who will go to any scammers way to invest with them. You have to explain about the types of investment that which type of investment is better for to invest to stay away from scammers and to earn a high profit.
