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.
One and best way of earning bitcoin is to hold and collect while price is quite low and then sell it after when bitcoin price reaches your target. This may be the safest one. Aside from it is to create local business using bitcoin as primary payment option then rotate bitcoin to fiat and vise versa
Holding bitcoins for a profit is what most of us do. But the payment gateway part for your own local businesses is not so appreciated by many government's. They just say "transact in Bitcoins at your own risk.. " so it'll not be preferable.
It's better to convert a part of your savings into Bitcoin and hold them for a long time.
