What is the best way to earn bitcoin aside from signature campaign and bounty campaign...
Is there a legit way to earn bitcoin by investing time and effort only?
I think aside from signature campaign and bounty campaign you can earn bitcoin too using twitter, facebook, etc. But I don't know how to use them to have bitcoin, I saw it in the signature campaign. But if you have enough money to buy bitcoin, I think it is better to buy bitcoin and wait 'til the price of it rise therefore you will have a big profit.
if twitter and facebook is still a bounty program, the question is the way of other than that? the legitimate way that I mean by OP, also I do not really understand, but what I know apart from bounty program we can get bitcoin by trading, and minning
