Do you mean trading at localbitcoins? If so, if bitcoin keep climbing, then yes.
I mean selling bitcoin at a profit on the platform and maybe other kind of trade. I don't have checked what is possible but I could also be interested to buy at a profit and maybe trading alt coins. I will check that more in details this week.
So basically making an living based on bitcoin and altcoin trading. Well it's possible, but you have to be good at trading. But you wouldn't be able to this unless you have large enough capital and can afford to lose some at the beginning.
