Yes, I agree I think we can be freelancer at crypto currency.
Participating in bounty campaign, join IDO or ICO.
always buy when market down and hold it.
I think It's good way to gain income.
Although we should have real job at our real life.
It's not easy , but we should have did research before do that.
Be careful.
