If you're going to force me to choose between both, I'd just attempt to get good at trading. With bounties (outside of signature campaigns), you're just going to get useless tokens most of the time. But with trading, you can definitely make good money if you actually get good; but that's a huge if. The bad thing about trading though, is that you could simply end up with actually less money than when you started.

For me, I'd do something else besides both. Quick reminder that you can also make money outside of the cryptocurrency space.
