Ofcourse mining and trading is not the same. Mining is like investing, it takes very long time to earn big profit in mining, in trading, it is a reciprocal process, you exchange your asset to someone's asset. I think it is easier to earn in mining because you will only need to wait for the profit unlike in trading, you gonna need some skills like, timing and you need not to let your emotion dictate you what to do, but the good thing in tradig is that you can have bigger profit in shorter time of period.
