Of course it depends on your interest, how much money you do have and your skills in each of these fields!
But these days, except you really have a lot of money to invest in the mining infrastructure, i think the way to go will be Trading bitcoins.
It’s quite possible that even some big, corporate miners found their profit margins under threat from the resulting steep spike in competition. Remember, in mid-2016, Swedish Bitcoin mining firm KnCMiner declared bankruptcy.

The home miner really has no chance to compete in such a challenging environment, unless they have access to free or extremely low-cost electricity…

And many other things can go wrong here like power outages, hardware failures, price crashes (and we see it very often!) etc.
