Based on what I learned so far mining will provides profits more than trading. However the obstacle is you need some fund to buy and upgrades the machines if you want to profits fast.
If you have more mining hardware then what you said is right. But base on the difficulty today I can say that trading will be more beneficial to all the people that wants to earn better. And mining isn't recommend just for anyone who heard it's a good way of earning. Trading will always be the way of earning good money.
