It all depends, how much money you got and how would you more like to earn money. By mining you earn your money passively, i mean you do not have to do anything while your computer is mining and make you money. But that solution is really hard and does not pay off, unless you invest a lot of money. But on the other hand there is trading, which is by my opinion better. You can start with less and move forward from there. At the end its your choice.
