How could one compare mining with trading?? It is two different fields required different skills and different character. Also mining is not as profitable as it was not a long time ago. Anyway it is less risky than trading, so if you want to figure what it is - good decision
Nowadays its hard to understand what is more profitable and what is less.
Do what you like best and what you can do. For mining, you need a large starting investment. You can start trading with a minimum amount of investment.
