I think what your talking about is speculating vs investing - the term Benjamin Garnham uses.
Speculative trading is not investing.
Professional trading, esp with leverage, is extraordinarily difficult to gain the required mentality, discipline, knowledge, and skills be consistently profitable. The common saying is that 90% fail, I believe it's higher, perhaps much higher. Learning trading was the most difficult thing I've done in my life. It's hard in a way most people don't grasp.
