In a way it can also be a hassle especially for newer traders seeing their investments take a plunge on a dump. But you're right. Trading, with proper knowledge and timing, is one of the best ways to make money. But you half to take it seriously with all the studies and observation you have to make to come.up with a good trade.
I agree with you that it can be a hell of a task for newbies but that's the learning curve they must go through in order to master trading. Everyone at the very beginning made naive decisions and list somehow stupidly but in the end we are all trading with experience now.
In other words, it is always better to have an expert coach than figure it out yourself how to earn more money. It is like in the game of basketball, coach are they for a purpose and if there are no coaches, they will not perform well - it is the same with learning ways to earn more money.
It's just a learning process that takes experience like anything else. You definitely don't always need to be coached. If you have adequate aptitude to learn and put yourself in a learning environment, you'll eventually go from novice to master. Sure you can get a coach, but what's the coaches personal interest? Need to be able to differentiate someone that wants to help you from someone that wants to help themselves.
