Don't you think that if a beginner starts investing and later on switch to trading no matter the little amount, it will get to a time where he can choose to gamble all the money he has invested just for trading of which if he loses, what will be the essence of making investment at first because it's just like throwing away the water you have in your bowl while expecting a rain to fall and in the end the rain didn't fall again. Beginners are even the most vulnerable people to involve in trading because they don't have any idea, experience and knowledge and they can become so emotional if they lose any amount in trading. Whether you get involved in trading at the early stage of your investment or you choose to wait a bit longer before you start, it does not really change anything because it's same risks even though you have gotten some knowledge while investing at first but it will be foolish to lose your money to trading after you have spent some time Hodling.
