I believe that beginner's should understand how the system in the market work's like buy when the market price is low and sell it again when it increases, with this simple rules, anyone can be very rich if they are patient enough on the different situations in the market.
Not understanding the system, the past, the movements and all that brings about the value in the industry is what has made a lot of beginners to invest blindly till date and still making grievous mistakes.
As long as they can understand there is a future for the market and there is likelihood of speculation driven market, they will know how to apply their senses into making the best of the market but these days, we just have some set of people who are looking for ways to just get rich overnight without doing anything for it.
