Nah, many people are not fit to trade. Don't do it if you just want to make money. It aint gonna work. Don't do it if you need to find a teacher to help you. It aint gonna work. Everything is available online for free and in your public library. I never had to buy a book.
Demo trading is only good for getting a feel for how the platform works. A profitable demo trade is nothing like a profitable live trade. The difference is a demo profit is not a real profit. You are not actually taking money from another trader. When you make a profit in a live trade, you are taking real money from another trader, which is very difficult to do. Lots of beginner traders like to think of trading stocks as these things that just go up and down in price. It looks easy to do on the surface. This is a very common misconception. As a beginner, becareful because it is what you don’t know that will hurt you. Investing is a much better way to make money. Trading for a living is next to impossible.
