Actually trading is very risky. Not everyone can profit from trading. Those who are professional traders can profit from trading. Now those who do not have enough knowledge about trading, should stay away from trading. Now those who want to make quick profit by trading, they will lose a lot of money. I personally don't like trading. I find trading very difficult, I have traded a few times but made losses instead of profits, so I stay away from risky sectors.
You decide to walk away from trading because you feel you are not good enough in trading, that's fine. But those who have a serious interest in trading, they will definitely learn the shortcomings in the trading they do. Even experienced traders can't always make a profit, but what I see is they have the ability to minimize the risk of greater losses.
Trading is not easy, especially for those who are really new to starting. Some see it as very easy to make a profit in a short time, but after trying a few times they will feel how not simple trading is.
