Before trading a beginner needs to have a basic understanding that trading and earning profit is not an easy thing. In your statement you clearly mean that people fail in trading due to lack of knowledge yes it is correct. For trading you need to educate yourself in previous trading education and gain enough experience about trading then start trading. If one does not know about trading and gets greedy and trades in the hope of making profit, then he can sometimes end up in loss. You will find that there are many new traders who trade by watching others or guessing but they have no experience in trading. Those who trade on the advice or guesswork of others have never succeeded.
The concept is that we must understand that trading does not always produce profits and it is no exception for people who are experienced. The difference is that people who are experienced know how to restore losses in previous trading so that they can run trading in a simple and easier way to control. Trade does require knowledge so that people can avoid the risk of excessive loss and knowledge will give them a much better picture of trade.
There is no successful trade because it depends on the guess and not the way to get involved in it. Trading will be much more risky if someone does not have knowledge about it. Therefore, before trading people should learn the right way so that they have the right way to be involved in trade.
If beginners want to start trading then they should start with a small amount of money so that even if they lose that money they don't incur huge losses. Market volatility and market analysis need to be correct before trading. Beginners need to have the mindset to deal with greed, emotion and stress when trading.
That is a way to avoid losses for people who do not have knowledge about trading. Starting trading in small amounts of money makes them much better prepared to face the risk of loss and they can learn to develop trading skills if seen directly. A beginner must have the ability to avoid greed and emotions because it is very important to pay attention.
