As an investor, you should learn to be responsible for your own funds. After all, your money is earned through hard work, not just lying on the back of water. Therefore, before investing, you must learn the ability to make judgments. There are many salespeople nowadays, and they will not treat your money as their own. For one reason, teachers cannot only revolve around you, unless you are a millionaire. So when you set an order, don't panic and start looking for your teacher. Instead, be calm and follow your own judgment to make the most correct choice. Then go to your teacher and see if their opinions are the same as yours. If the direction is clearly reversed, be decisive and take advantage of the situation.
