There is a very practical problem. As long as you don't enter, you will always stay outside the door. Only when you buy (no matter how much you buy, no matter which popular one you buy), you have to buy first before researching. Don't think about waiting for someone to recommend you before getting on the bus. This is a very lazy behavior. If you can't break this barrier, it will be difficult to form your own investment system to make money. It's not that we recommend you to go in full now, especially not during FOMO. When you hesitate, you should first place some positions. Some people are afraid of losing money as soon as they buy, how can there be no investment without losing money? Don't you need to pay tuition fees to the market? This is one of the cost steps, I don't want to spend money or time, can I wait for good results? Besides, I also mentioned several sectors in March, such as optical modules and storage, which have corresponding stocks in both the US and A-share markets. If you always fear death and don't go into the water, you will never learn how to swim. Is it okay to step on the side and practice?
