Everyone should develop corresponding strategies based on their own personality (investment style).
For example, I have a friend of a friend. In the last round, he studded the early#lunaand earned 20 million. In this round, he studded the early#injand#seifor 20 million. He made ten times the 200 million and quit the circle.
Of course, this case is quite extreme, and the probability of most people turning over in just one currency is extremely low.
I can't do it, so I adopt the "family bucket strategy". I buy 1-3 types of leading products in each sector and spread the funds as much as possible. In this way, when rotating, I also have the rising sectors, which makes me feel much more comfortable. , you can also have the patience to wait for sectors that have not risen, so as not to change stocks and sell out.
There is no such thing as better, what suits you is the best.
