When the fundamentals of a certain currency change, all you have to do is to join the optional observation as soon as possible. Let's take another example of Etc. Luna has no fundamentals. In layman's terms, the current Doge is similar to Etc after Eth20. One is that the fundamentals are getting stronger, and the other is getting weaker. In this way, you can quickly find the variety you want to buy when the market changes, whether it is long or short. The more familiar you are with it, the more confident you will be, and the more stable your position will be.

I'm very curious when the fundamentals of a certain currency change, why do you want to compete with the market and the consensus direction in order to get a small profit?

Go long on the strong and short on the weak. Sadly, most people are doing the opposite. Essentially, they still want to make quick money, just the little money that can be earned during a correction or rebound. If you can't stand long-term positions and fluctuations, you really deserve to lose money.
