Many theories are not useless; it's just that you haven't mastered their application.
For example, the theory of "comparative advantage," which is closely related to trade wars.
If you want to gain a competitive edge in the crypto world, one of the key points is collaboration. But the question is, why would others choose to collaborate with you?
The answer is—comparative advantage.
You can be the best at technical analysis in the circle, or a scripting expert, or the person most knowledgeable about on-chain data, or even just the one who diligently monitors the chain and helps others solve problems; anyone can find their footing in this.
Don't complain that theories are meaningless; comparative advantage can be applied not only in the crypto world but also provide guidance in broader life.
Unity of knowledge and action; merely knowing the theory is not very useful; the key lies in practice.
