Let's break it down into a few points.
The first point is the basic knowledge of exchanges. Know how to register, how to verify, how to transfer, how to buy coins, how to sell coins, what spot trading is, what contracts are, and where to find basic information. This will probably take a day or two to explore slowly. There is no technical aspect to it, just get familiar with it.
The second point is to understand the basic underlying logic. What causes the price of coins to rise and fall? Which exchanges can be used, and which cannot? Which coins can be bought, and which cannot? What is the reason for the existence of whales?
The third point is to build your own trading system.
The fourth point is to manage your positions well.
The fifth point is to implement good risk control.
The sixth point is to control and manage your trading mindset.
That's all for the basic knowledge; the rest is gradually understood and perceived through practical operation.
