Old man, that's right. But from my experience I can say that you can only learn the market through trial and error, and it's only possible with real money. Theory doesn't work without practice.

What I learned on the crypto exchange.
Lesson 9.
If someone tells you that if you enter the crypto market with $ 100, you can become a millionaire. Do not believe it, you will not. You will have more chances if you enter the crypto market with $ 100,000, then you really have a chance to become a millionaire, but you will still have a very big chance to lose everything. So
before investing money, study the market, and then invest.
