I saw a particularly good example online: Go only has black and white pieces, and trading only has long and short positions. The way to play chess and bet is simple and easy to understand at the beginning. But it is difficult to get started. Now there is a person who wants to play a game of chess with you. If you lose, you give him 10,000 yuan, and if you win, he gives you 10,000 yuan. Will you choose to go directly to the chess table? You won't. You will first look at the chess records and watch others play chess, and slowly find the way. You will go to the chess club and start with 100 yuan per game. After accumulating enough self-confidence, you dare to face the challenge of this 10,000 yuan, but when it comes to trading. How can you dare to bet easily when you don’t know anything❓❓
