Why do 90% of people lose in a game with a 50% probability of profit and loss?

Because the opportunity is only for a moment, the profit is only for a moment, and most of the rest of the time is not suitable for placing an order, and it is impossible to place an order and lose money. The probability of loss must be greater than the probability of profit. This is the market. Just like a hundred arithmetic questions, there are many wrong questions, but there is only one answer, so there are many mistakes and few right ones. This is the law of nature.

Laozi said the way of heaven. The bigger the capital, the harder it is to lose, and most people have small capital.
