There are three types of people who make money from contracts:

1. They make money with small capital and rely on the winning rate. Strict discipline is required, and you must withdraw the money you make.

2. They make money by the profit and loss ratio. If the winning rate is less than 50%, but you make more than you lose, you make a lot of money.

3. They rely on rolling positions, such as Tony who made 50,000 dollars to 10 million, 400 times the Dogecoin for lunch, and the female college student who made 10 million by shorting Luna, and Liang Xi's 1,000 yuan to 10 million, all made money by rolling positions. #BTC
