Some people lose money and others make money in this market. What's more, some people just come to this market to preserve value and may not make money, so they provide liquidity and may also lose money. Where did all this money go? Can't be completely consumed by the handling fee of the exchange. So few people will speculate in futures to make money.
However, this is really too difficult. Without enough time, enough capital and good willpower, this road is difficult to get through. The key is to find the right method, and it is a method that suits you, which is very difficult.
