Profits depend on painting. The main way for spinach companies to make profits is pumping water. This word is believed to be familiar to lottery players. Pumping corresponds to the return rate. For example, if the rate of return of a game is 95%, then after you bet 100 yuan successfully, the spinach company will turn against you in 95 yuan, and the remaining 5 yuan will be the pumping and net profit of the spinach company. Therefore, regardless of the outcome of a game, spinach companies are making money. Spinach companies don't need to manipulate competition, and they can make a steady profit without losing money.
