They don't exist. They mainly earn money by brushing their bills. No one can achieve the accuracy of 100%. Last year, I earned 10 million dollars by myself. My goal is annual income100000 USD. After one year, the principal has changed from100000 to more than 200000. The accuracy rate is about 95%. My method is to break down the profit target into 250 days, earn enough 30 points every day, and then turn off the computer and sleep. I never consider making more money. I mainly play pound day and gold.
