If someone posts a purchase order to lure you into saying that it is easy to make money in the cryptocurrency industry, you must see how he makes money. If he makes money by long-term holding or fixed investment, then he makes money by industry growth and cyclical trends. You can copy his method. If this person says how much money he makes by contract trading, then he must be a liar and fake. Regardless of whether it is true or false, please treat it as a fake. It will only benefit you and not harm you!
