Beware! Contract trading in the cryptocurrency world can leave you bankrupt. 9 out of 10 people in contract trading end up miserable. Be cautious, those who guide you to profit from contract trading on exchanges are all scammers without exception. The 'big brother' who leads you in trading spends all day showing concern for you, sharing profit charts, and providing motivational boosts. Occasionally, you might see him driving a Maybach today and a Land Rover tomorrow on social media. The big brother's life is colorful and diverse, so you also want to become like him. Those active on platforms like Douyin and QQ groups will patiently tell you how they made money on exchanges, igniting your passion! What you are copying is not the big brother's invitation code; you are copying his brilliant life. If the big brother can make money, why does he need to bring you along? Don't be moved by his words all day. If he has guaranteed wins, why doesn’t he keep the profits to himself instead of bringing you along? Is it because you look like Wu Yanzu? In fact, it's because you have money in your pocket, so you understand. Many who lead trades initially start with reputable exchanges, but later, tempted by profits, they can't help but engage in shady trading practices with loss-making exchanges, ultimately getting caught by the authorities. Brothers, please trust me.
