Recently, I've been seeing users getting squeezed in trading competitions in the square. Trading competitions are designed to harvest, making money from your transaction fees, and squeezing your principal. Where do the minimum trading amount data come from? Daily increases of 50,000 or 80,000, with rewards of only around 50 USDT, or even less. Just a few squeezes exceed the rewards, not to mention the transaction fees. Is it really profitable? Or do people just want to have fun, aim for winning, and not care about the costs?
