For example, blockchain projects such as Hero Chain and Space Chain were recently filed by the public security department for alleged fraud. For example, OKEX has 460,000 bitcoin bulls exposed. For example, Sun cashed in 654.38+02 billion Bo coins and fled to the United States ... If the exchange strictly examines these scams when putting them into circulation, they can be avoided. Therefore, investment is still a platform to get rid of fire coins, which can be more reliable.
