This thing has strong liquidity, some merchants earn money every day, sell when it rises, today the business received payments, after sleeping for a day it rises by 10%, 20%, isn't that just picking up money for free? Occasionally it's fine, but it can't happen all the time. If someone wins, someone has to lose, who will take the 10%, 20% loss? The big players definitely won't allow it. The currency used for payments, today's business received the money, tomorrow they sell the goods and exchange back to U, as long as it doesn't drop, it's a qualified payment currency, and if it rises, it's unexpected wealth, but where is there so much unexpected wealth?
