Most new contract players don't know the difference between "U contract and currency standard". Let me give you a small example to share.
The forces of long and short in the market are like two groups of people playing tug-of-war. U contract players are like two groups of people betting on which side will win and which side will lose. The coin-based players are like the athletes in the tug-of-war game. So since we are optimistic about which side, why don't we go up and help? Although our power is minimal, we must also use our own strength to help whichever side we are optimistic about. So I still recommend that everyone play coin-based contracts. You can also use football betting as an example.
Starting from 2020, the USDT exchange contract was launched, and then gradually occupied a dominant position in the entire contract market, and its share continued to increase, so the market demand for USDT was also increasing, which is also one of the reasons for the frequent and large-scale issuance of USDT.
