If I may ask.
If for example, there is a person who has USDT and want to trade with you. Let's say that person will receive 100 USTC from you right? In return, how much USDT will you receive? 100 USDT too?
You said that 100 USTC = 100 USDT and 1 USDT = 1$. So you're saying that 1 USTC = 1$ until now? You aren't a fan of Do Kwon right?

. That's unfair trade. Just move on and claim your mistake.

That would be better for you and for the community. Lesser stress
Why do you think I should exchange 100 USTC for 4 USDT if I bought them for 100 USDT? If you bought BTC for 60,000 USDT, but it isn't currently valued at 60,000 USDT, and you created a topic in the exchange thread: "I want to exchange 1 BTC for USDT", but described the exchange conditions in the topic: "I want to exchange 1 BTC for USDT.
1 BTC = 60000 USDT, so you get 1 BTC.", would this be considered scam?
