I see how it is.

This is what being squeezed really looks like. Large transactions are generally detected by squeezers, and there is a risk starting from tens of thousands of dollars. When a large transaction is detected, those well-known squeezers automatically use higher gas fees to jump ahead of you in the transaction, raising the price, and then immediately sell. The usual wear and tear you experience is caused by the lower pool's transaction fees and the price difference of the coins!
