According to feedback from community users, there may be a loophole in the WhalesMarket platform's WLFI over-the-counter transactions: Address A first sells the token to the B address it controls at a unit price of 0.01, and then the B address sells it to the buyer C at a unit price of 0.2. B can get the difference, but A does not deliver the tokens afterwards, and C can only get liquidated damages at a unit price of 0.01.
