The core logic of transaction mining is actually quite simple: transaction fees are not just transaction costs, but also a source of revenue.

Let's talk about the first advantage - negative cost trading. After each transaction is completed, the originally paid transaction fee will be refunded to the account in the form of rewards, thereby offsetting the costs. While users engage in spread trading, they can also earn a certain amount of transaction fee rebate income, which is equivalent to having an additional stable source of income. This mechanism allows trading to no longer solely rely on market judgment, but instead offers more certainty in returns.
