I do rebates to have a stable income, and at the same time, I can help everyone save on transaction fees, for example, we can save 40% on fees. If we incur a fee of 10,000u, we can get 4,000u, and this 4,000u is what we saved, nearly 30,000R to improve our lives, isn't it nice to buy an iPhone 17 with it? Why waste it for nothing?
