The airdrop activity #空投操作全指南 is just for big holders, repeatedly brushing, with deducted fees, and the risk of buying in and then experiencing a sharp drop. Each time the activity comes out, the score requirement gets higher. The platform earns fees, and the project party can cash out the coins they hold by selling to retail investors who are brushing scores! I started brushing scores as soon as the activity came out, and I only have a total of 63 points, which is 2 points short of the airdrop standard of 65 points, meaning I essentially played for nothing and still lost on fees. So I won't buy any junk in the future!
