Every day earn 15 points, after 15 days, 225 points, plus the 15 points consumed for receiving the airdrop and deducting the 15 points you earned on the first day, which counts as the first day's 15 points. That means a total of 30 points need to be deducted, leaving 195 points. If you make up for the 15 points the next day, you'll have 210 points remaining. If you keep earning 15 points daily without claiming the airdrop, your points can maintain at 210, unless you earn more points each day. Following this pattern, claiming an airdrop deducts 15 points, and after 15 days, an additional 15 points are covered, totaling 30 points. This way, claiming an airdrop would mean deducting 15 points from 210, which equals 195. So, are these points one-time only? Because claiming the airdrop deducts 15 points, and the points deducted after covering 15 days consumes a total of 30 points at once. Doesn't that mean each account can only claim a one-time airdrop?
