The ALPHA airdrop deduction of 15 points has a design flaw, because there is a 15-day cycle, with one day added and one day deducted. Normally, if daily points are not increased, the total points over 15 days remain unchanged! But suddenly 15 points were deducted, how can these 15 points be restored? Does this mean that an account that has claimed several times is rendered completely useless? Is this what Binance wants, or is it a design flaw?
