Originally, there were more and better solutions regarding alpha
1. For example, different scores can receive different airdrops.
80U for 220 points, 40U for 150 points.
2. The last digit system is actually good; for each period, those with numbers like 1/3/5 can also receive airdrops.
3. Increase alpha token weight (holding 1000U could earn an extra point daily, for example)
As a result, I don't know which fool thought of the deduction system.
