The deducted score of 15 points will return after rolling for 15 days. It does not mean that once you receive the airdrop, it will never come back. The premise is that you must keep grinding to maintain the score.

$MERL No, I just calculated. If one account earns 17 points per day, over 15 days that's a total of 255 points. After claiming 4 times, there are 195 points left. After claiming 5 times, there are 180 points left. If I continue to earn 17 points per day, will I never be able to claim again?
