You guys are really amazing, I've been grinding for over 20 days and haven't received a single point. At first, I thought that grinding 11 points would be enough, and sticking to the principle of not wasting, I earn 11 points every day. The only time I didn't exchange points for an airdrop, I ended up missing it by 2 points, it's really frustrating! At this rate, I estimate that my 15-point tier is going to be for nothing again.
