By the way, let me share a little useless trick for grinding points. Many people grind 15+2 to get four airdrops, or even more often, 16+2 to get five. This is actually quite wasteful.

If you grind 15+2, you can get four airdrops per cycle, but at the end you'll have 17*15 - 15*4 = 195 points left, just 5 points short of getting another one.

If you grind 16+2, you can get five airdrops per cycle, 18*15 - 15*5 = 195, also just 5 points short of getting six airdrops.

So here comes the question, to claim 5 airdrops, you only need to have your last score at 200, so 260 points is enough. That means you need to brush 15+2 for 10 days and 16+2 for 5 days to get 260 points. After claiming 4 airdrops, you still have 200 points left. In fact, you only need to spend about 2*5=10U more to claim one more airdrop. In one cycle, you will spend about 20U less than brushing 16+2 to claim 5 airdrops. In a month, that is 40U$ETH #空投入门
