I never expected that stopping the alpha grind a week ago was the wisest choice. Now at level 3.2, I'm definitely a clown. Based on 15*18=270, if I assume that the average passing score is 223 points for the next round, grinding at level 3.2 for 15 days can only earn 3-4 airdrops. At today's airdrop price of 30u, that's worth 120u for 4 airdrops. Then the 15-day cost is 15*8=90u. Thankfully, there's still a profit of 30u. I'll continue to grind.
