I came across it in 2019 on Toutiao, and then I casually found an invitation code online to start mining. I've been mining intermittently for over 1300 days and have promoted it to more than 10 people, but now only 4 have completed KYC. My coin amount is base coin 2988 + (layer coin 9968/11 = 906.18 * 4 people who passed KYC = 3624.72) = 6612 PI coins. Let's go, PI friends, believe that the efforts will not be in vain!
