From Airdrop? More than 2.000 USD (Bitcoin Rhodium). From Bounty? Probably around 150-200 USD (Parkgene). I have over 30k followers on FB, so I receive a lot of stakes. It's not a lot if you compare it to airdrop, but it's a great amount of money for just posting on FB for a few days.
It’s hard to remember, but if you count those that I could sell, then it seems about 200-300 dollars on the Rally token. I participated in their bounty on some platform, and after I received tokens that I could immediately sell. I can’t recall higher awards. Moreover, bounty programs were often an ordinary scam.
