Yes I do received coins or tokens from my past engagements in bounties and airdrops which I have already forgotten that I get to engage with and to think that I can already never be getting any from those engagements but luckily it was a surprise to see that after a couple of months not checking my account, for I just randomly join into any available bounties and airdrop which is for me is just a trial and error, I was shocked to see that I got mysterious coins in my wallet to think that I cannot already remember when and how did I get those. It was just good that even you did not expect or having a hard time to remember your engagement into such projects, still you have been able to receive coins which is a proof that even it takes time, such projects have been able to provide and manage to give you the rewards you deserve. It is just that you do not know if those do have value or not. It was just surprising to see unfamiliar tokens in your wallet that came from those bounties and airdrops you have already forgotten to got engaged with.
