It is possible for a long forgotten project to do well after a long time. This has once happened to me with an airdropped I received from coinmarketcap some year back. This coin was dumped but I decide to leave it. It was so surprise to check my wallet and see this project has done well. This is why you should not abandon your wallet with some coin no matter what. There are some people who received BTC in those day but we're unable to access their wallet where it was stored till date.
What project was this?
The project is GHX.
On the good side, you'll never know what a project will bring us because if there's some tokens or coins that have a working developers. They can make things unexpectedly good just as what happened to you.
It is difficult to predict which project will later do well just as you have said. I knew this happened because I'm still holding the coin. No one will like to buy a dead project. If you think it will later do well but layer turn you down.
And I congratulate you with that because not everyone who gets into airdrop ends up with that good result just as you've said and what happened to you.
Thanks.
