I didn't join a lot of it but I think BCH is the airdrop that the last one I've received. That's why I've missed a lot of them but I am not regretting that I've never joined a single of them since the last one that I've got for free. I'm just happy to see those people that have been sharing their wins with airdrops especially the last ones for this year which there have been tons of it in social platforms and even on the forum.
He is talkin about retro airdrops here and the one that you get on BCH seems different. BCH is a fork of BTC and as long as you have a BTC, you can get an equivalent amount of BCH (AFAIK). That happened long time ago. Unfortunately, I only a get a few of it because I only have a small amount of BTC that time.
Yes, you shouldn't regret of the airdrops because many of them are just a scam. I'm sure what you are doing by the time they are coming out are more worth it. NFT and P2E games on the other hand are popular last time but again, many of them are just a flop. But if only you don't hold them longer maybe you can also earn something out your capital.
