Since airdrops have gone retroactive, all is speculation which ones will do airdrop and which ones won't.
This is thread to post your airdrop speculations.
I think best airdrops will be ethereum ecosystem airdrops
Eg :
1. Eigen layer
2. Swell network
3. Ether-fi
Also you can try out cosmos airdrops as well. Also keep stake the TIA. There is lot of airdrop will be checking the TIA staking as well
