Now coming some airdrop which are paid or need fees like various Network bridge, staking, holding liquidity etc. This kinds of airdrop beeing successful. You can justify it. Some days ago i also did many airdrop but not get any payment but now a days i received some payment from airdrop.
Most of airdrop right now not free and become paid airdrop, if you don't have capital its difficult to earn airdrop coins with task bridge, buy nft or holding until hold some coins on their network to qualify airdrop participants. I think not easy as usually earn from airdrop last two or three season just filling form and airdrop landed to our wallet, but right now need to bridge, swap and many paid task have to do if want get qualify or receiving airdrop coins.
I stop with retro or paid airdrop and looking any free airdrop although reward usually very small than paid airdrop, warpcast platform have many airdrop and need to be faster behind allocation reward too small participants.
