if we work totally in airdrop project , many times ita give alot reward than bounty campaign. There alot potential airdrop that may we meet and give thousands dollar.
airdrops also have so many shitcoins, it's 99 out of 100 that you gonna encounter shitcoin airdrops and get useless reward, I think it kinda depends on how you could choose the project.
after all it's always the shit projects that populate airdrops most of the time, currently the high quality airdrops always require some kind of staking like in binance where you are required to stake some amount to get airdrop of a project.
shitcoin not found only on airdrop prgram, event project that launched on good launchpad like binance could be too. Take a look on mexc pad, alot shitcoin created there although as we know mexc was one of good exchange with high trading volume.
