I will never forget the day Aptos Airdrop their community. I think I will say Aptos was my first ever testnet to reward me with $1000 dollar worth Airdrop. Not every project will be like Aptos. But Aptos memories will be for long. Airdrop has a lot of advantages too. Not just for farming but to the development side too. Mich awareness is created using Airdrop compaign everyone will know the project exist which is no more cost to the project. The valuation and market cap everything will be influenced through the Airdrop campaign. Because everyone will want to partake. Look at Arbitrum Aptos Sui despite disappointed their community even zksync is already goes up.
