According to ChainCatcher, ZKsync founder Alex G said on social media that ZkNation is building a resilient community by using multipliers based on external signals (such as continued holding of previous airdropped tokens). He predicted that holding STRK, ZK, and ZRO will become the most reliable airdrop qualification signal in the future.
He said that airdropping to those who remain in the ecosystem after the airdrop is a wiser design, and those who sell the airdropped tokens instantly will regret it. He also made it clear that this is just his speculation about other projects and does not imply any specific arrangements for ZKsync. All decisions of ZKsync will be made through public governance.
