Charging a registration fee for airdrop distribution doesn't legitimize a project—it's often a red flag. The PocketiFi incident should serve as a cautionary tale here. Plenty of users forked over registration fees only to find their airdrops vanished entirely. When a project needs upfront payments just to claim rewards, ask yourself: whose interests does this really serve? Self-funding claims sound good on paper, but they don't guarantee transparency or actual delivery. Before committing funds to any airdrop program, do your homework. Look at the team's track record, check community feedback, and verify whether similar projects have followed through. The crypto space moves fast, but that's exactly why due diligence matters more than ever.
