What this means
An airdrop usually distributes tokens based on eligibility or participation, while a presale sells tokens before a public launch.
Core ideas
What to understand first
- Airdrops may be free or require only gas to claim.
- Presales usually require payment before token delivery.
- Airdrops often reward behavior or status.
- Presales involve purchase terms, pricing, vesting, and project risk.
Safety checklist
What to check before acting
- Check whether money is required.
- Check whether the page asks for approvals or signatures.
- Read token unlock and vesting rules.
- Verify the official links before interacting.
Risk note
Common mistakes to avoid
- Fake airdrops and fake presales both use urgency.
- Presales can expose users to payment and delivery risk.
- Airdrops can expose users to wallet-drainer risk.
