In simple terms
Airdrop farming means using a protocol, completing activities, or maintaining an on-chain presence in the hope that a future airdrop will reward that activity. If no distribution has been announced, the farmer is pursuing a possibility, not an entitlement.
How it actually works
The project decides the criteria, snapshots, allocations, and excluded addresses. It may consider genuine use, duration, variety of actions, or community contributions; it may also filter bots and clusters of wallets believed to share one controller. Repeated transactions or visible points do not necessarily reveal the final rule.
The cost to measure
The economic result is the value actually received minus gas, fees, locked capital, failed operations, and time spent. Before any claim, there are also smart-contract, bridge, token-approval, and phishing risks. An unexpected token in a wallet is not proof of an authentic reward.
What it does not prove
Activity, volume, points, or many wallets do not guarantee eligibility, allocation, or profit. Anti-Sybil filters may exclude artificial behavior, and eligibility criteria may remain discretionary. No guide can predict an unpublished distribution.
