Holder airdrops distribute free tokens to those that hold a certain amount of digital currencies in their wallet. The project team usually takes a snapshot of users’ crypto holdings on a specific date and time. If the wallet balance meets the minimum requirement, recipients can claim free tokens according to their holdings at the time of the snapshot.
Many new projects airdrop tokens to bitcoin (BTC), ether (ETH), or BSC wallet holders, as they have the largest communities in the space. For example, Stellar Lumens (XLM) airdropped 3 billion XLM to BTC holders in 2016, and the airdrop was exclusive to users in the Bitcoin network.
