This article states that holders of the TIA token will also get airdrop. If you already have TIA on your wallet, you don't need to do anything - you'll get the Airdrop. If you were planning to buy TIA tokens, however, DeFund's Airdrop is another reason to do this (not a financial advice!).
Participating in airdrops is your choice and your risk. We don't guarantee any rewards. Connect your wallet only to official websites. If someone asks you to send crypto – it's a scam.
