I wonder, who is so ignorant and dumb to waste their money on something as stupid as a token which gives out "free" tokens for empty addresses as an airdrop? Oh yeah, those who benefit from such ponzi scams. Something similar happened to Bitcoin, where they got "free airdrop" in a matter of hours, like BCH etc.
Well, UNI airdrop wasn't given to empty addresses, it was only for those wallets which interacted with uniswap with at least one trade of $20 worth. It's free money for those who interacted with it, what's wrong about it? People are free to buy or not to. Uniswap is dex, what's ponzi about it?
