This was what surprised me too, I hard all the opportunity to have associated any of my wallet with Uniswap but due their fee during swap that scare me away if not I would have qualified for the massive dropped.
Well if only we knew that even a small amount of trading on uniswap will give us free uni airdrop we already do that. But no one knows that uni will give airdrop to its users. Lucky to those who made thousands because of uni airdrop.
