I think I know what you are trying to do here. As you have said, you are looking for coins that used the uniswap to exchange the coins or token to be eligible for the promotion of uniswap running now. I am also one of the people who earn money from uniswap around $1900+ to $2000 because I am an old user of uniswap. You also expose yourself being vulnerable to scammers.
Do you mean uniswap airdrop?
As I know uniswap listing process is unpredictable. Few time I saw 'token XX listed' and no more. So I'm trying to take some info from sources I have posted above.
