Quick question regarding the airdrop. If you haven't traded on uniswap before is it too late to receive the airdrop? Is there a link where I can find more information (I checked already)?
yes you are no longer able to receive the free tokens from airstrip if you are not using that platform before they give that free coins.
There are many persons I know that receive free UNI tokens and its worth it of waiting .
But there are other options such as you need to make liquidity in that exchange and you will rewarded in tokens in the future.
