If it's an Airdrop, of course it doesn't guarantee that it really pays, but if you pay then you're safe. There have been many rumors about the Metamask airdrop and these rumors have only been speculations for a long time. However, it doesn't hurt to try if you have enough balance to interact with the new Metamask feature. I think it's simple, if you are really interested, try several transactions using the BSC or Polygon network because the fees are affordable. After all, you're only charged swap fees and bridge fees. If the rumors turn out to be true then you could have a chance. We can't all guarantee 100%, but when it comes to the potential for Metamask to launch its own token it's definitely good news for users who have interacted.
