For some time now, Metamask has been making references to an MM token. Given its current valuation of $7 billion, this may be the largest airdrop ever.
I haven't found the reality of the source, maybe you can add it here.
Well, anyways, Metamask is making its way to always have interest from the community. They'll need to keep stay on track which is why they are doing some airdrops but with the huge number of its users, the allocation is small enough to compensate the participants, and sometimes it was just ignored as it doesn't matter by many users because what they need is the good service coming from this platform.
But if this is true, I hope they are true to their promises as well, otherwise, this will be the reason for distrust.
