Mainframe did real physical airdrops of their tokens. They traveled all around the world (Hong Kong, Warsaw, Shanghai, Zug, Beijing, Paris, Tokyo, London, Seoul, Amsterdam, New York, Berlin) to meet their community.

For true mainstream adoption of a protocol like that, this is what needed to happen.
