Nobody got scammed. It's pretty much like an IPO. The project distributed tokens, not dollars. Coinbase and a few other exchanges listed them and trading started with the tokens fetching a certain price. I sold some on Coinbase, got money - that's it. The token is a "governance token" and I, personally, don't see much value in it but I do not follow this too closely. In theory the token gives the holder a future say in the direction of the projects and maybe a cut of the profits.
