I was one of the lucky one to receive large amount of UNI token when they initiated their airdrop a few years ago. However, I sold all my token when I received them since the token is only used for governance (voting) and not related to financial return of the uniswap platform itself. I would have been much more excited to keep my UNI tokens if transaction fees generated on the platform would have been used to distribute some dividends to token holders, unfortunately it was not. The token price still grew a lot more than I expected maybe in the event that an entity or group of entity decided to take over the management of the platform through a hostile take over on the token. However, at this point this is a bit unlikely.
** update ** Uniswap is planning to start giving out a rev share to feed back into the token economy, so the governance token is now directly related to the financial performance of the exchange. This is a massive step, and I upgraded my ranking accordingly. Show Less
