The utility is the 1% daily payout up to 365% of deposits in the Faucet. Drip has a supply of 1 million tokens. If people recognize the utility of Drip multiplying in the Faucet, they assign a value to it. The value goes up and down depending on what people perceive the value of earning 1% in Drip per day. Keep in mind that all markets- real estate, gold, stocks require money to be pumping into them to go up.
Drip has built a network of investors united by a common goal-building the ecosystem larger. The technology is unique because it reinforces (through taxes and rewards) positive actions for the network.
Clearly, people are seeing the value and utility in Drip. Hence, it's the #13 Dapp in the world and has 100,000 players. It's not the right investment for everyone, and clearly you fall in this category. But if you are in crypto and solely are investing for utility, one could safely argue this project has exponentially more utility than thousands of tokens out there.
Thank you for your comment and perspective.
