PoWH3D is a zero sum gambling game, the only use case of the P3D token is to play the game. The game is an investment simulation that seems to draw it's inspiration equally from pyramid schemes and cryptocurrency shitcoins. It's the greater fool game with no guarantees. The fact that it's entirely decentralized and open source, that there are no devs trying to scam anyone, that it's all run by the smart contract, is fairly brilliant. The game is running itself. The devs couldn't shut it down if they wanted, it can just keep being played indefinitely. Not such a bad thing for people who enjoy gambling.
