I am wondering myself of there are truly dice projects that are truly decentralized. The closes I can think of is Tronbet and TronVegas both of which have their own utility token, Ante and Vcoin respectively. They are both Tron-based tokens and they are used  to distribute a portion of the platform's earnings. I am not sure the exact percentage  but it is pretty profitable. Dividends are distributed daily, instantly and automatically in to the Tron-wallet. They say in gambling the house always wins since we can be the house then we always win on this one. Tronbet's Ante tokens are already tradeable  while TronVegas' Vcoins are not (Except in risky TG P2P trading channels) but can be mined in their site by playing their games.
