Actually WINk, CITYUPTAKE and Pi are build on TRON blockchain, the first is a gambling dApp's reward token (which confirms the impression everybody has about TRON) the other two are dividend generating tokens through a kind of an investment fund with a professional trader giving good returns. I guess everybody knows ADA and they started staking on their Shelley testnet. COTI is a hidden gem with only 7M marketcap but with great potential in my view. Worth checking out.
