Assalamu Alaikum,
I recently came across a project by the name of Titan X it on the Ethereum Chain, the project was fair launched and people virtual mined the Titan X tokens once they mined the tokens then they had the option to stake the mined tokens or sell it on the open market. The staking rewards were collected from fees generated from mining process, also there were bonus rewards for early miner adopters, are all these mechanics with in the protocol halal or haram. here is a link to the white paper TitanX.win Pumpamentals | TitanX.win please
jazakallah khair
