I don't know that there is a staking program for populous project. where I can find this program details?
This is new, staking rewards will start from next week. Simply put your PPT and PXT Token on the POPULOUS-Exchange, here:
https://exchange.populous.world/de/?register=1&refferal_code=g7qzncPopulous owns now a Etherium mining-factory, ETH will be paid out every day. More facts are known to me, but please wait until Populous will make an official press-release.
In my opinion that if the populous team wants more attention from investors about their stake program to consider make it as DeFi platform.
