I'm not advocating or promoting u guys to invest a small portion of what u are hodling in smart contracts.
I know most sounds like a Ponzi scheme and u need to really know like anything the risk involve.
But that's what I'm doing while my rig is hibernating. At least I'm still earning eth.
What are you referring to exactly? Are you talking about masternodes?
I didn't think you could earn anything in smart contracts, it actually does sound like some type of scam however since its a smart contract you can always just look at the source code and see where your money will go.
Maybe give more info about this passive income method you are using?
