kind of scam but many people tried and got success.
You can't call a service scam so Lang they always pay. as long as they pay you can not complain.
Not really. If they don't actually invest in mining then there is no actual profit being generated. They could be just paying from other users funds. The problem with that model is that it will collapse eventually.
In this way I think so too.
I think the owner invest in mining. This site has a low ROI because you must login everyday and collect the ore. Not every user could have time to collect the ore everyday and thereby another user get more ore or that's why the rewards are high.
This doesn't mean this isn't a risk investment because if every user who invested in this site collect everyday ore then this game drain out of funds and the owner can't pay more than he mines.
I'm not sure but this can be the system of Ore-Mine
