A kind of scheme that everyone should avoid. A promised of growth without taking any risk is going to end up falling into the pit of devastation and frustration.
The commission thing which I understand doesn't really apply to make people believe that they will earn from it. That's the exchange's job to take commission and not the investors.
they will not earn from it. they just share risk and profit. This smartcontract make not important price on ether, important only one think, how long you can hold ether in token, if you can do this longer than other OR if price on ETH will grow more %%, you will get profit, If you will hold token not for long or ETH price is down you will incur losses. I mean, if you miss the maximum price, you will receive a part of the profit of those people who did not miss it.
