If you can risk to lose your invested money then maybe yes.
I don't think that Valve, the company which is the publisher of CS:GO and Dota 2, would just allow them to use their games for betting and trading out of their own platform. In the past they have taken down a few sites and companies through law suits because of this. So it will be only a matter of time until they take notice about skincoin.
Hoping Valve will let skincoin to use those games on betting and trading system of skincoin was the fundamental idea of the investors. I also don't think that this will happen. Like any other project, skincoin is also like a gambling. If you win, you'll earn a lot from it.
