Though you can't earn with ROKS tokens if you aren't an evangelist, you will be able to earn with EVAN tokens that will be free but only at the start.
EVAN tokens? Can you tell more about them? And how it will be possible to take them for free at the start?
EVAN tokens are essentially territorial license. You get it for free when you install the MainSale app (Android or iOS). See Step 6 in this video where it shows at the top: "FREE! Get Territory License Now (Limited time only)":
