I don't think there is any such reward to token holders and all the rest of the portfolio tokens are again used to buyback starta and in turn, increases the value of STA tokens.Just clear me up if I made a wrong statement over here.
Sorry, I should write "profit" instead of "reward". My point was that Cindicator was in the portfolio of Starta Accelerator before they create ICO tokens. It seems to me that the profit from Cindicator project would only have Starta Accelerator and they don't have to buy back tokens. But to be honest i'm not sure what they want to do..
