I think max 100% increase, so 2 USD. And even that is not two times higher, as most of the investors in reality paid more, i.e. some 1.25 USD, because of the transformed rate. It also depends on the timing of course. If we predict current (not so bright and volumeless market) it may be quite low if the NEX going live is too far away and with it, the community disbelieves the team. You have to know that crypto community is extremely irrationalt and quite inpatient, thus with time you lose their confidence, no matter what.
