TRIA is on Etherdelta
COMBI will be on exchange end of this month as far as the team has communicated. Exchange on which COMBI will be listed is currently unknown, as the team cannot disclose this due to NDA. There is a possibility to trade COMBI now on Etherdelta as well by using the COMBI contract address, but volume is low and the price is at a discount compared to NAV.

If you were in the ICO you should have both COMBI and TRIA, check you wallet!

And yes Appie, the team already communicated multiple times that the value of COMBI when it hits exchange will not be driven by demand and supply, but purely by the value of the underlying assets (which then again are determined by demand and supply ofcourse). The total value of your investment since ICO is then indeed TRIA + COMBI value.
