The devs promised they will be selling the coins they got from C-CCEX once again.
You must have been mistaken, we've not made such an implication at all. What's done with the HEAT tokens received back from CCEX will be decided later after CCEX actually decides how many tokens they'll send us and when they'll do that. Original amount to be received was something like 300k HEAT.
Those tokens will be used to support company development in the way that best supports the HEAT token price and / or company share value. Possible options include giving them out with company shares to be sold, selling tokens as such, burning them etc. This will be decided by us the company when relevant.
Burning them or sending them to users proportionally to the current balance would benefit the value of the project.
