Token will be trading after main token sale.We have offers from different exchanges. By terms of NDA we can't publish names before listing. Exchanges differ in popularity and cost. The more popular - the more expensive. To choose exchange up to our audience size and not to pay a lot, we should know amount of eth we collected. So the decision will be made only after main token sale ends. So we will announce exchange after token sale end. And list ASAP. That means we spend investors money for the result not just for hype.
