In these cases the only thing you can do is wait, I know it's boring, but it's the only thing...
You are right, we can't do anything if the team can do anything for us or not. But we can wait to see what team are going to do. Let's wait and see.
But the question is with $50 million why they are not interested in looking for premium exchanges
I think it's not a bad idea to allocate a few percent of funds for a new exchange
If they could really get 50 million dollars then they can list almost all the best exchangers but I do not think they will do that if they did something like that they could not stop responding to the investors or bounty hunters. Anyway, still, I think they will take an appropriate step to make the project successful and will list on the reputed exchange.
