We keep on waiting for good news about this project. especially if this exchange problem is solved.
It took a long time but I think it will be profitable for everyone

I think so. As far as I am aware the exchange is ready. I can understand how people might be anxious and a bit upset since they're expecting it these days.
It's an odd position for them, but I think the result will be good.
I can also tell you that the devs are aware of the feedback and they're taking it all in.
