Does anyone know when coinexchange.io fix the MAC wallet?
MAC is traded only on two exchanges. And one of them is not working with MAC.
How long can it last?!

Sorry, I wish I had an answer... You will have to ask coinexchange.io
Are you still looking to complete the roadmap you initially posted? How about the Segwit stuff, has that been successfully implemented?
Yes, everything on the roadmap is still in play, just different dates. Even Segwit activation. A new map will be released soon.
