It's odd that yobit won't add this - it would bring a ton of volume for them.
From my understanding, it was never presented to them. Maybe I'm wrong. What are the steps to get this accepted into YoBit? I've got a few thousand Mrai waiting to be sold, and I don't trust the two exchanges that are currently trading XRB. Not that I trust YoBit any more, but they'd be a more welcomed addition.
