He made a proposal or pre-poposal on dash and the sign very positive but something wasn't quite ok and there was a request for a slightly changed proposal which didn't seem to be a big thing and he was ready to do that.

The next thing was his announcement that he made a deal with NEM and cancled/retracted the dash proposal.

I don't know much about that man but the way he acts let me wonder a bit what "game" he is up to.
He is a politician and a professional poker player which requires both a ceratin character and an undeniable special skill.

So I really do not know what to think about him and his intentions.

Let me tell you that I own some dash as well as NEMs and so I don't care which one he will support but I am very skeptical about him as a person and his intentions in general. I hope I am wrong and he is going to do a great thing for crypto/nem and not just for himself and his own agenda.
