As far as I'm concerned, announcements of announcements should be avoided, they seem to just create hype, pumps and dumps and burnt people. And no matter when the announcement is made, insiders will always dump on late comers, that's how it has always worked when a new listing happens/is announced.
As for a listing on Binance, I think the probability is very slim, because they don't have a history of having the coin devs hint to a listing on their platform, but who knows. Anyway, imo it's not gonna be Binance, I just hope it's not HitBTC...
