Ok I have been hanging out on their forum and slack.  No-one really knows why jubi is delisting XAS and NEO.  However the coin is still being actively developed, and crucially this is actually happening in partnership with the government.  The are actually waiting until they get approval e.g. before listing on foreign exchanges.  Although obviously hobnobbing with the government isn't everyone's idea of how to run a cryptocurrency, in China it may be a wise strategy for a company that wants to go large.  Anyway most places to buy and sell are off-line now so you are either in or out... I am in.  Think it might be a longish wait but then positive news.  Fingers crossed!
