Being on an exchange is always a positive imo.
It does not mean you have to like or use the exchange.

Bitcoin and Ethereum for example are on that exchange.  Are they degraded somehow by being on there?  No. Of course not.

XBR's issue is that it needs to grow its community and market itself better to get more demand.  It also need to get on more exchanges.  It could also bring back some of its powerful uses like to be used as a reserve of token projects.  It could use dev work to enhance its wallet features to connect it better with other cryptocurrencys.  These are the issues that factor into XBR right now.  Not this one exchange.
