Not masterbrain, but a promoter who I guess mostly uses youtube.  I don't think he's done any of his own coins yet.

I think he's trying to be the turnaround business guy with cryptorush, but the pressure got to be too much.

They got bitten a couple times by bad coins on top of the BTC hack etc.  I don't know what they expected using the OpenEx codebase, which thankfully appears to have been pulled from github.

I get what they were trying to do with CR, but you can't expect to be successful using a codebase that was known to have, umm, "issues", and throwing every coin that comes along up on the exchange.  So many coins being put out now from the generator and inexperienced developers with random defects.  If you're going to do it you gotta have an experienced developer thoroughly checking every coin, and that quickly becomes non-scalable/unprofitable.

I think they learned some lessons.  At least they haven't just closed up and run away, and are actively trying to shore up the site and make everyone whole...which is more than you can say about some other exchanges lately...
