this would not be a good move on his part, for someone who one day was a guy who promoted bitcoin and today want create an exchange that used bitcoin cash as the base currency it clearly sounds like he's hate bitcoin. with this move he wants bitcoin cash to gain attention and other exchange begin to implement bitcoin cash as the base currency. It is sad that he is still spiteful and very sad that there is bitcoin cash and so many other bitcoin hard fork that has strange objects and that only serve to enrich their creators
We all know what Ver thinks of Bitcoin and most of us made it clear what we think of him and Bitcoin Cash.
He would be under no obligation to use Bitcoin as the base currency or Bitcoin in any capacity, it would be his exchange if he chose to launch one. The question about it being commercially viable is more apt because of the saturated crypto currency market..
