He will probably use Bcash with all pairs but not the same with BTC xD
if he tried to replace BTC pairs with BCH, the exchange would fail miserably. traders would avoid it like the plague. altcoin traders are trying to profit in bitcoins, not bcash.

You raise some interesting points but if memory serves me correct Ver was an investor in ShapeShift, now look at the state of it.
With his reputation and track record I doubt he would contribute anything positive as all he does seems to have undercurrents of his desire to either control Bitcoin, to take over it or destroy it.
i don't think the situation with shapeshift (or its direction) has anything to do with roger. i bet shapeshift was getting a lot of heat from regulators (probably in the USA) for not implementing KYC.
side note on that---now coinbase is even requiring KYC just to send/receive crypto. something larger is amiss here.
