The crypto to fiat instant conversion and transfer will be huge, its one of the most important feature for crypto trader and there is relaly a lot of people in need of that. If ternion sucessfully deploy the fiat gateway, the exchange will be really huge I think.
We will see how much the crypto -> Fiat gateway is worth. It is a nice feature, but will it be enough to pull people to their exchange?
It depends on the exact conditions I think, KYC, wd-limit and I cant imagine that every country will take part in it.
