Do we have to pay with our own currency?

We are building our own marketplace where our games going to be sold. But we are not selling them for dollars, we are going to make our own crypto currency. Do we have to pay you with our currency in that case?
,

Unfortunately, we can only accept payment in US dollars.

Can you provide us with more information on how your process will work? Will there be a step by which you will be accepting US dollars, or another form of government back currency, in exchange for your crypto currency?

It might be, but much later.
