I have no idea how technically difficult this would be, but it would bring me great joy if
@Dynadot
could implement it so, for their supported currencies, one could choose the one for marketplace listing.
If I was selling example(.)ca and wanted to list at $8888 Canadian dollars, someone coming from Canada and shown Canadian dollar pricing would see that. Right now, I think, it needs to listed in USD so will appear in some complex conversion price down to pennies that varies with conversion rates.
Dynadot has a significant Canadian presence, and is an official .ca registrar. CDN dollar is a supported currency. It would be nice to be able to sell domains to Canadians without it so obviously a converted USD system.
I think there is an opportunity for some registrar with a marketplace to do this right, and they would have an advantage.
