Can I sell my course in any desired currency?
Didacte uses the Stripe payment processor as its payment gateway. Stripe allows payments in multiple currencies. You can, therefore, select one of these currencies to be set as the default currency for your platform. You can only set 1 currency on your platform.
If you have international customers, the conversion into their currency will be done directly with their credit card provider at the rates in effect at the time of the transaction.
