Is there any payment gateway the Edwiser Bridge accepts?
You can use different payment gateways other than PayPal which is already integrated into Edwiser Bridge. You can download Woocommerce which will offer you an option to integrate different payment gateways and set the currencies which you want. Woocommerce can be used along with Edwiser Bridge and you can sell your Moodle courses as Woocommerce products.
