One of the App Store Foundation's goal is to make AppCoins available for everyone, and that's why users that don't own APPC can make payments with credit cards.

Below you can see a live log of express conversion exchange transactions. Every time a user makes an in-app purchase with a credit card, we will convert the fiat currency into APPC via (Conversion). Those APPC will then be transferred to the BDS account (Withdrawal). You can see all of these transactions in this page.

From October 1st, the App Store Foundation has an Incentives Program available for developers that integrate APPC billing system. With a 10,000 APPC reward at the moment of integrating and a weekly reward of 125,000 APPC, it’s a great opportunity for developers to see the advantages of distributing and monetizing apps through blockchain technology.
