Question
Why can't I use a credit card to purchase Digital Collectibles? 
Answer

Blockchain copies of books, also called Digital Collectibles or NFTs, must be purchased using the currency for the blockchain on which these copies are minted and where the purchase is validated.

Unlike regular digital books, Digital Collectibles are created during the minting process by a blockchain transaction, and each resale is tracked and validated on this digital ledger. The currency must match the blockchain. For example, a Digital Collectible minted and validated on the Polygon blockchain must be paid for using MATIC. A digital collectible minted and validated on the Ethereum blockchain must be paid for using ETH.

Cryptocurrency such as MATIC and ETH can only be purchased in an Exchange, such as Coinbase or Transak. CryptoComics is not a currency exchange, but is a Marketplace for Digital Collectibles. Learn how to purchase MATIC or other currencies to use in the CryptoComics Marketplace here.
