Merchants selling digital goods or expensive items internationally have noticed that a crypto option sometimes closes a sale where the card form does not. The plugin, the API, the admin user, and, in many setups, a wallet that cannot be reversed all become part of the store. If the wallet isn’t secure, a login isn’t protected, someone pays out on the wrong chain, a connector goes unused for months, or half the team can open the payment panel, you have built a hole instead of a feature. Tax offices also treat incoming crypto differently from country to country, and they expect records that card firms already hand you. If you send USDC to an address that expects it on a different chain, the money will be gone.
