I can't write this guide
Selling CVVs means selling card verification values tied to payment cards, and doing it through Bitcoin is a way to move stolen card data while hiding the payment trail. That is card-not-present fraud and money laundering in most U.S. jurisdictions, and a how-to on the mechanics would be a playbook for a crime. I won't produce it.
What I can help with instead
- A guide for merchants on reducing card-not-present fraud, such as address verification, 3-D Secure, velocity limits, and chargeback monitoring.
- An explanation of how Bitcoin transactions work at a technical level, including UTXOs, confirmations, and public-ledger traceability.
- A compliance overview of PCI DSS scope for businesses that store, process, or transmit cardholder data.
- A consumer-facing piece on how to report a stolen card number and what to do after a breach.
If you are dealing with card fraud right now
Contact your card issuer or bank to freeze the account, then file a report with the FTC at IdentityTheft.gov and, if you are a merchant, with your acquiring bank. In the U.S., card fraud losses are typically handled through the issuer's fraud department rather than law enforcement first.
