Answer first: there is no legitimate website that sells CVV or CVC data for bitcoin. A storefront that advertises card verification values for sale is a criminal carding marketplace, and every listing on it is stolen property. Card issuers, processors, and merchants never resell verification values, and bitcoin appears in these listings because confirmed transfers cannot be reversed.

How a carding storefront works

These sites copy the layout of an ordinary online shop: card numbers, expiration dates, and CVV values as inventory, priced by card brand, issuing bank, and claimed balance. Bitcoin is the preferred payment rail because a confirmed transfer cannot be charged back. Sellers use escrow accounts, automated delivery bots, and invite-only forums to keep researchers and law enforcement at a distance.

The inventory comes from skimmers on fuel pumps and ATMs, phishing pages, breached merchant systems, and malicious scripts on checkout pages. A card can sit in a listing while its owner still carries the physical plastic.

Why buying on those sites is a losing trade

Most carding shops are exit scams. Buyers send bitcoin and receive nothing, or receive numbers that were canceled days earlier. Payment also leaves a permanent public record on the blockchain tied to the buyer's wallet, and US law treats the sale and purchase of stolen card data as a felony under 18 U.S.C. § 1029. There is no version of this transaction where the buyer holds clean title to anything.

Check whether your own card data is exposed

  1. Open your last three statements and match every charge to a receipt you recognize.
  2. Search your email for breach notices tied to any merchant where the card is saved.
  3. Review saved payment methods in your browser and phone wallet, and delete cards you no longer use.
  4. Turn on transaction alerts for every purchase above a threshold you choose.

Protect your CVV on every purchase

  1. Type the merchant address yourself instead of following a link from a message.
  2. Check that the checkout page shows a padlock and the exact domain you expect.
  3. Enter the CVV only on the payment form, never in a chat, email, or phone call.
  4. Use a virtual or single-use card number for subscriptions and unfamiliar sites.
  5. Keep the physical card turned face down and cover the keypad at terminals.
  6. Decline to let anyone photograph the front and back of your card.

If your card was charged without your approval

  1. Lock the card in your banking app to stop further authorizations.
  2. Call the issuer using the number printed on the back of the card.
  3. Request a new card number and a new CVV, not just a replacement card.
  4. File a report at IdentityTheft.gov and keep the reference number.
  5. Report the incident to the FBI Internet Crime Complaint Center if a criminal site was involved.
