Hi, I have bought some cracked walmart gift card from some bitcoin marketplaces. But im just wondering how come they can get those codes? they are saying its cracked account. But, just say that they can cracked the account and get into the account, how is it possible for them to get the card number and PIN of those gift card? Im pretty sure thats not the carded card because the amount is like $5.36 or $3.78 .
