When you have cryptocurrency wallets worth millions, how do you store them? The \"Gregersen-Gono Standard\" is one option.\
\
\"Cryptocurrency private keys are randomly generated, and immediately encrypted. The encrypted keys are then etched using a UV laser, onto polycarbonate cards. Private keys are not stored in digital form at all.\
\
The polycarbonate cards are then stored in custom, tamper-proof mini-boxes which are then sealed with a tamper-evident metal seal. The sealed mini-boxes are then stored within our UL rated Class II vault.\
\
To release the cryptocurrency, customers\' identities are carefully verified. A special decryptor device is then pre-authorized by 3 independent groups. After this authorization, the decryptor scans the polycarbonate card, unlocking the key and sending the funds automatically to the customer.\"\
