How do you store Bitcoin securely in the long term?

Holding cryptocurrencies is not easy. Smartphones get lost, hard drives can crash and online wallets get hacked frequently.

The safest way of storing cryptocurrencies long term is offline in a physical way. That’s why we developed Card Wallet - the professional cold storage solution.

Who produces the Card Wallet?

The Card Wallet is a co-production of Coinfinity and the Austrian State Printing House (OeSD). Coinfinity was the first Austrian bitcoin company and has stood for trust and values in the crypto world for many years. OeSD is an international leader in the production of secure documents and, among many other things, produces Austria's passports.
