Sound Wallet can keep your Bitcoins secure with vinyl-based encryption

For digital currency users looking to secure their e-fortune, one project is offering a new way to store private keys: on vinyl.
Sound Wallet promises to store users’ private keys as encrypted audio files across a range of products – including CDs and 7-inch vinyl disks.
Theodore Goodman, the brains behind the project, said he used the iconic format as it is the ‘ultimate archive medium’.
