DARK TAPE - Sound Wallet Cassette
Already has a private key on it just like the famous casascius coin. Private keys generated on a cold computer using bitaddress. The DARK TAPE is unloaded there is no bitcoin asigned to this private key at the time of purchase.
The tape is 20min on each side. The private key is recorded on the first few min of the first side. This allows you space to record something after the key such as the words to your private key or 2FA seed as another back up. We recomend not recording on side B to improve the life span of the cassette.
Stored correctly magnetic cassettes can last up to 30 years, when you record on both sides after time there is a little bit of “mixing” between A and B due to gravity and magnetic forces.
