Whenever you wish to make a transaction along with your property (like shifting them or promoting them), you merely enter your 6-character (minimal) salt and your 30-character (minimal) passphrase into your Bitfi machine. Then, Bitfi calculates your non-public keys for any given token on-demand, then instantly expunges that personal key.

Due to this distinctive system, your non-public keys are by no means completely saved on the Bitfi, by no means left on the Bitfi, and are by no means despatched in a transmission from the Bitfi machine to the blockchain to manage your property.
