Central to the single egg basket design is the Ai-Fi Incognito Cloud where a variety of digital valuables are locked away in various types of Krypton Tokens. Each token is protected by a private/public key pair, retrievable through a passphrase and client-side salt, of customizable cryptographic strength comparable to or stronger than Bitcoins on the blockchain. This is how your egg basket is made indestructible.
Your crypto wallets are protected by 12 or 24 words of seed mnemonics, making up the all-or-nothing total worth of your digital assets. It's time to move them out of the stone age of paper records and store them into the Ai-Fi Incognito Cloud as a Krypton Token with encryption strength higher than Bitcoins on the blockchain.
Hardware wallets are perceived secure, as they may be kept in your pants pocket and less susceptible to malware attacks, until they are targeted or lost. Besides, their recovery mnemonic words still need a home. Find out how an all-software Ai-Fi Counterseal solution takes care all your worries.
If you insist on using a paper vault, introduce some redundancy to protect those pieces of papers, or mix and match paper with "Krypton Tokens" in the Ai-Fi Incognito Cloud. Split your individual secret into multiple "shares", and distribute them in multiple locations or vaults. Make sure you don't lose the majority of the secret shares.
