I use many methods and each one with a backup in another method, in another location.

But most important is to split all the stash into 3 levels: hold, cache, spend. https://postimg.cc/vg5Sf85D

As methods I use:

• password managers (Keepass + Bitwarden self custody) on different encrypted USB sticks and also on different remote private NAS.
• steganography (embed words into images)
• TailsOS USBs with encrypted persistent partition where is stored a copy of a password manager file. This is for emergency and traveling.
• one of my substack guides contain inserted 12 words from a wallet. Find it if you can.
• I put 12 words on 12 mountain peaks. Me and my daughter are the only ones knowing the order and location.

I do not use anymore hardware wallets. I gave them away years ago. I know what am I doing so those are not useful for me.

All these explained in one of my oldest guide: https://darthcoin.substack.com/p/bitcoin-be-your-own-bank-think-like
