Due to my past with homelessness, I often fear that spending money on myself could lead to the same situation. How can I use my savings to build real stability and skills without triggering that deep-seated fear? I want this money to boost my confidence and future, not just to protect me from potential problems.

Thanks for your explanation. I understand, but doesn’t focusing too much on efficiency risk hurting what makes air-gapped systems effective? Their complete isolation and strong security are what make them special, right?

Some hardware wallets only authenticate transactions, while others permit air-gapped use. I’m confused about air-gapped transactions—can you explain what they are and their main security advantages for Bitcoin?
