&gt; I do not accept the concept of “trust”, I don’t know those guys, why should I trust them? On the other hand, with BTC trust is not even considered to be a factor.<p>That is a strange argument. The value of Bitcoin comes from the trust people have on Bitcoin. If nobody trusts Bitcoin, it&#x27;s worthless except as a mathematical curiosity.<p>And after just a few more paragraphs, we see another instance of trust. The author describes leaving most of the money in a hardware wallet. That is, the author is trusting that the hardware is neither malicious nor buggy. A malicious hardware wallet could use kleptographic attacks to exfiltrate the private keys, or derive them from an attacker-controlled seed. A buggy hardware wallet could, for instance, have a &quot;stuck&quot; RNG (like a well-known OpenSSL fiasco), such that the generated private keys are predictable.<p>The author is trusting people he doesn&#x27;t know: the designers of the hardware wallet, the manufacturers of the hardware wallet (including workers at whichever factory manufactures the hardware), and even the postmen. Moreover, the author is not only trusting them to not be malicious, but also to not make mistakes (with crypto, even small mistakes can be deadly).<p>And there&#x27;s also at least one other problem the author didn&#x27;t consider, or at least didn&#x27;t mention: inheritance. If the author has an accident, what happens to the money? And what if the accident is not fatal, but leads to neurological sequels which render the author unable to access the hardware wallets?
