Part 4/10:
Environmental Risks
Physical damage such as fire, water, corrosion, or natural disasters can destroy your backup. For example, paper can be ruined by floods or accidents, so materials resistant to these elements are preferable for long-term storage.
Physical Attacks
A person might be motivated to steal your crypto by threatening or even physically harming you (e.g., the classic “$5 wrench attack”). Minimizing verbal disclosure of your holdings and keeping a low profile reduces risk. For higher security, using multiple hardware wallets, each protected by distinct passphrases, helps fragment your assets so an attacker can't easily drain your holdings with a single breach.
