The Digital Vault: Crypto, Passwords, and Cybersecurity
The Digital Vault: Crypto, Passwords, and Cybersecurity
You protect your physical gold in a vault, but your Bitcoin is on a shaky exchange app. How to build “Institutional Grade” security for your personal digital assets and ensure your heirs can find the keys.
Executive Summary
- The Exchange Risk (Not Your Keys): Leaving $5M of Crypto on Coinbase or Binance is suicidal. If the exchange goes bankrupt (like FTX) or gets hacked, you are an **unsecured creditor**. You own nothing but a claim.
- The Solution (Cold Storage): You must move assets to **Self-Custody**. This means using a Hardware Wallet (Ledger/Trezor) that stores your Private Keys offline.
👉 The Rule: Your keys must never touch a device connected to the internet. - The “Dead Man’s Switch”: The biggest risk in self-custody is not hackers, but **death**. If you die and no one knows your 24-word seed phrase, the money is gone forever. You need a “Digital Inheritance Plan” (e.g., a seed phrase split into 3 parts, stored in separate safety deposit boxes).
The “SIM Swap” Attack
The Weakest Link: Hackers don’t break your password; they call Verizon pretending to be you. They transfer your phone number to their SIM card, intercept your 2FA SMS codes, and drain your bank.
👉 The Fix: **NEVER use SMS for 2FA.**
👉 The Standard: Use a hardware key like **YubiKey** or an authenticator app (Authy/Google) installed on a dedicated offline device.

“In the digital age, ‘Possession is 10/10ths of the law.’ If you don’t hold the private keys, you don’t own the asset. Security is inconvenient by design; if it’s easy to access, it’s easy to steal.”
