🪜 The Custody Spectrum

ETFs, exchanges, self-custody, multisig — and what you trade at each step

Five lessons on the one question that decides everything: who holds the key? From an ETF that never lets you touch one, through exchange IOUs and the hot/cold split, to multisig setups where losing a key isn't a catastrophe. Every rung gets its real pros before its cons — the goal is choosing your spot on purpose, not sliding to an extreme by default.

  3. 🏛️ Exchanges: Convenient, But You're Trusting a Company
    It feels like owning it. By default, you usually don't — yet.

Holding Your Own

Hot, cold, and the setups where one lost key stops being fatal.

  1. 🌡️ Self-Custody: Hot, Cold, and Hardware

    When one key is no longer a single point of failure — plus a recap.
