# Bitcoin Custody Options (not exhaustive list)
Here are the main ways to custody bitcoin, from least to most self-sovereign:
- **Centralized Exchange** - Shared custody wallets (Coinbase, Kraken). Some like River and Swan* allow buying/holding but not deposits
- **Mobile Custody Apps** - Strike, Fold (simplified centralized custody) - for small amounts
- ** Mobile Bitcoin or lightning Wallets ** - good for small to medium amounts
- **Single-Signature Hardware** - Trezor, ColdCard (the word “wallet” is not right, these are transaction signers)
- **Self-Managed Multi-Signature** - 2-of-3 setup using Sparrow and hardware signers
- **Assisted (or Collaborative) Multi-Signature** — Companies like Unchained, Casa, or Swan hold 1 key, you control 2-4 keys plus backups
- **Multi-party, Multi-Signature** — All keys held by separate companies (like Onramp). Requires identity verification (video) to sign transactions
- **Bitcoin ETF** - This is in essence having a third party hold bitcoin for you. Self Custody is better, but this is an option that is better than fiat
**Important Considerations**
- Security (physical, digital, social engineering)
- Access & Recovery
- Counterparty Risk
- Estate Planning
