Hot wallets vs cold storage
Hot wallets (phone apps, browser extensions) are connected to the internet — convenient for small amounts and spending, but higher attack surface.
Cold storage keeps keys offline. Hardware wallets are the most popular cold option for long-term holders: you sign transactions on a dedicated device while keys never touch your computer or phone.
Hardware wallets worth considering
No wallet is perfect for everyone. Match the device to your skill level, budget, and threat model. Below are three well-regarded options in the Bitcoin-only / Bitcoin-first space.
Coinkite
Coldcard
Air-gapped hardware wallet with a numeric keypad, PSBT support, and a strong focus on security for long-term holders.
Best for: Advanced users who want maximum security and don’t mind a steeper learning curve.
Blockstream
Blockstream Jade
Open-source hardware wallet with optional camera for QR signing and a competitive price point.
Best for: Beginners and intermediate users who want open-source firmware at a fair price.
Shift Crypto
BitBox02
Swiss-made hardware wallet with a minimalist design, microSD backup, and Bitcoin-only edition available.
Best for: Privacy-conscious users who prefer a simple, no-nonsense device.
Seed phrases and metal backups
Your 12- or 24-word recovery phrase IS your Bitcoin. Never photograph it, never store it in cloud notes, never type it on a website. Write it on paper initially, then move to a metal backup for durability.
One metal backup kit is enough for most people — store it separately from the hardware wallet itself.
Various
Metal Seed Backup
Stamp your recovery words into steel so backups survive fire, flood, and time better than paper.
Best for: Anyone storing meaningful amounts — paper backups are a single point of failure.
When to move off an exchange
A practical rule: once you would be upset to lose the amount, withdraw to self-custody. For many people that’s anywhere from $100 to a few hundred dollars — but only after you understand seed phrase responsibility.
