1. Wallet types
Bitcoin wallets are broadly divided into hot wallets and cold wallets. Hot wallets are internet-connected; cold wallets are offline.
💡 Core principle
Hot wallets for transactions, cold wallets for storage.
Keep small amounts used frequently in a hot wallet and larger long-term holdings in a cold wallet.
2. Hot wallets (software wallets)
Mobile wallets
- Trust Wallet — Described in the source as Binance's official wallet, with multichain support and an integrated dApp browser.
- Exodus — An attractive, beginner-friendly interface with desktop integration.
- Blue Wallet — Bitcoin-focused, with Lightning support as described in the source.
Browser extensions
- MetaMask — Widely used in the Ethereum ecosystem for DeFi and NFTs, with a Chrome extension.
- Phantom — A major Solana wallet with a clean interface.
- Rabby — Multichain support and transaction simulation.
Hot wallets offer convenience and quick access, but their internet connection makes them vulnerable to hacking.
3. Cold wallets (hardware wallets)
Cold wallets store private keys on a physical device about the size of a USB drive. The source describes their separation from the internet as making remote hacking extremely difficult.
Hardware wallets listed in the source
- Ledger Nano X — A popular hardware wallet with Bluetooth and support described as 5,500+ coins; approximately $149.
- Trezor Model T — Touchscreen, open-source design and strong security; approximately $219.
- Ledger Nano S Plus — An entry-level hardware wallet with USB-C; approximately $79.
✅ Precautions when buying a hardware wallet
• Buy from the official website, not secondhand or open-market sellers.
• Do not use a device showing signs of prior opening.
• A prewritten recovery phrase means the device is 100% compromised.
4. Wallet-selection criteria
- Holdings below $1,000 → The source considers a mobile hot wallet such as Trust Wallet or Exodus sufficient.
- Holdings of $1,000–$10,000 → A hardware wallet such as Ledger Nano S Plus is recommended.
- Holdings above $10,000 → The source treats a hardware wallet such as Ledger Nano X or Trezor as essential.
- Frequent DeFi or NFT use → Connect MetaMask with a hardware wallet.
- Bitcoin-only holdings → Blue Wallet or Ledger.
5. Managing the seed phrase
The seed phrase or recovery phrase is a wallet's master key, made of 12–24 English words. It lets you restore the wallet elsewhere.
🚨 Seed-phrase rules
• Never store it digitally: no screenshots, notes apps or cloud copies.
• Write it on paper and keep it in a safe or secure place.
• Never disclose it to anyone, including support staff, developers or friends.
• Websites, apps or DMs asking you to disclose it are 100% scams.
6. Security checklist
- ✅ Enable 2FA, using Google Authenticator.
- ✅ Back up the seed offline, written on paper and stored safely.
- ✅ Use only official websites and apps, checking the URL.
- ✅ Do not trade over public Wi-Fi.
- ✅ Keep larger holdings in cold storage.
- ✅ Regularly revoke approvals granted to connected dApps.
