Bitcoin Security Levels: How safe are your sats? Not all Bitcoin holders have the same level of security. Here are 6 Bitcoin Custody security levels in one post. Level 0: Bitcoin on an Exchange 💀 If your coins are on an exchange, they are not yours. 🚨 Risk: Hacks, insolvency, frozen accounts. 🔑 Not your keys, not your coins! Level 1: Hot Wallet on Mobile or Desktop 🔥 You own your private keys, but they are online = vulnerable. ✅ Better than an exchange, but not secure for long-term storage. 💡 Recommended wallets: BlueWallet, Sparrow. Level 2: Hardware Wallet with Shitcoin Support (or closed source Hardware Wallet) 🔐 More secure than hot wallets, but: 🚨 Many hardware wallets (e.g. Ledger) support altcoins and are not fully Open Source. ❌ Unnecessary attack surface! Level 3: Bitcoin-Only Hardware Wallet ✅ No altcoin support = reduced attack vectors. 💡 Recommended wallets: BitBox02 ➡️ Want even more security? Airgapped wallets! 👇 Level 4: Bitcoin-Only + Airgapped Hardware Wallet ✅ Even fewer attack vectors since transactions are signed via QR code or SD card. 💡 Recommended wallets: Foundation Passport, Coldcard, SpecterDIY Level 5: Single Seed + Passphrase (Cold Storage) 💪 Extra security: Even if someone finds your seed, they can’t access your funds without the passphrase. Important: Never store your passphrase digitally 🔐 Recommended wallets: Foundation Passport, SpecterDIY 🚨 Warning: Higher risk as you now have two single points of failure. Your setup must be well thought out. Level 6: Multi-Sig Cold Storage 🛡️ Multiple keys required to spend = maximum protection. ✅ No single point of failure. 👨‍👩‍👦‍👦 Ideal for families or businesses. 🔐 Can be customized: ➡️ 2-of-3, 3-of-5, mixed hot & cold wallets. 💡 Recommended solutions: Unchained Capital, Sparrow, Blockstream Jade That's a wrap!

Back in the beginnings of Bittr in 2018, we initially didn’t work with XPUBs. But we saw the benefits and implemented them in 2019. An XPUB gives you better privacy and security. By using it, each deposit goes to a new address. That makes it harder for others to find out how much Bitcoin you own. Today we even refuse to accept XPUBs that have already been used for other transactions since this would compromise your privacy.
