Privacy basics for bitcoiners

Understand first: How a bitcoin wallet works

Good privacy starts with ordinary habits: protect your logins, verify requests, and be careful about who knows what you hold.

Bitcoin's base blockchain is public. Once an address is linked to you, its transactions can reveal more about your finances. Lightning payments are not all recorded individually on that public ledger.

Five habits worth building

Use a separate email for money

Keep exchange and financial logins separate from shopping, newsletters, and social accounts. Secure the email account too.

An unexpected bitcoin message to your everyday address deserves scrutiny. The separate address helps you spot suspicious messages; it does not prove any message is genuine.

Proton Mail offers a free option. Other reputable providers can work too.

Strengthen your sign-ins

Use a security key or passkey where supported, or an authenticator app for two-factor authentication. Save recovery codes safely before disabling an older method. Any second factor is better than none.

SMS codes are vulnerable to SIM swaps. Ask your carrier about a port-out lock or account PIN. It reduces risk without eliminating it.

Give every account a unique password

Use a password manager to create and save long, unique passwords. Protect the manager with a strong master password and multifactor authentication.

Keep hardware-wallet recovery words out of the manager and cloud storage.

Know what a VPN does

HTTPS already encrypts traffic between your device and the website. A reputable VPN adds a tunnel to its own server and can reduce what the local network sees, but shifts trust to the VPN provider.

It cannot make a scam site safe or hide your identity from an exchange you log into. Keep your software updated and verify the site address. A VPN is an optional privacy tool, rather than a substitute for these habits.

Share less about your holdings

Avoid posting balances, wallet screenshots, or details about where you keep backups. Give trusted people the information needed for your recovery plan through a secure process.

You do not need to advertise the contents of your safe.

Protect transaction privacy

Use a fresh receiving address when your wallet offers one. Reusing addresses makes activity easier to link. A fresh address helps, but does not make bitcoin anonymous.

An exchange can link a withdrawal address to your account. Understand that connection before sharing the address elsewhere.

Check the complete destination address on the hardware wallet's screen. Copied text and QR codes can both lead to the wrong destination.

Spot the scam before you respond

• Never give a support agent your recovery words, password, or sign-in code.
• Open your exchange through a saved bookmark or a verified address.
• Get wallet updates through the official app or maker's site.
• Treat urgent warnings as a reason to pause and verify independently.

Someone asking for your recovery words is asking for your bitcoin.

Make one improvement today

Secure your financial email, strengthen an exchange login, or replace a reused password. Then review your recovery codes and remove public posts that reveal your holdings.

Privacy improves with small habits you keep using.
