Privacy & Security

Staying safe and keeping your business your own.

• Address reuse

  Using one address twice ties your payments together for the whole world to see.

• Coin control

  Choosing exactly which of your coins a payment spends — and which stay separate.

• KYC

  The identity file attached to your exchange account — and to every coin you withdrew.

• Chain analysis

  The industry that reads the public blockchain to tie coins to names.

• Common scams

  The five pitches that steal the most bitcoin — all old cons wearing new clothes.

• Phishing

  Fake sites, emails, and "support" designed to harvest your seed words or logins.

• Verifying downloads

  Checking that wallet software is genuine before you trust it with money.

• Dust attacks

  Tiny unsolicited coins sent to bait your wallet into revealing its owner.

• Nodes & your privacy

  Whoever answers your wallet's questions learns your addresses. Your own node tells no one.
