Privacy And Nodes

Bitcoin's ledger is public. That transparency lets everyone verify supply and settlement, but it also means careless usage can reveal your financial history.

Address Reuse

Use a new receive address for every payment. Reusing addresses links payments together and lets senders inspect more of your activity than they need to know.

Wallets generate new addresses automatically. Use them.

Labels And Coin Control

Label coins by source as soon as you receive them. Later, labels help you avoid combining unrelated coins in a way that links identities.

Coin control is the practice of choosing which UTXOs to spend. Beginners do not need to micromanage every output, but they should understand that combining coins can leak information.

Your Own Node

When your wallet asks someone else's server for balances, that server may learn your addresses and IP address. Running your own node lets your wallet verify transactions against your own copy of the rules and chain.

A node does not make you anonymous by itself. It does reduce trust in third-party infrastructure and improves privacy when configured carefully.

Tor

Tor hides your IP address from services you connect to by routing traffic through a volunteer network. Many Bitcoin wallets and node tools support Tor.

Tor is not a substitute for good wallet hygiene. It protects network metadata, not seed phrases or address reuse.

KYC Links

If you buy from an identity-verified exchange, those coins may be linked to your identity. You can still improve future privacy with labeling, address hygiene, careful spending, and avoiding unnecessary public disclosure.
