Bitcoin is pseudonymous, not anonymous. Every payment is public forever, and names stay hidden only until something links them to you. Learn how.
Public by design
Every Bitcoin transaction ever made is visible to anyone, forever. You can browse them in our explorer. What the blockchain does not show is names: just addresses, amounts and links between transactions.
That's called pseudonymous: like writing under a pen name. The pen name is public, and if anyone learns who is behind it, they can read the whole history.
How identity leaks
- Exchanges that verify your identity know which addresses you deposited to and withdrew from.
- Address reuse links many payments together.
- Spending patterns, such as combining coins in one transaction, let analysts guess which addresses belong together. See Chain analysis heuristics.
- Network data: a node that sees your transaction first may learn your IP address.
Good habits
- Use a new receiving address for each payment (most wallets do this automatically).
- Use Coin control so you don't merge coins you want to keep separate.
- Run your own node so your wallet doesn't reveal addresses to someone else's server.
What anyone can see
For any address you paste into MyBitcoinExplorer's search, the whole world can see every payment in and out, every amount, and when. That is by design: public data is how every node verifies the rules.
Tools that improve privacy
| Tool | What it helps |
|---|---|
| New address per payment | Stops payments being linked by address |
| Coin control | Avoids merging coins from different sources |
| Your own node | Stops a server learning your addresses |
| CoinJoin | Mixes inputs from many people in one transaction |
| The Lightning Network | Many payments never touch the blockchain |
Privacy is not secrecy from the law
Privacy tools protect you from strangers, data brokers and thieves who look for wealthy addresses. Laws on reporting and taxes still apply, and some services restrict coins that went through mixing.
Key takeaways
- Bitcoin is pseudonymous: everything is public, but not labelled with names.
- Exchanges, address reuse and spending patterns can link addresses to people.
- Fresh addresses and coin control improve privacy.
Common questions
Can the police trace bitcoin?
Often, yes. Because the ledger is public, investigators can follow payments and link them to identities through exchanges and other data.
Does a new address per payment make me anonymous?
It helps a lot, but spending patterns and exchange records can still link addresses. Privacy is a set of habits, not a single setting.
Can someone see my bitcoin balance?
If they know one of your addresses, they can see what that address holds. A wallet with many addresses is harder to total up.
Does Bitcoin hide my IP address?
Not by itself. Running your node over Tor or I2P hides it from peers.
