Is Bitcoin Anonymous? Here’s the Complete Answer…

One of the main features people usually link to Bitcoin is anonymity, but is Bitcoin completely anonymous ? On the one hand, it is entirely anonymous. On the other, it is completely transparent and trackable since all transaction are recorded in a public ledger.

Bitcoin is what you’d called pseudonymous. Sending and receiving bitcoins is like writing under a pseudonym. In Bitcoin, your pseudonym is the address to which you receive Bitcoin. If your address is somehow linked to your identity it’s exposed.

Since all transactions on the Bitcoin network are recorded on the Blockchain people will now be able to know the amount of Bitcoins you own on this address, which addresses sent you money and which received money from you.

If for example you’re requesting donations on your website with a specific Bitcoin address – that address is no longer anonymous.

So what can you do to remain completely anonymous ?

First it’s best to use a new Bitcoin address for every transaction you conduct. This is a good start although this won’t guarantee complete anonymity. This is due to the fact that if you use multiple inputs for a transaction and one of these inputs comes from a compromised address – all of your input addresses will now be exposed.

In our recent guide: using Bitcoin anonymously we detail the exact steps to take in order to maintain the highest degrees of anonymity.

For improved anonymity you should use multiple wallets. Creating a new change address for your inputs can also improve anonymity as a new address will be created once you get back change from payments you’ve sent. This featured is supported by the Bitcoin Core client for example.

Additional less conventional methods include hiding your computer’s IP address, using mixing services which trade out your bitcoins for ones with a different history, using the TOR browser and connecting to the Internet via VPN.

      Hi Richard, thanks for your feedback! We are glad you found the information useful in this post.

  2. I can attest that using MultiBit can save you a lot of headache. I lost some Bitcoins before using this, as someone followed my trail and “relieved” me of my bitcoins. Now I try to use every little thing I can to be more protected.

  3. Love the option of getting your transactions mixed with other people’s and I’ve been using from the day it started.

  4. I was considered using multiple Bitcoin Wallets but wasn’t really sure if that was a smart move or just something that was not really needed. Now I know. I can’t believe we (Bitcoin users) are so easy to track if we aren’t careful!
