Is Bitcoin anonymous?

Not really. It's anonymous only until you start using it.

Is Bitcoin anonymous?

Bitcoin is used for buying drugs. Bitcoin is only used by criminals to finance terrorism, child abuse, or money laundering. Nerds use Bitcoin for shady or illicit activities. All these sentences are very common and accuse Bitcoin of something that is not true at all.

Yet, all of them have the power to dominate mainstream media. But they all come back to misunderstanding the answer to a straightforward question. Is Bitcoin anonymous?

Is Bitcoin anonymous?

If anyone wanted to facilitate any of the activities mentioned above, such as money laundering or terrorism financing, they would probably choose an anonymous tool or platform since it stops governments or law-enforcement organizations from preventing or punishing them for doing so. Thus, it makes sense for them to use tools that would lead to the privacy while sending Bitcoin.

Sadly for them, and luckily for everyone else, Bitcoin is not anonymous. 

Contrary to what mainstream media will say, Bitcoin does not hide all the information about transactions that would lead to complete Bitcoin privacy. On the contrary, Bitcoin has a publicly opened ledger called blockchain, where every single transaction that happened on-chain ever since the inception of Bitcoin in 2009 is recorded.

With blockchain, all the transactions occurring will forever be written in an immutable ledger and thus, cannot be changed. This simply means that if the transaction happens and is written in the blockchain, it cannot be changed or deleted. Once it happens, the transacted amount, the fee, the sending and receiving addresses will be imprinted on the blockchain, where they will stay forever.

DoJ and the Bitfinex hack

Probably the most recent example that shows best that Bitcoin and crypto as such are not as anonymous as many claims, is a fairly recent arrest made by the Department of Justice of the United States. Only a few weeks ago, DoJ seized bitcoins worth over 5 billion dollars that were traced back to Ilya Lichtenstein and Heather Morgan.

This couple is said to be behind the hack of almost 120 000 BTC from Bitfinex that took place in 2016 and at that time was worth about 72 million dollars. Since then, the couple was able to run from justice for almost six years, yet, it caught up with them. DoJ was able to track some of the bitcoin transactions back to the couple, and thanks to that, also got their hands on more than 94 000 BTC that were stolen in the previous hack. What does this tell us about Bitcoin?

Bitcoin is traceable, thus pseudonymous

Thus, Bitcoin is not anonymous because it leaves behind these little “breadcrumbs” of information about transactions that occurred. Bitcoin is mainly referred to as pseudonymous, which means that it does not provide complete privacy of the transaction, yet, it does not reveal the owner’s entity. It only shows the sending address, which is created from the strings of numbers and letters, and the receiving address, where the same logic applies. 

However, if the real-world identity is ever connected to the address of a wallet, the transactions will become traceable, and all the activity that is connected to the wallet, such as sending or receiving bitcoins, will be connected to the owner.

What you should know about KYC? 

Thus, contrary to popular opinion, Bitcoin is traceable. Especially if the user uses any form of KYC services (Know-Your-Customer). What this means is that if any exchange, service, or platform that offers any cryptocurrency services asks for the identification in the form of a passport, ID, or even a bank statement, it can connect the real-world identity with the cryptocurrency wallet.

If that happens, every single transaction that occurs from or to that address or the available wallet is then connected to the owner’s identity. And while this is not a problem for some people, some would like to protect their financial privacy. Not because they would be doing something illicit, just because having financial privacy should be the same as having any other type of privacy.

The fact that someone does not want to share their financial situation does not mean that they are automatically doing something illicit. If any stranger asked you on the street how much money you have in your bank account, would you be willing to answer that question honestly? If not, you just showed that having the right to have your financial state private to yourself is important.

Ben Weiss, CEO of a CoinFlip, a Bitcoin ATM operator, has, for instance, stated the following with regards to the Bitcoin and traceability:

“Bitcoin transactions are more traceable than cash, and it would be stupid to launder dirty money using Bitcoin.”

In fact, many Bitcoin experts are pointing out that Bitcoin is far less anonymous than cash. In the case of physical cash transactions, there are no traces of it ever happening. Whereas in the case of Bitcoin transactions, some information is always made public, making it possible to trace.

Lightning Network and anonymity

Yet, there are different ways to keep the wallets relatively anonymous. While some of them can be rather complicated and technical, other tools are relatively simple. One of them is, for instance, a Bitcoin ATM, which in some cases still offers a chance to buy Bitcoin anonymously. Usually, it is only to some amount, such as 1 000 dollars, but it can still provide an opportunity to get some bitcoins or satoshis without KYC.

Another, probably more straightforward option is the usage of Lightning Network (LN). Lightning Network is a layer-2 solution where transactions do not go directly to the blockchain. Without going too deep into the LN technicalities, LN can offer a simple way to move around some pocket money without any need for KYC or complicated skills. The only thing that is needed is any LN wallet such as Blue Wallet, Muun Wallet, Phoenix wallet, or countless others that are easy to download.

Yet, it needs to be stated that Lightning Network is still relatively new and can be subject to faulty transactions. Sometimes, some transactions will not go through, or there is not enough liquidity to move the capital around, which is a reason why as of now, it is only recommended to only send a few hundred dollars worth of transactions at most.

Finally, a proved method of enhancing Bitcoin's privacy is to use a Bitcoin tumbling service. A Bitcoin tumbler, also referred to as a Bitcoin mixer, is a service that restores the privacy when using Bitcoin.


Without any doubt, the answer to question "is Bitcoin anonymous", is No. Yes, it offers some kind of privacy, especially if the users are careful. However, mainstream crypto usage through centralized exchanges (learn about anonymous bitcoin exchanges) will almost certainly go through a KYC process, where any form of privacy is immediately compromised. Whether that is positive or negative is only up to you and what you believe in.

Crypto Mixers and the Fight for Privacy

Financial privacy is under increasing threat from stringent KYC and AML regulations. While these measures are intended to curb illicit activity, they also expose ordinary users to extensive surveillance and data collection, undermining their personal autonomy and security. As a result of these regulations, crypto mixers and privacy-focused wallets are being targeted, but what are the real consequences of losing financial privacy?

A message to US and EU users

With the recent pressure to eliminate blockchain privacy tools such as privacy wallets and crypto mixers, Whir is at a crossroads. Increased regulatory scrutiny, especially from regions with strict overregulation such as the United States (US) and the European Union (EU), has created significant challenges for crypto mixers. As a result, we have to make a difficult request to our valued users from these regions: we kindly ask you to refrain from using our CoinJoin service.

Crypto wallets disable CoinJoin

In recent years, the cryptocurrency world has seen a growing tension between regulators and privacy-focused services. Recent crackdowns on prominent players such as Tornado Cash and Samourai Wallet are sending shockwaves through the crypto industry and raising fears of over-regulation. The costs of oversight and control are high and, as usual, are passed on to ordinary users, who end up losing the ability to conduct crypto transactions privately.
