The digital age has brought us unprecedented levels of convenience and connectivity, but also new challenges to our privacy rights.

Payment privacy has become a major concern for many people who value their right to conduct financial transactions without undue scrutiny or interference. With the rise of cryptocurrencies, in particular bitcoin, people have been able to conduct financial transactions with a higher degree of privacy than was previously possible with traditional banking systems. But the truth is: bitcoin is far from anonymous.

The truth about the anonymity of Bitcoin

Despite its pseudonymity, bitcoin transactions are recorded on a public ledger called the blockchain. This means that all bitcoin transactions are public and can be traced back to the original sender and receiver addresses. While these addresses do not reveal the identity of the individuals behind them, they can still be used to track and analyze transactions.

Onchain analytic companies specialize in tracking and analyzing bitcoin transactions on the blockchain. These companies use various techniques to identify patterns in bitcoin transactions, and link addresses to specific individuals or entities. For example, they can track the movement of funds between addresses and use this information to identify the common owners of those addresses. Onchain analytic companies can be used by law enforcement agencies to track down criminals who use bitcoin for illegal activities. They can also be used by financial institutions to comply with regulations and monitor their clients' transactions for suspicious activity.

However, the use of on-chain analytics raises concerns about privacy and the fundamental principles of bitcoin's pseudonymity. Some argue that the use of on-chain analytics goes against the decentralized and anonymous nature of bitcoin, while others argue that it is necessary to prevent illegal activities such as money laundering and terrorism financing.

Bitcoin mixer or bitcoin tumbler appears to be at the center of this hotly debated topic. These coin-anonymizing services allow users to mix their coins with those of other participants, making it impossible to trace their source. However, due to the use of bitcoin mixers for illicit purposes, coin-mixing services have become a controversial issue, raising questions about the legality of their use.

ChipMixer and recent Bitcoin mixers seize

In recent years, law enforcement agencies have become increasingly concerned about the use of bitcoin mixers to conceal the source of funds in crypto transactions. One notable example is the case of Tornado Cash, a popular bitcoin mixer that was seized by authorities in August 2021. The operators of Tornado Cash were accused of facilitating money laundering and other illegal activities by allowing users to mix their bitcoins with those of others, making it difficult for chain analytic companies to track the source of the funds.

The Tornado Cash case is just one of many examples of law enforcement agencies cracking down on the use of bitcoin mixers. In recent years, there have been several high-profile cases of bitcoin mixers being shut down and their operators facing criminal charges. This has raised concerns among bitcoin users who value their privacy rights and are looking for ways to protect their financial transactions from prying eyes.

This week, on Wednesday, international law enforcement agencies cracked down on another cryptocurrency platform, ChipMixer, accusing it of aiding in obscuring digital currency transactions for drug dealers, Russian military hackers, and North Korean cybercriminals. According to the U.S. Department of Justice and Europe's Europol police agency, the website laundered over $3 billion worth of cryptocurrency.

Are Bitcoin mixers only used for illegal activities, or is it all about control? Where is the truth?

The seizure and shutdown of the bitcoin mixing service have been met with negative reactions from the cryptocurrency community. Many authorities, like Coin Center, argue that the use of mixers is a legitimate way to enhance privacy and protect against surveillance and censorship.

Coin Center is a cryptocurrency advocacy group that supports the development and adoption of cryptocurrencies and blockchain technology. In the case of Tornado Cash, a privacy-focused Ethereum mixer, Coin Center argued in favor of its legality and importance for preserving financial privacy.

One of the main arguments used by Coin Center was that Tornado Cash is a tool for preserving financial privacy, which is a fundamental right of individuals. They argued that financial privacy is important for protecting individuals from surveillance and discrimination, as well as for promoting financial freedom and innovation.

Coin Center also argued that Tornado Cash is not inherently illegal, as it does not directly facilitate illegal activities such as money laundering or terrorist financing. They argued that using Tornado Cash is similar to using cash, which can also be used for legal or illegal activities but is not inherently illegal.

Additionally, Coin Center argued that Tornado Cash should not be held responsible for the actions of its users as it is a decentralized and open-source project that does not control or monitor its users' transactions. They also argued that regulating or banning Tornado Cash would not be effective in preventing illegal activities, as it would simply drive them to other, potentially more dangerous, methods of laundering or hiding funds.

As the final result, Coin Center sues the Treasury Department for outlawing Tornado Cash. "The Biden Administration criminalized the use of Tornado Cash, an open-source software tool that helps Americans maintain their privacy while using cryptocurrency and related assets," states the 36-page lawsuit.

The complaint asks that Tornado Cash be removed from the sanctions list and that the Treasury Department be prevented from taking action against "ordinary Americans exercising their self-evident and fundamental right to privacy. Will similar steps take place in the case of the recently sized ChipMixer?


The use of bitcoin mixers to obscure the source of funds in transactions is a controversial issue that raises questions about privacy rights and the privacy of financial transactions. From a legal perspective, the use of bitcoin mixers is not necessarily illegal, but it can raise red flags for law enforcement agencies and regulatory authorities. If the use of a bitcoin mixer is found to be linked to criminal activity, such as money laundering or terrorist financing, the users of the mixer can be subject to criminal charges. If you are considering using a bitcoin mixer, it is good to research the legality of bitcoin mixers in your country to be sure that you are not breaking any laws.
