Anonymity Bitcoin Mixers: Money Laundering or Anonymity Protection?

[Fixxx]

During the creation of cryptocurrency, the "electronic asset" was conceived as something safe and completely anonymous. However, in practice, this idea has only been partially realized. For example, working with cryptocurrencies remains outside the control of government structures (as cryptocurrency still lacks clear regulation from banks and states); nevertheless, the records in the Bitcoin blockchain reveal information about transactions to all participants in the network. Without a signature, cryptocurrency transfers remain visible to other users and they can still be identified, albeit not easily, due to the transparency of the Bitcoin blockchain. Bitcoin mixers, such as those mentioned, have helped ensure anonymity for transactions. Now, if users need a truly anonymous transfer of funds, they can easily secure it.

The Concept of Bitcoin Mixers​

​

Bitcoin mixers are often referred to as internet resources that allow users to conduct the most secure and anonymous transactions in the Bitcoin network. With the help of mixer services, tracking a transaction becomes impossible, even when it's recorded in the public blockchain. The principle of operation of such services is that, when transferred from sender to recipient, cryptocurrency doesn't go directly to the recipient's account. First, Bitcoin is moved to a common wallet of the mixer and only after mixing with the funds of other users does the cryptocurrency reach the recipient. Often, the transfer may arrive at the recipient either in full (if the amount is small) or in parts (in the case of large payments). This way, it becomes easier to hide the path of the cryptocurrency and make the transfer as anonymous as possible. All Bitcoin mixers are conditionally divided into two main types: centralized and peer-to-peer.

• Centralized mixers belong to the first generation of mixing services. In such mixers, the quality of anonymity often depends on the total number of users, while the responsibility for the security of the service lies entirely with its administration.
• Peer-to-peer mixers represent a more advanced version of mixers. In this case, anonymity is ensured without the intermediary influence of developers.

The Process of Mixing Cryptocurrency​

The algorithm of Bitcoin mixers is extremely simple:

1. First, the money arrives at the site from different users. Once the funds are on the portal, they are mixed using built-in algorithms and then sent to the recipient's wallets. The mixing that occurs in the process is what gives these services the name "mixers".
2. After that, the money is sent to the recipients. However, it's important to remember that the vast majority of such sites charge a service fee.
3. As a result of mixing, it becomes practically impossible to trace the path of the cryptocurrency and identify its original owner.

Features of Working with Cryptocurrency Mixers​

Like all similar intermediary services, Bitcoin mixers have their own features that are also important to consider during operation.

• Speed of Operation: It's evident that when working with Bitcoin mixers, funds go through several transfers, which takes additional time. First, the cryptocurrency enters a common pool of coins, then a miner confirms its transfer and only after that is the coin transferred to other wallets.
• Additionally, the speed can be affected by the number of transactions - as mentioned earlier, very large amounts may be transferred in parts, which increases the number of transfers.
• Conversely, the fact that such services do not require any documents from users can speed up the process. At the same time, this can also be a downside, as it makes it harder to determine how trustworthy a particular service is.
• The speed of some mixers is time-limited. For example, if a service aims to enhance confidentiality, it will not store information for more than 72 hours. For instance, a generated address will only work within the system and only for a day, and it will no longer be possible to receive payments to the same address.

During the process, it is important to remain cautious and carefully read the messages sent by the site. For example, you should keep an eye on messages from the service: important information such as guarantee letters, wallet addresses and special codes that can prove ownership of the funds may be in your email. This information may also be useful for communication with technical support if necessary. Therefore, it's crucial to review all emails sent to you by the Bitcoin mixer to avoid accidentally deleting something important.

Risks of Working with Cryptocurrency Mixers​

Theoretically, all mixer sites should operate correctly and assist users. However, not all such sites are characterized by perfect operation. That is why, before starting any collaboration, it's important not only to choose a convenient service but also to eliminate all possible drawbacks of low-quality Bitcoin mixers.

• Risk of Scam: Bitcoin mixers often attract the attention of scammers. It's important to remember that such sites usually operate on user trust, which means that anyone could be behind a particular service. Therefore, all mixing services should be thoroughly checked: verify the service's reputation among other users, read reviews and compare ratings ofthe mixing services.
• Money Laundering: The risk of accidentally being suspected of money laundering is actually quite low, but it exists and should not be overlooked.
• Clustering Analysis: This is a special technique that helps to decipher many known services. Such algorithms have been created by companies like Bitfury and Chainalysis. Through clustering analysis, it becomes possible to identify Bitcoin addresses that are interconnected, even through a mixer.

How to Choose a Reliable Cryptocurrency Mixing Service​

Of course, each Bitcoin mixer has its own features, which may be necessary for one user but not important for another. Nevertheless, there are several key characteristics that any reliable service should possess. Before choosing an appropriate Bitcoin mixer, it's worth paying attention to the following factors:

• Service Reputation: As mentioned earlier, the mixer should receive positive feedback. Be cautious of services that have only positive comments from users - sometimes scammers may write such comments on demand just to lure users in. Pay attention to large forums and try to objectively assess each review.
• Phishing Sites: Alongside feedback, you can check for the presence of phishing sites. These are copycat sites that disguise themselves as reputable sites to deceive users. If the mixer you have chosen has such a duplicate, you should be very careful when depositing funds, verifying the authenticity of the site.
• Blockchain Analysis: The aforementioned issue of clustering analysis allows analysts to draw parallels between user wallets and the services used. You can check if the Bitcoin mixer you have chosen is on a "marked" list through a specific link.
• Quality Technical Support: It's best if such user assistance is available 24/7. You can contact support even before starting cooperation to clarify a couple of basic questions - such as regarding user service or the reliability of the service.
• Too Small Cryptocurrency Pools: This problem is often encountered with newer services that have not yet gained popularity and filled their Bitcoin reserves. Thus, if the amount you wish to deposit exceeds the mixer’s reserve, the entire sum will be processed and transferred only in parts.

How to Enhance the Anonymity of Your Transfers​

In life, various situations can arise, and sometimes a user simply needs to achieve maximum anonymity. Even if you have already used mixing services, there are still several ways to enhance the effect and make the transfer even more confidential:

• Make Multiple Deposits Instead of One: For this, the main amount is simply divided and sent to the recipient in smaller batches. This way, correlating several different payments with a specific recipient becomes much more difficult than doing the same with one large transfer.
• Use Different Bitcoin Wallets: If conditions allow, each monetary batch can be sent from different Bitcoin wallets. This will complicate the tracking of the funds.
• Delay Withdrawals: If possible, don't withdraw the received funds immediately. The longer the time between sending the money and withdrawing it, the harder it becomes to establish a connection between the money and the individuals sending and receiving it.
• Withdraw Through Different Addresses: Just as with sending money from different cryptocurrency wallets, you can also withdraw funds through different addresses. In this case, a time delay can also benefit anonymity.

It's important to remember that if the transaction is not a simple transfer from person to person, but, for example, a purchase online, maintaining anonymity will be more challenging - during such operations, it's much easier to identify the holder of the coins.
