Anonymity and decentralization are the key differences between cryptocurrencies and fiat money. But it is worth clarifying that all data on completed transactions is still stored and reflected in the blockchain registry, which allows you to track the path of each unit to the final location of its storage. In this regard, recently services and programs aimed at tracking operations within the system have been actively developing.

What is a bitcoin mixer?​

The indirect anonymity of Bitcoin has misled many users. Often, some participants in the system use the blockchain to accept not entirely legal payments or evade taxes. Even if all received transactions are completely legal, it is worth thinking about the anonymity of transactions, since with basic knowledge of blockchain technology, any user can track transfer data, find out the current balance and see where funds are stored and how they are withdrawn , which makes users vulnerable to fraudsters and regulatory authorities. In order to confuse the traces of transactions, a lot of methods are used, and special services have been developed - bitcoin mixers.

Bitcoin mixer is an anonymization service that makes it difficult or impossible to track transactions on the blockchain by dividing transactions into small amounts and moving them multiple times between different addresses.

Thus, users can enter coins assigned to one transaction into the mixer and withdraw completely different ones, while there will be a huge number of transactions between tokens, which will break the identification links with each of the participants.

Types of mixers​

All transaction anonymization services are divided into two types according to their operating principle.
  1. Centralized Bitcoin mixers are the first generation of services where the level of anonymity depends on the total number of users, and the security of use depends entirely on the professionalism and honesty of the service developers.
  2. Peer-to-peer Bitcoin mixers are an advanced model of centralized services that enable anonymization without the need for intermediary cooperation from developers.

How a Bitcoin Mixer Works​

When using centralized bitcoin mixers, anonymization of funds is achieved by mixing all transactions received from users. So the user sends his funds to the service, pays the established commission fee and receives exactly the same amount of funds, but only in other coins.

When mixing, all funds are split into small parts, and then randomly sent to wallets created by the service. This operation can be repeated dozens of times, and only after the coins are sent to the participant's specified address for receipt. The service must be reliable and technically secure, since this method of mixing is associated with the risk of theft of sent funds by platform developers, and insufficient technical security can become the basis for hacker attacks and break-ins. In addition, there is no guarantee that the service does not keep records of transactions.

Peer-to-peer mixers were developed as an alternative to the flawed model of centralized Bitcoin mixers. Bitcoin Tumblr in this case serves as a platform where users who want to anonymize funds can interact without an intermediary. To do this, several users unite in a peer-to-peer group and form a transaction, which goes through several stages before being sent to its destination from one user to another. None of the participants in the transaction knows any data about other users and the stages of mixing, and the absence of the service's participation in mixing eliminates the possibility of theft of participants' funds. Anonymous transactions are paid out randomly for a random number of coins, which add up to the amount required for payment.

Why is it necessary to use a mixer?​

Everyone has heard about the anonymity of Bitcoin, but few people know that it is practically a myth. Since the developers put a completely different meaning into this concept than modern token holders, who believe that all their transactions on the network are not identified. Bitcoin anonymity lies in the absence of the need to enter personal data and the absence of system control over transactions and their purpose. But the blockchain itself is a database that stores the history of all completed transactions. Of course, the blockchain registry does not contain personal data of transaction participants, and the Bitcoin wallet address is not personalized.

At first glance, this looks quite safe and anonymous, because the blockchain does not provide any personal data about the coin holders. However, once you link your data to any transaction, for example, pay for home delivery of goods or withdraw funds to a card, all transactions in the system can become personalized when tracked by regulatory authorities. This already provides the opportunity to track the method of earning, depositing and withdrawing funds, as well as all payment purposes and existing savings of each bitcoin holder, with proof of belonging to a specific person.

The wave of arrests of criminals who accepted payments in bitcoins is proof of this. It is worth noting that law enforcement agencies mainly focus on transactions for fairly large amounts. Even if the user does not commit illegal actions, no one can guarantee that the transactions made will not seem strange to the special services.

How to use a bitcoin mixer​

When connecting to a Bitcoin mixer, it is recommended to use a connection through proxy servers. Some services have a built-in connection via Tor. Next, you should go to the official website of the selected service and go through the easy registration of new users.

Each service offers individual methods of interaction, but in most cases it is necessary to deposit funds into your account in your personal account, mix and withdraw anonymous coins using your preferred method. The Bitcoin wallet address generated within the system is often only available for 24 hours. Some services have minimum transactions and additional terms of cooperation.

An important point in using Bitcoin mixers is a letter of guarantee indicating the wallet address and a special code, which is issued by the service when participating in mixing. The letter should be downloaded or copied. When withdrawing funds, the service requires you to indicate it as proof. If the letter is lost, the funds will also be irretrievably lost.

The speed of the services depends on the amount of the transfer and the number of confirmations required. To complicate tracking, users may also be offered deferred transactions.

To increase confidentiality, in addition to intra-service mixing, other techniques can be used:
  • Withdraw funds from the service after a long period of time.
  • Split the deposit into several parts.
  • Divide the withdrawal into several separate parts with withdrawal to different wallets.

MONERO - classic method​

The cryptocurrency Monero (XMR) will help us. It is a brother of Bitcoin, except that the XMR blockchain is completely closed. Neither the source of the money, nor the recipient, nor the amount of the payment are visible. There is simply a transaction ID with the date of its appearance, the number of confirmations, and that is where the main available information ends.

All addresses are used and generated in the network of this currency exclusively for one time, and the address that will be indicated in your wallet is only an “instruction” for creating one-time ones. It is for this reason that Monero is used by many Western darknet marketplaces along with Bitcoin, and on the largest White House Market at the moment it is the main coin.

Create a Monero wallet​

The first step to getting pure XMR from dirty BTC is to download the official wallet from the link: . After downloading and installing, you will have a choice of using it: download the entire Monero blockchain, which is the safest option, or connect through someone else's remote node, exposing yourself to the risk of IP tracking. So less time or increased security - it's up to you.

After registration and receiving a seed phrase, the entire functionality of the wallet will open up to you. You can create new addresses (it is recommended to use one address only once), send and receive XMR. I will immediately note several advantages of this crypto. Firstly, compared to Bitcoin, transaction fees are extremely small. Secondly, everything arrives quickly enough and the money arrives in your account after receiving 10 confirmations. About 20-30 minutes.

BTC cleaning scheme:​

You exchange BTC for XMR (address in your wallet). You can do this through the exchanger found on bestchange.com, but you need to be careful with this option. The exchangers listed on this site can lock BTC from Hydra. Before creating a deal, carefully read the Terms of use of the selected exchanger and make sure that there is no mention of blocking dirty funds.

The second option for exchanging BTC for XMR is to use the Western darknet marketplace search engine Kilos. For obvious reasons, this site does not process or track transactions at all. The minimum exchange threshold is quite low. However, the course is not the most profitable.

Another important problem is that Kilos uses a type of address that is not supported by Hydra. So you will have to transfer from Hydra to an intermediate link (for example, Electrum) and only then transfer to the exchanger. Link to Kilos (via TOR): http://dnmugu4755642434.onion (tab Kilos Finance - Swap)

Once you receive Monero in your wallet, you have two options. The first is to immediately exchange XMR for rubles or other currency, generally receiving clean funds. However, in theory, this action will not provide maximum security, since the first exchanger will store data about the address to which the money was sent, and the second - data about the same address, only as a source of funds. If this data is in a common database, or if during the work of bottlemen separate databases are combined, then there is a chance that the source of money and the final recipient will be connected. This chance is 1 in 11, since a transaction on the Monero network, when created, is signed by the sending address and 10 more addresses from the network in order to increase anonymity.

The second option we will use is to create an additional transaction already in the Monero network and final exchange of money from a new address. In the case of one transaction within the network, the chance of detection decreases from 1/11 to 1/121, since the new transfer will be signed by 11 more keys, each of which has 11 others, only 1 of which is your original one. Further increasing the number of transactions will also significantly increase your security.

The transfer can be made to a new account or address opened in your wallet. For greater security, you should create a new wallet directly, linked to a different seed phrase, but in order to simplify the whole process (and considering that you are not crime lords), you can make a transfer within the same wallet.

Having made one or more transfers within the network, you can confidently go to bestchange.com and sell XMR in any convenient currency. Having completed this step, you receive clean money. Congratulations!

The whole process takes no more than an hour, but the time depends heavily on the fees you set for transfers. Compared to using mixers, it is a bit longer and more difficult, but the time and effort spent are fully compensated by the purity of the funds. And in addition to purity, you also save a significant amount of money.

More profitable than mixers? Calculations.​

~$185 was sent to Kilos, after one transfer via the Monero network and an exchange on the most profitable exchanger with Bestchange they became ~$162. The final costs were 12% excluding the Bitcoin network commission. Considering that the Kilos rate is not the smallest, using other exchangers becomes more profitable than using mixers. So, having run $134 through a regular exchanger in the first step, at the exit I received $124, that is, the commission was only about 7%, which is much more profitable than using the same BitMix.
