9 Best Bitcoin Mixer and BTC Tumbler Services – Complete Review 2021

Best Bitcoin Mixer and BTC Tumbler 2021 – The meteoric rise of Bitcoin, Ethereum, and other cryptocurrencies over the past decade has been astounding. In a world dominated by regular fiat money, BTC and crypto offer decentralization and freedom. Unlike the fiat currencies, Bitcoin is not minted by government controlled Central Banks.

The term “decentralized” in this sense means that the supply and demand are both controlled by the Crypto Community and Bitcoin Miners.

Let us first understand the normal transaction flow in Bitcoin. Here, the sender creates a transaction to transfer certain amount of BTC to the receiver. This transaction is mined by a Bitcoin Miner and is validated by other nodes within the BTC network. If you carefully observe, there is no central authority that can regulate or restrict this transaction. It is entirely community or network driven.

Why you should use a Bitcoin Mixer?

Before Bitcoin became mainstream, it was mostly used as a medium of exchange by the users of darkweb or deep web. Given the nature of crypto, people over the internet were able to send and receive funds in BTC without revealing their identity. For the most part of it, the idea was to protect one’s anonymity and ensure transaction privacy. But this is not entirely true.

Can a Bitcoin Transaction be traced?

One issue with Bitcoin is that all the transactions are stored in a Public Blockchain. It can be viewed by anyone who has access to the sender/receiver address or the transaction hash. Moreover, it’s easy to find and trace the Bitcoin money trail by following the transaction history of an address (which is publicly available on the blockchain).

Hence, at best we can call Bitcoin as being “Pseudonymous”. It means that your identity will be anonymous until the sender or receiver follows good Op-sec practices. This includes certain small measures like,

  • Using new addresses or change addresses for every new transaction
  • Not using Crypto Exchange addresses that can be linked to your personal identity
  • Using a personal Bitcoin node to interact with the blockchain

The above list is not exhaustive and you can add more security practices depending on your use-case and threat model. Whether your transactions are on the legal or illegal side is out of the scope of this article. Either ways is very much recommended to follow the above practices to ensure that your privacy is secured.

Well, then you might think that it is impossible to protect your privacy or maintain your anonymity while sending or receiving Bitcoin. That is also not entirely true. The answer lies in using Bitcoin Mixers or Tumbler services. Let’s get to them in a moment.

But considering that you strictly follow the above recommended operational security practices and use a Mixing or Tumbling service – be assured – you can 100% remain anonymous and protect your privacy!

What is Bitcoin Mixer or BTC Tumbler?

Let us first understand the concept of How Bitcoin Mixing works. Don’t get confused as this very same process can also be referred to as Bitcoin Tumbling, BTC Laundry, Washing, Mixing or Blending. Tumblers or Mixers.

These are third-party services that help in breaking the connection between the BTC sending and receiving addresses. In simple terms, they achieve this by mixing up your funds with BTC of thousands of other users who also use this service.

Bitcoin Mixing Process Flowchart

Consider the following example,

Let’s say John Doe wants to protect his identity by using a Tumbling service. John then sends over his bitcoin from address A (as low as 0.001 BTC – which depends on the minimum or maximum limits set by the service) to the BTC Tumbler. While initiating the process, John gives the service a new receiving address which is unrelated to his sending address. This service has reserves that contain Bitcoins they received from other users like our John. Now the service sends back John’s BTC (after deducting a minor fee) to his new receiving address.

For anyone who has been trailing John’s original Bitcoin address, the trail stops at the address (given by the service) to which John sent this initial funds. It is nearly impossible for them to find out John’s new receiving address. And hence, when finally the Mixing services send Bitcoin to the new receiving address – they cannot be linked to our John Doe. So, John can be assured that his anonymity and privacy are 100% secured!

How do they mix Bitcoins?

Behind the scenes, the Tumbling service breaks down the received bitcoin funds into smaller amounts and mix or scrambles them up with thousands of other transactions. For anyone following the funds in question, it becomes nearly impossible to track and trace the initial funds.

Is Bitcoin Mixing illegal?

Well, if your intention is to protect your privacy then there is nothing wrong in mixing your bitcoins. But, at the same time there are individuals who are using them for money laundering, cleaning illegal funds etc. Hence, mixers are on the wrong end of the spectrum in the eyes of authorities.

Important considerations before choosing a Bitcoin Mixing Service

While the concept of mixing your crypto and bitcoins seems exciting, we DO NOT recommend you to jump in directly. The crypto space is largely decentralized and unregulated. This opens up a lot of scope for fake exchange sites, fraudsters, hackers, and scam services.

You all might have seen those Youtube Livestreams impersonating Elon Musk promising to double your bitcoins. You see where I’m getting at. We highly recommend you “Do Your Own Research” before investing or using any crypto-related product. Ultimately, we all hate scams that prey on gullible crypto users.

So, we thought it would be a good idea to compile a list of Do’s and Don’t(s) while using a Bitcoin Mixer service online. Here is a list of things that we considered before choosing a bitcoin tumbling service.

  1. Presence, Availability and their Activity on Crypto Community forums like BitcoinTalk
  2. What is the Level of Anonymity that the Tumbling service offers?
  3. How do they deal with transaction logs? Do they save any personal data after the completion of the process
  4. What is the Fees charged for mixing BTC?
  5. Is it a Centralized or Decentralized Tumbler?
  6. How quickly do they respond to customer support queries in case of issues during the mixing process?
  7. Are they popular within the crypto community?
  8. What are the minimum and maximum limits offered for tumbling?
  9. Is the mixing or tumbling interface easy to understand and use?

Don’t be overwhelmed after reading the above list. We know that it seems like an intimidating task to check each and every service, test it by risking your funds. Hence, we went a step ahead and tested them ourselves. Based on our experiences, we have listed the top-performing BTC Mixing services below.

MixTum is unique in the sense that they implement “Bitcoin Mixer 2.0” to shuffle your Bitcoins. Generally, you find that Tumbling services mix and shuffle your BTC with funds from other users. But, MixTum operates in a different manner. They purchase clean BTC from the market or cryptocurrency exchanges. Then they use these clean Bitcoins and Tumble your original funds.

During the coin mixing process, MixTum uses advanced algorithms to perform blockchain analysis and taint analysis. You can also request them to send back your clean coins in smaller batches to different addresses for further privacy. Thus, you can be assured that you will be receiving 100% clean Bitcoin at the end of the process.

As mentioned above, MixTum charges 4% to 5% as mixing fees and accepts a minimum of 0.001 BTC and upwards for tumbling. On their website, MixTum team clearly mentions that they DO NOT maintain any kind of transaction logs. This ensures that once you finish the Tumbling of coins, your new coins cannot be traced or tracked back to your original address or to you.

Also, it is worth mentioning that you can enjoy all the benefits MixTum offers without having to create an account or register on their website. The support is available 24/7 in case you face any problems at any stage during the Bitcoin cleaning process.

3.  BitBlender

  • Network Confirmations – Minimum 3 Required
  • No Logs Policy – YES

  • Letter of Guarantee – YES

BitBlender is another notable and trustworthy service that has been offering secured Bitcoin shuffling. They maintain their own BTC reserve in the form of a chain which works similar to the LIFO algorithm (Last In – First Out). It means that the funds you send are added to the end of the chain, and you will receive clean Bitcoins from random locations of the chain. Small amounts of BTC from these random locations on-chain are clubbed together and sent to your receiving address.

This is quite innovative and you can be assured that there will not be any link between the original coins and the cleaned coins that you receive at the end of the Shuffling process.

BitBlender does not require any user registration or signup. In order to mix your coins, you only need to specify your Receiving Address at the start of the process. Then you send your coins to the address given by BitBlender. Within a few minutes, you will receive clean coins to your Receiving Address. It’s really that simple. And not to forget their strict No-Logs policy!

Another important feature you can notice on BitBlender is that you can set an optional maximum time delay of 0 hours(instant mixing) up to 7 days. This is much more Time-delay compared to other services which offer at most 3-4 hours of delay.

But, note that the time may vary from a few minutes to a few hours depending on the Time-delay set by you and Bitcoin Network congestion (transaction speed which is unrelated to our coin shuffling process).

4.  ChipMixer

  • Supported Crypto – Bitcoin
  • Minimum Deposit – 0.001 BTC
  • Transaction Fees – Highly Flexible
  • Network Confirmations – 1 to 6 Required
  • No Logs Policy – YES
  • Referral Program – NO
  • Registration Requirement – NO
  • Customer Support – Available
  • Letter of Guarantee – YES

ChipMixer in a true sense has a very unique operational process. They offer a “Chip Tumbler” concept wherein your coins are represented by Chips. You can split and merge these chips as per your requirement. In a world of automation, this is a much more hands-on approach.

With ChipMixer, you DO NOT need to give them any receiving address. Once you send them the tainted or unclean coins, you will be given an equal amount of chips. These can only be accessed by you using a special code or acknowledgment which ChipMixer provides you at the beginning of the process.

You can access your Chips using your special code and shuffle or split your coins. Then once you are satisfied, you will be able to specify the amount of chips to send to each address. ChipMixer will then forward the equivalent amount of Bitcoin to those receiving addresses.

For example, let’s say that you deposited 0.1 BTC initially. In your account (using the special code), you will be given 0.1 Chips which you can split into 10 parts of 0.01 Chips each. Then you can send 0.1 BTC to 10 addresses OR 0.2 BTC to 5 addresses. The process is entirely manual and you can split your chips upto three decimal places and forward the clean coins to multiple addresses.

Another uniqueness of this coin shuffling service is that they DO NOT charge any specific fees. It is entirely depends on the user to decide how much they want to donate to the service operators.


The above services are exceptional at what they do. But here are some other services worthy of mentioning. These are new services but have quickly earned a good name.

This coin mixing service supports multiple BTC addresses and they require only 1 Network confirmation to process your order. They do not have any referral program but they do provide the users with a Guarantee Letter for the funds.

6. SmartMix

Their support is good but not great. Overall, this is an OKAY service but there are much better options listed above.

8. AnonMix

  • Supported Crypto – Bitcoin and Ethereum
  • Minimum Deposit – 0.2 BTC
  • No Logs Policy – YES
  • Registration Requirement – NO
  • Referral Program – YES

AnonMix offers to tumble and mix both Ethereum and Bitcoin. There is no user registration required but their minimum deposit of 0.2 BTC is quite high. This might prove to be a drawback for anyone owning less BTC.

Their transaction fee hovers between 0.2% – 0.5% depending on the transaction BTC volume of the order. AnonMix DOES NOT support multiple addresses and also don’t provide any letter of guarantee.

9.  PrivCoin

  • Supported Crypto – Bitcoin, Ethereum, Bitcoin Cash BCH, Litecoin

  • Referral Program – YES

Privcoin supports mixing of multiple cryptocurrencies like BTC, ETH, BCH and LTC. They are also much flexible in terms of the service fees charged. They require a minimum deposit amount to process the mixing order.

The main drawback of this service is that they require user registration. While it may have some benefits, we do not understand how this helps in cleaning your coins. Also, PrivCoin does not give any clarity on whether they maintain user logs.


What are the Alternatives to using BTC Tumblers?

If you do not like the whole idea of Bitcoin’s pseudo-anonymity, then you might look into certain privacy-oriented cryptocurrencies. These crypto coins are built with the intention to provide transaction anonymity by default.

Monero XMR and ZCash are a few such cryptocurrencies. These have certain in-built features which prevent blockchain analysis for tracking and tracing funds. For example, Monero uses the concept of ring-signature technique and ZCash uses it’s cryptographic feature known as zk-Snark.

But, governments around the world are imposing restrictions and regulations on such privacy-coins. This makes it difficult for a normal person to transact in these crypto coins.

Closing Thoughts

In today’s modern world the Governments and authorities can track your every transaction, your bank account, your purchases both online and offline, your browsing history, your contacts etc. Although it might not be explicit, it gets quite scary knowing that your every move is being watched and tracked.

We’ve had instances like Cambridge Analytica which further threatens our privacy. Hence the need for maintaining and protecting one’s privacy is really important although you might be doing nothing wrong. Privacy is our right!

Bitcoin has become mainstream and it’s popularity seems to be only increasing by every passing day. But, it is also a notable fact that Bitcoin by default lacks privacy features and there are companies offering Blockchain Analysis services for tracking the coins.

Recourse is using Bitcoin Mixers and Tumblers which offer you privacy and help you anonymizing your coins. You might have to pay a small service fee, but that is the cost you have to accept if you want to avoid someone tracking your crypto.
