Why would you want to mix your coins?

Mixing Bitcoins (as well as other cryptocurrencies) has been gradually growing in popularity. Mixers enable you to hide your footprint across the blockchain, and you don't have to be a criminal to want to do that. There's a belief that Bitcoin is highly anonymous and thus it's impossible to track transactions in the cryptocurrency. In fact, Bitcoin is not anonymous at all, but pseudonymous, which means the following: there's a blockchain (which is a list of all transactions done in Bitcoin) and there are wallets which make transactions (send and receive Bitcoisn). If you don't connect your wallet with your personal ID, nobody knows who actually owns the wallet. There are certain situations when you MUST connect the wallet and your ID. For example, you buy some crypto via an exchange with your ID tied to the wallet or you use a personally identifiable wallet.

Thus, it's not only criminals who might want to mix their coins at a Bitcoin mixer. For instance, you want to make a purchase but you don't want to associate your personal ID with the buy. You can easily use a mixer as an intermediary, enabling you to disconnect your wallet from the purchasing transaction. Another example is storing your wealth without other people knowing exactly how many Bitcoins you have or that you have these Bitcoins in the first place.

The mixing services (aka tumblers, laundries, cleaners) are the best tools to grab back your privacy and confidentiality.

How do mixers work?

There's no rocket science behind the cryptocurrency mixers. The overall business process they perform includes the 4 Stages:

1. receive crypto from a user
2. use their own reserves to send out an output transaction to another wallet
3. store the crypto from a user in a reserve
4. use small pieces of the received crypto in order to build outgoing transactions for other users

In this way, the Bitcoin tumblers enable users to send their "dirty" coins and receive payments, made up of small portions of the Bitcoins previously received from other users. Thus, no blockchain analysis can track user's footprint across the blockchain.

What features to look for in a mixer?

When comparing various mixers, you should first look into the reputation that a website has. If it has bad reviews, it’s probably best to avoid using it since it might be a scam, i.e. they'll steal your money.

After you've found a reputable site (you'll see the list of such sites in the table below), you should consider the functions that you might need. Here are some of the most important functionalities to look for in a mixer.

Number of output addresses

Essentially, the number of receiving addresses might be the most important function which determines the quality of your mixing gig. If a mixer receives a certain amount from you, but then you break it down into, for example, payments to 10 different wallets, this will seriously impede any efforts for the blockchain analysis on your transactions.

Delays for output transactions

Another great function to have is the delay for the output transactions, in which case the mixer receives the amount from you and then sends out amounts for other mixing operations, and only after a specified period of time your transaction is processed. Thus, your outgoing transactions get mixed together with other users’ transactions, making the blockchain analysis almost impossible to do.

Minimum limits

If you need to process a lot of super-small payments, it's important to find a mixer with a sufficiently small minimum limit.


Some of the best Bitcoin tumblers charge lower fees. For instance, 0.5%. But others might charge more while also featuring more convenient functions to win from.

Mixing codes

A mixing code enables you to prevent any chance that you would receive the same coins you sent to the mixer originally.

Different grades of quality for mixing funds

In addition to these features, some of the best Bitcoin tumblers claim that they offer several different categories of mixing funds in terms of their cleanliness. They will charge you more if you want to receive absolutely clean funds and less if you just need to get the basic level of mixing quality. Though it may be very hard to verify whether this is true, we believe that some of these services might actually provide different grades of quality.

Why should I trust a Bitcoin mixer with my money?

If you have a hefty sum to mix, you should probably break it down into several smaller ones. In this way, you'll reduce the risk of losing the full amount if something goes wrong.

At the same time, the best Bitcoin mixers usually have their reputation behind them. This makes them very unwilling to steal the funds from any specific user. Instead, they may continue processing lots of transactions on a daily basis, receiving a steady stream of fees from users.

ChipMixer is probably one of the most unique Bitcoin tumblers on this list, it varies significantly from the other mixers in this list and hence its anonymity is significantly higher as well. This is the only service I know of where you get to convert your BTC holdings into chips. When you do that, you can either merge or split them which helps obfuscate your mixing efforts. There’s also some fun to be done with betting and donation functions. You can store very small-change amounts at the service in the form of vouchers, and you can withdraw to the unlimited number of addresses. You decide on the distribution percentages. The import private key function gives you the zero fees, and you get to delay the withdrawals for as long as you want. This is the most versatile and flexible mixer I’ve seen around... full review >>


BitMix is a great mixer for Bitcoin, Litecoin and Dash for those users who do lots of mixing operations on a regular basis. You can save the hashcode and avoid adjusting the settings every time you mix. The service provides you with a good degree of flexibility, enabling to set up the time delays and percentage distributions for each address. BitMix, as discussed in this review, offers only 5 addresses which might not suit every user out there, but if this is a sufficient number for you, this “Bitcoin laundry” is surely worth your attention... full review >>


CryptoMixer.io has been around since 2016, and it has won popularity and trust in the Bitcoin community. The service has an actively managed thread on the Bitcointalk forum. In this CryptoMixer.io review, we'll take a detailed walk-through through the mixer and explain how each process works. The company positions itself as the best provider for large-volume mixing transactions. At the time of analysis, the system had around 150 BTC ready to be used for cleaning your coins. The site has a minimalistic design and a pretty color scheme... full review >>


Blender.io is super-easy to use. It features a sleek and minimalist design. The biggest benefit it brings forward is the ability to flexibly adjust the fee on your transactions. This is pretty out of the beaten track since most other providers set forth a fixed fee for all your operations. The mixer enables users to break the funds across as many as output addresses and determine the delays for each address. Meanwhile, you'll lack the ability to determine the percentage distributions here through... full review >>


MixTum.io positions itself as completely different from the "classic" mixers. This tumbler sources the funds for your mixing operations from traders operating at cryptocurrency exchanges. You can't set the delays or percentage distributions here. There are only two receiving addresses enabled by the system. And the fees are randomly picked within the range from 4% up to 5%. However, the team claims that the users are much more protected and receive much more high-qualify funds in return to their dirty Bitcoins. For this MixTum.io review we tested the system and received the clean coins within 6 hours... full review >>


BitCloak reviewed here offers some of the fastest mixing procedures with only 1 confirmation required, irrespective of the actual amount you want to mix. Thus, it can be as high as 100 BTC! BitCloak seems to be the best choice on the market for those mixer users who are in a hurry. However, if you have some time to spare, you might be better off with another service since BitCloak doesn't offer that great UI/UX in terms of adjusting settings or actually seeing the fees dollar amounts. All in all, this isn't a scam as it has the company has their own Bitcointalk and Reddit threads with multiple positive reviews on them. Also, there's no information about the source of mixing funds or grade of quality for the same... full review >>

Anonymix sets the fixed 0.3% fee for all your transactions which is pretty low as compared to other providers. It's extremely fast with the deposit operations being recognized as valid after only 1 confirmation on the blockchain. Here, you can specify up 10 output addresses to effectively obfuscate your crypto’s movements within the ecosystem. In addition, users can set up delay period for each address individually. Another function you'll surely love is the ability to adjust the distribution percentages so that your output payments don't look suspicious as they might do with equal-share percentages... full review >>
