Bitcoin mixers, also called tumblers, “washing” or “laundries”, are services that allow you to get rid of the history of previously conducted coin transactions. Although bitcoin is considered a confidential currency, in the process of buying or selling it, the addresses from which the currency was sent and to which the currency was transferred are saved. Additionally, many exchanges require you to verify your identity during registration. Thus, all transactions involving Bitcoin are recorded in the public register, therefore, if necessary, other interested parties can find information about the sender and the recipient of the crypto.
Bitcoin mixers work according to the following algorithm: they accept the user’s coins, split them into many parts, and mix them in random order with the coins of other users. After that, the sender’s crypto deposit is returned to the sender, minus the service commission, yet now it consists of pieces of addresses belonging to other unknown random clients unrelated to each other.
Types of Bitcoin Mixers
There are two types of BTC mixers:
- Centralized services that belong to the first generation of mixers and are already losing their popularity. The gist of their work is that the client sends cryptocurrency, pays the commission, and coins of another user are sent to the specified destination address. The level of anonymity increases as more coins holders register on this platform. The plummeting demand for this kind of service is explained by the fact that when third parties access the site’s logs, anonymity decreases significantly.
- Peer-to-peer or decentralized Bitcoin mixers allow users to directly exchange coins, while the service does not have any separate function at all. Using a protocol (CoinSwap, CoinJoin, or SharedCoin), clients can join forces and execute one general coin exchange transaction, which is completed as the required number of participants is reached. Neither senders nor recipients keep each other’s addresses, they are known only to the tumbling service.
Top 15 Bitcoin Mixers
1. UniJoin
A high-quality and reliable service that does not require registration. For tumbling, only an address for receiving crypto coins is required, that’s why it’s possible to track in the blockchain only bitcoins that were sent from the user’s wallet to the Blender.io address. How it works: the mixer has its own reserve of coins, as well as coins of other users that make up a single bitcoin chain. Upon receiving the user’s crypto coins, the service attaches them to the end of its chain. The sender receives back the coins from the beginning of the chain that are not connected to the sent money in any way. Thus, any possible connection between the coins received and sent back to the user’s wallet is excluded.
Additional benefits: the option to manually set a time delay for a transaction and to add 8 withdrawal addresses for an additional commission of 0.00008 BTC.
2. SmartMix
A popular bitcoin mixer that allows mixing even small amounts of coins. Among its advantages: an intuitive interface, no registration required, fast exchange processing with the option to set an artificial delay, up to 5 output addresses are allowed, the exchange logs are cleared after the transfer.

3. Sinbad Mixer

To increase the quality of mixing the user is provided with several opportunities to customize it. You can specify several receiving addresses and distribute the result between them. You can specify the delay for receiving the mixing result – an extra time gap between incoming and outcoming transactions from the mixer enhances anonymity. And there is an opportunity to customize service fee – it makes more difficult to establish the connection between transactions by their amounts.
4. Anonymix io
A service that also allows you to launder coins, yet you should be careful since the site has a minimum transaction amount.

The unique code you enter allows you to exclude the bitcoins you sent earlier from the process.
