What Is a Bitcoin Mixer

A bitcoin mixer, or cryptocurrency tumbler, is a service that mixes users’ coins before sending them to their destination. This helps obfuscate their origin, which is useful for criminals who want to avoid Uncle Sam’s watchful eye.

The US Treasury sanctioned Blender last year for helping hackers from North Korea’s Lazarus Group launder stolen crypto, but the app appears to have been relaunched as Sinbad. Researchers at Elliptic say it has already been used to launder tens of millions of dollars from hacks such as the Horizon heist.


A bitcoin mixer is a service that shuffles coins through a system to prevent hackers and other third parties from tracking your transactions. Also known as tumblers, they help you maintain digital privacy – something that Satoshi himself advocated for. These services work by combining your coins into a larger pool, then sending them to multiple recipients in an order based on the amount you send. This helps hide your original address and web identity and limits the number of transactions that can be linked to your wallet.

In the cryptocurrency world, a lot of people want to keep their financial status private. This could be because they don’t want their friends, family, or even the whole world to know how much they are making. Regardless of the reasons, they deserve to have this right. Unfortunately, many users have to choose between being anonymous and using their crypto for business or other activities.

While some may find it difficult to keep their finances private, there are ways to do so without sacrificing your cryptocurrency. One way is by using a bitcoin blender which provides a level of anonymity that is hard to achieve on the blockchain alone. Bitcoin blenders are especially useful for those who have KYCed bitcoin and need to make it untraceable again. However, they should be used with caution as these services can attract the attention of third parties and law enforcement.


Bitcoin mixers, also known as tumblers, are essential tools for preserving the anonymity of bitcoin transactions. Bitcoin mixers work by introducing additional transactions into the transaction chain, creating a complex web of addresses that makes it difficult to trace the original source. While these tools are not foolproof, they can significantly reduce the chance of your cryptocurrency being traced.

The fees for bitcoin transactions vary from a few cents to a few dollars, depending on the size of your transaction and how congested the network is at that moment. Typically, higher-value transactions require more inputs and therefore pay a higher fee. The amount of space a transaction takes up is measured in a unit called a “block” and is influenced by the number of inputs and the transaction rate (i.e. how fast the bitcoin network is at the moment).

A transaction in the blockchain is encoded as a data structure that includes a list of inputs and an output. Each input is associated with a public key, which proves ownership of the coin. Each input is also a reference to another transaction, and the combined value of all inputs is used to calculate the output. The number of outputs in a transaction can be as few as two or as many as 10 – as long as the sum is equal to the amount of bitcoin you want to send.


The fees that miners receive for adding transactions to the Bitcoin blockchain are a critical component of the cryptocurrency’s system. They support operations that keep the blockchain running, but also help prevent fraud and block spam. These fees are a sign of how free markets work in decentralized systems, and they allow the Bitcoin community to make decisions about its own system.

Transaction fees are a major pain point for some Bitcoin users, especially when sending small amounts. These fees are used to ensure that your transaction is included in the next block, and they vary according to the current rate of demand for block space. Bitcoin wallets display the fee rate (in satoshis per unit of data consumed on the blockchain, known as sats/vByte) and you must multiply it by your transaction size to calculate how much it will cost.

Using a bitcoin mixer is an effective way to reduce these fees. These services mix incoming and outgoing Bitcoin transactions, making them less visible to potential attackers. They also protect your privacy by preventing the leaking of your original address.

You can also use an online calculator to find out how much your Bitcoin will cost, based on the fee rate and transaction size. You can also compare the fees charged by different service providers. Many websites also have tools that let you compare crypto exchanges and other services.


A bitcoin mixer is an essential tool for maintaining the privacy of cryptocurrency transactions. It aims to break the link between the original transaction and its destination wallet, making it difficult for trackers to trace your funds. It works by swapping your coins with a pool of other bitcoins, so that no one can tell which coin belongs to you.

It is important to use a decentralized mixer, as centralized mixers are vulnerable to attack and have the potential to expose you to legal action. It is also a good idea to use several different wallets when mixing, as this can help reduce the risk of scamming and fraud.

The first step in using a bitcoin mixer is to send your bitcoins from your clearnet wallet to a new wallet on the blockchain. Then, you can add the new wallet to your wallet list on the clearnet. This will create a chain of transactions that makes it impossible for anyone to trace your wallet. The new wallets will have a unique address, so you can continue to use them.
