What is a Bitcoin mixer, and how does this tool work? What’s the difference between centralized and decentralized mixers, and what are the potential risks of utilizing crypto mixers?

In this guide, we’ll explain everything you need to know about Bitcoin mixers and their legality and list the main alternatives to BTC mixers.

Without further ado, let’s get to it.

What Are Bitcoin Mixers?

What is a Bitcoin tumbler? Bitcoin mixer, also known as tumbler, is a tool or a service that makes crypto transactions anonymous. As its name suggests, a crypto mixer will mix funds received from different users to hide their original source. This makes crypto transactions private and hard to trace.

Crypto tumblers are necessary since blockchains are public. This means that all transactions and wallet addresses are visible to users, and they can be linked to real-world identities. Generally speaking, these tools are not illegal. However, some countries may limit their usage.

How Does Bitcoin Mixer Work?

Now that you know what a crypto mixer is, it’s time to find out how this tool works. Once the user sends BTCs to the Bitcoin mixer’s address, the mixer will create a pool. This pool will consist of funds sent by different users. Once the pool has a sufficient number of funds, the mixing process will begin.

A cryptocurrency mixer will use algorithms to shuffle deposited funds to reduce their chances of traceability. The lack of a predictable pattern between incoming and outgoing transactions will enable anonymity.

Once the mixing process ends, the mixer will send the deposited funds back to its users. However, these funds won’t be sent to the same addresses; they will be sent to new, unrelated addresses.

Centralized vs. Decentralized Mixers

BTC mixers can be centralized or decentralized. Centralized mixers are managed by a private third party. This means that users must send their coins to wallet addresses owned by a company or individual. Centralized mixers also charge fees for their services. 

Their main advantage is the beginner-friendly design that aims to simplify the crypto mixing process. However, centralized mixers are more prone to hacking. Moreover, users may lose their funds if the company goes bankrupt or shuts down. Some mixers may also save users’ private information. Examples of centralized mixers include Yo!Mix and Mixtura.

On the other hand, decentralized mixers use open-source protocols that automate the mixing process. This means they have no central authority, which makes them more resistant to missuse. Namely, these mixers use P2P strategies to allow users to send funds without an intermediary. Instead, the funds are mixed and transferred between the users.

However, since decentralized mixers are more private, the mixing process can be very slow. Moreover, these mixers are not user-friendly. The best examples of decentralized mixers include JoinMarket and Wasabi Wallet.

Problems With Using Bitcoin Mixers

Bitcoin tumbling is essential for keeping crypto transactions anonymous. However, this process is not flawless. Namely, crypto mixers can be used for illegal activities, like money laundering and scams. Operators may act like BTC tumblers to steal funds from their users. Moreover, these mixers are often associated with ransomware attacks. Attackers can use them to hide traces of ransom payments.

Other problems include glitches and technical issues that can lead to fund loss. Finally, crypto mixers are banned in some countries. For example, a bill called the Blockchain Integrity Act was recently introduced in the US. This bill aims to prohibit crypto exchanges from accepting funds obtained through Bitcoin mixers.

Alternatives to Bitcoin Mixers

Bitcoin mixers are not the only tools that can enhance privacy. The best alternatives to crypto mixers include:

  • Privacy-focused crypto wallets — These anonymous wallets have built-in privacy features. These features generate a new address for each transaction.
  • Privacy coins — Privacy coins like Monero, Dash, and Z-cash also have built-in privacy features. For example, Monero uses stealth addresses and ring signatures. Dash uses a feature called PrivateSend, which enables sending and receiving coins anonymously. Z-cash uses zk-SNARKs to enhance privacy.
  • Lightning network — The Lightning network is a Layer-2 protocol built on top of Bitcoin. This means that transactions via the Lightning network will not be recorded on the BTC network.

Conclusion

So, what is a Bitcoin mixer? A Bitcoin mixer or a tumbler is a tool or a service that makes crypto transactions anonymous. These tools can be centralized or decentralized. The former are run by a third party, while the latter rely on P2P strategies. The main goal of crypto mixers is to provide privacy by mixing the obtained funds to hide their original source.

The main disadvantages of BTC mixers are technical errors that can lead to coin loss and their association with illegal activities, like money laundering.
