₿MIX (BMIX)

Bmix.io Overview

₿MIX is a Bitcoin mixing service that replaces a user’s submitted BTC with coins sourced from third-party cryptocurrency exchanges. Unlike CoinJoin-based mixers, the service does not pool user funds together — it sources output coins from independent exchange investors (Binance, OKX, Coinbase, and Bybit are named on the site as example sources). Users send BTC to a generated address, and receive different BTC from exchange sources at one or two specified output addresses. The service is accessible via clearnet and Tor, offers a Telegram bot, and provides a PGP-signed guarantee letter for each transaction. No registration is required. A free test option is available for 0.001 BTC.

Key Features
Exchange-Based Coin Replacement

User’s BTC is replaced with coins sourced from crypto exchange investors. The service states it does not return the same coins and performs a cleanliness check on output coins before delivery.
Two Output Addresses

An optional second output address can be specified. Coins arrive at both addresses in a random proportion, described as a countermeasure against cluster analysis.
Randomized Return Delay

The return time is set randomly within the 1–6 hour window, stated as a measure to reduce the risk of temporal transaction analysis.
Free Test

A 0.001 BTC free test is listed on the homepage.
Tor Version

A Tor version of the service is available. The Tor version operates without JavaScript; the fee calculator and transaction detector are disabled on the Tor version. Third-party services (e.g. Zendesk, Disqus) are excluded from the Tor version.
Telegram Integration

A Telegram bot (@bMixIoBot) is available for initiating transactions. A separate support account (@bMixIoSupport) is listed for customer service.
PGP Guarantee Letter

Each transaction generates a PGP-signed guarantee letter. The letter confirms the generated sending address and the terms of the transaction. It is the only accepted proof for dispute resolution. Users must save it before sending coins.
