Defining 'Clean Coins': Why How a Mixer Sources Output Decides Everything
The phrase "clean coins" gets used constantly in the mixing world, often without explanation. It is worth defining precisely, because the way a mixer produces "clean" output is the difference between real privacy and cosmetic privacy.
What 'Clean' Should Mean
A clean coin, in the meaningful sense, is one with no forensic link to your prior activity. The test is simple: can an analyst trace the output back to your input? If yes, the coin is not clean — it is merely relocated. Genuine cleanliness requires that the output's history be unrelated to the deposit.
Pooling Produces Diluted, Not Clean
Pool-based mixers blend many users' coins and redistribute. The output often contains fractions of coins from the pool, which means it can inherit history — including problematic history — from other users. Taint is diluted across the pool, not removed. Analysis can sometimes still follow fractional ancestry.
Dilution is a probabilistic defense; it weakens over enough analysis.
Replacement Produces Genuinely Clean
Sourcing output from exchange markets, rather than from a user pool, means the coins you receive trace back to ordinary exchange activity — not to your deposit and not to a mixing reservoir. The link is removed at the source, not diluted after the fact.
How MixTum Approaches It
MixTum is a premium Bitcoin mixer on the Jambler.io infrastructure, operating since August 2018. Instead of pooling user funds, it exchanges incoming BTC for coins purchased from independent investors at cryptocurrency exchanges including Binance, OKEx, DigiFinex, and Cryptonex, removing the link between input and output entirely.
Output is delivered in randomized amounts across two or more transactions, with randomized delays up to six hours, defeating both volume and timing analysis. The commission is randomized between 4 and 5 percent — preventing fee-based reverse-calculation — plus a 0.0007 BTC network fee. No registration is required, no logs are stored, and every order is backed by a PGP-signed guarantee verifiable at bitlist.co/pgp. A free trial of exactly 0.001 BTC, commission waived, is available.
A Practical Example
Practical example: receive 0.3 BTC of mixed output sourced from exchange purchases — running it through a block explorer leads back to exchange activity, never to your original coins.
MixTum has operated since 2018 with a USD 50,000 escrow on AltcoinsTalks. Deposit addresses remain valid for seven days; up to two forwarding addresses are supported, with custom options for more.
