Overview
OpenMix is a Bitcoin mixer: bitcoin mixer with Tor access, PGP-verified orders, no registration and a no-JavaScript mode: 0.5–3% fee plus $25, one or two payout addresses, order valid for 240 hours.
You send coins to a one-time deposit address and receive the same amount, minus the fee, from the service's own reserves at the address you specify, which breaks the on-chain link between sender and receiver.
Privacy & KYC
No account, email or ID is needed: the only input is the address that should receive the mixed coins.
Besides the regular website there is a Tor .onion mirror for users who prefer not to expose their IP address.
The operator states a no-logs policy and deletes order data after completion.
Fees & limits
The service fee is 0.5–3% + $25.
Orders from 0.01 BTC to 5.5 BTC are accepted.
Payouts are sent after 30 min – 3 h.
Supported coins: BTC.
Verdict
OpenMix does what a no-KYC mixer should: no signup, no identity data and a fixed, published fee.
As with any custodial mixer, test with a small amount first and keep the order details until the payout arrives.
