What is bitcoin mixing service?

The way bitcoin transactions work causes them to be chained together in a permanent public record. They are traceable along the blockchain from one bitcoin address to another. A mixing service can be used to mix one's funds with other's, with the intention of confusing the trail back to the fund's original source. Therefore, bitcoin mixing service helps protect privacy of your bitcoin transactions.

How does it work?

We have already prepared pre-mixed bitcoins for you. All you need to do is fill the form containing list of your outputs (the address where anonymized bitcoins will be sent) and send any amount of bitcoins to our bitcoin address. The mixed bitcoins will be then sent back to you automatically. You can send any number of transactions to our input address. Your bitcoins will be used in future for mixing also.

What is a "code"?

After your first exchange you will receive a special code. This code makes sure that you will never receive any of the previous coins you have added to our reserves in any subsequent transactions you make with Bitmix. In other words this ensures that you remain untraceable.

What logs are kept?

Absolutely no logs or personality identifying information are kept regarding your use of the Bitmix.Biz service. All logs are permanently removed from both our website database and from our Bitcoin wallet after your coins have been transferred out of our reserve. All forwarding entries are removed after 24 hours.

What is a Letter of Guarantee?

The Letter of Guarantee is a form of proof of our obligations.

When we provide you our Bitcoin address to which your coins should be sent to be mixed, we provide a digitally signed confirmation that this address has truly been generated by our server.

The Letter of Guarantee is the only proof of our obligations. Please always save the Letter of Guarantee before you send us coins. We completely delete your order's data in 24 hours from our database, so only the Letter of Guarantee could help to restore your order if something goes wrong with your mixing.
