The way bitcoin or any other public-blockchain transactions work causes them to be chained together in a permanent public record. They are traceable along the blockchain from one crypto 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 (or other coin) mixing service helps protect privacy of your bitcoin transactions.
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.
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 (or other coin) wallet after your coins have been transferred out of our reserve. All forwarding entries are removed after 72 hours.
If attacker knows the service fee, he can analyze blockchain to find exact sum transferred and discover your destination account.

We have already prepared pre-mixed bitcoins (or other coins) for you. All you need to do is fill the form containing list of your outputs (the address where anonymized coins will be sent) and send required amount of coins to our address. The mixed coins will be then sent back to you automatically. You can send any number of transactions to our input address. Your coins will be used in future for mixing also.
Randomize options allow you to receive more than one back transaction to your wallet from our service. Without this option while use our service you'll get one backward transaction with clear coins, but if you enabled this feature you'll receive 2 or more transactions per output address.
It makes blockchain analysis as hard as possible.
