UPDATE 2018-04-05

We are very happy to announce that we greatly reduced our fees! When we started our service the network fees had just reached an alltime high and were over 10 USD per transaction on average. Therefore we started with 1% plus 0.002 BTC per output address to cover our costs.
Since then the network fees dropped again and are quite stable now. So we decided to forward the reduced costs to our customers.

Our new fees are:
0.0001 BTC per output address + 0.5% of the mixed coins.

We hope that the network fees stay in a low range and that we can offer these low fees in the long run. However, a time might come where we have to adapt our fee structure again due to changing network fees.

UPDATE 2018-04-16

We have changed the way payouts to multiple addresses are processed. Earlier, when you chose multiple payouts, your coins were randomly distributed to the given addresses. This is easy to use and increases anonymity compared to a single output address. However it is quite unpractical if you directly want to pay someone through the mixer and send the remaining Bitcoins somewhere else. Now we allow our customers to choose a percentage of the mixed Bitcoins for each output address.


UPDATE 2018-05-14

We have added the following language options to our site:

• Spanish
• German

Bienvenido a nosotros usarios españoles!
Herzlich Willkommen liebe deutschsprachige Nutzer!


UPDATE 2018-06-20

Due to some technical issues our service could not always be reached during the past few days. Therefore we offer a ZERO FEE PROMOTION! Until the end of june we only take the transaction fee of 0.0001 btc per output address and reduce our serveice fee to 0% (usually 0.5%).
Happy mixing!

UPDATE 2018-07-14

We are announcing a new feature on our site. While we normally store records of all mixes for seven days to provide customer support, users now have the option to delete all records of their mixes before the seven days have passed. Once they have received their funds, they are free to delete all records of their transaction with the mixer.
Happy mixing!
