I tried out the Mixerdream. The website design is pretty cool, nearly identical to what should be mixer. The interface is also fairly simple for all users, especially newcomers. They can easily obtain everything they require. My mix amount arrived on time and cannot be traced. So far, everything has gone pretty smoothly. Funds were received in less than 6 hours, which I believe should be improved. I know it's already on the website, but we'll be receiving mixed funds in 6 hours. However, I believe that time should be reduced further. Why should a user have to wait 6 hours to receive his funds? Everything else is fine to me. I hope you will consider user feedback to improve your service. I tried with min amount 0.005 BTC.
