because it is based on the totally different principle comparing to other services. A user does not just deposit coins to mix, but creates a wallet and funds it with chips from 0.01 BTC to 8.192 BTC which a user can break down according to their wishes. After chips are included in the wallet, a wallet holder can deposit coins to process. As the chips are sent to the mixing service beforehand, next transactions are nowhere to be found and there is no opportunity to connect them with the wallet owner. There is no usual fee for transactions on this mixing service: it uses “Pay what you like” feature. It means that the fee is randomized making transactions even more incognito and the service itself more affordable. Retention period is 7 days and every user has a chance to manually clear all logs prior to this period.
