FYI, never trust what random review sites say, especially if it has anything to do with Bitcoin mixers. There are quite a number of fake review sites that list scam mixers. If you are not sure of a service, always first ask here in the forum rather than risk getting scammed, I am sure members will give you good suggestions.
I would not trust any bitcoin mixer site other than chipmixer which i know because it has a good reputation of this forum.
3rd party review sites are hard to trust as they sometimes give good reviews to a bad project by taking bribe.
Its our money, so we should not deposit in any site unless we are 100% sure of its authenticity.
