Two of these sites are not working, so I will delete them soon. Although I will probably leave UniJoin in the list only by removing the "CoinJoin" postscript (since this site has many clones, and despite the fact that it is closed, users should know which site was the original).

I have not tested Whirto (and I have no desire to test it since I sent them a number of questions and did not receive a single answer, so their hashtag will return as soon as they prove otherwise). I have not tested Mixero, but as far as I can judge, they have been working for a long time without complaints. Therefore, I need a volunteer who could show a letter of guarantee and a successful transaction, and we could take a look to determine how similar their method is to CoinJoin.
