Looks like conjoun transaction but  it is puzzled me a lot as I was sure that Mixtum doesn't use conjoin. Mixtum is a partner - mixer of Jumbler.io  or better to say the mediator between client that want to mix coins and a real mixer, which is Jumbler,  and AFAIK,  the latter dont't use conjoin and instead of this is  sending  to client coins which have been  bought from miners and/or exchanges.

Please, prove that  Jumbler uses conjoin technique in their operations.

P.S. I have used other Jumbler's partners for mixing my coins and returned transactions were never been of "conjoin" type.
