Simple question, difficult answer.
Many mixers are active on Bitcointalk but how long will each one last?
Seems to be just a matter of time until we'll have our next mixer shutdown.
It's a pity that the government are not seing the reason for he use of a mixer, this is only in serving for anonymity purpose and nothing more, we need our privacy, but they have taken this with the wrong approach that bitcoin mixers are being used for illegal funds transfer, if what they want is to continue in this since they cannot stop bitcoin p2p network, then the mixers are likely not to be stopped as well and the more they keep hunting after them, new ones are coming out.
Pick your one, which is next!
Don't know which, that's if there's any going soon.
