Although I think there is something else behind it, something they did not tell us. it's a strange decision for me they didn't to sell the service at least
They probably earning huge profit but the people whose willing to join lately wasn't given a chance to enjoy the profit which other people having lately. Nice thing about it they really providing complete payments to those every members who joined. Eventually we have no updates yet if they're will be starting again with their mixing services, hopefully those investors will have another chances again so that profit will bebefit everybody in terms of good btc amounts.
Also the reason of closing Bitmixer was seizing of famouse tor websites because almost every bitcoin was coming from bitmixer, isn't it still clear for everyone?
Yeah, it's pretty obvious that Bitmixer closing down was related to the law enforcement takedown of Hansa, Alphabay and BTC-e. The timing is just too obvious. I have no doubt it was a cash cow. I think that mixer services are best off developing their businesses over ~2 years or so, banking profits and disappearing. Much longer than that, and you are asking for a completed investigation by law enforcement agencies. There may not be good legal precedent, but I am sure the US government would argue that tumbler services are conspiring to launder money.
