there has been a while everybody knows that bitcoin isn't fully anonymous and there was many attempts to tackle this problem, so what's new in your case? have you just discovered this issue? even Monero has its own issue concerning anonymity, I think you need to tell us the truth about your decision.
It's literally in his statement, he doesn't want to help criminals make money / wash it for them.
Sad to see this site go, since it was the only trusted mixer i know, and the only one i could trust.
I feel like there's alot more going around then just your sudden change of opinion on anonimity/privacy with bitcoin.
You've probably received threats from the FBI/CIA, that you should shutdown your site, which is honestly, pretty sad.
It was a really very hard decision. Especially it was hard to drop this business because of incredible high income. But we never had any government or legal pressure, it is only my own opinion. I really believe in clean transparent Bitcoin. I really happy that Bitcoin legalized as payment system and currency in many countries, I actually didn't believe in this in 2011.
This is extremely hard to believe, sadly enough.
