If you are on the internet, like the EUROPOL said;

"You are not anonymous."

I wouldn't be surprised if chipmixer suddenly leaves the business too. Come to think of, bitmixer.io used to be the biggest mixer and they left the business just like that, without a reason, at least not shared with the public.

They want to leave before they get raided by the armed mercenaries of the government.

Makes sense, life is too short to spend in a jail cell.
