Morale of the story: Everybody should ALWAYS mix their coins and use Tor for BTC related activities. Information is power. Never give it away.
Never recommend noobs to use Tor, it's a honeypot where they are worse off than not using Tor at all.
I disagree, with a caveat: do not use Tor to access stuff linked with your real name, and always use end to end encryption to avoid eavesdropping.
