Once an address has been doxxed, you've got a lead on any address used in a common transaction. It doesn't conclusively unmask these other addresses, so whether this counts as “really that difficult” depends on your investigative powers and your definition of “difficult”. Because of KYC[1] and AML[2], an address belonging to an exchange wallet should probably be considered doxxed. An authority can say “Hey Coinbase, I see you sent coin from address A on this date. Show me what account that came from.” CoinJoin[3] was intended to solve this problem, but apparently doesn't[6]. I was going to…

I'm a co-author of this paper. It's available here: https://arxiv.org/pdf/1708.04748.pdf The surprise here isn't that Bitcoin isn't perfectly anonymous. There are two new findings.
