Well obviously this quote is not about Bitcoin.
The article is worth a read on the traceability of Bitcoin, and how the trails go dark on Monero. Note the statements quoted in the article are from blockchain analysis companies whose business model is purely TRACKING THE BITCOIN (and forks of it) BLOCKCHAIN.

PS: Those of you extracting BCC from their wallets, be careful this is a wonderful occasion for analytic companies and ultimately LE to directly link or relate Bitcoin addresses together.
PSS: Those that keep saying "Bitcoin can be used anonymously", I personally flag them as obvious LE manipulators until proven otherwise.
Careful when exchanging bitcoin for monero or monero for bitcoin through ShapeShift.io.
