Bitcoin is the very opposite of anonymous. Permanently recorded for posterity would be a better description. The best you can get is pseudonymous, and that's if you never actually spend any of the coin.
"The traditional banking model achieves a level of privacy by limiting access to information to the parties involved and the trusted third party. The necessity to announce all transactions publicly precludes this method, but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous. The public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone."
That Bitcoin wasn't private was clear since day 0.
