It just depends on where you get your bitcoins from. You could:

- Mine bitcoins.

- Steal bitcoins (i.e. hack an exchange)

- Pay cash for bitcoins[1]

- Pay for bitcoins with stolen credit card info.

- Pay for bitcoins with anonymous pre-paid credit cards[2]

Of course, that just gets you a bitcoin wallet that isn't necessarily tied to you. Now you have to figure out a way to spend them without leaking personal information.

[1] The person that you pay could identify you, but if you give false information, and aren't picked up on surveillance (CCTV, etc), then it becomes a difficult to track down link.

[2] Same issue as [1]. Your weak link is the point-of-sale for the pre-paid credit card.

You missed a biggy, which is "Receive bitcoins as payment".

You could set up a bitcoin gambling website, sell some sort of SaaS for bitcoins or, perhaps the most popular and profitable route right now, sell some drugs for bitcoins. Hypothetically, depending on your state/country, you could acquire weed legally and then (illegally) send the weed through the post in exchange for bitcoins.

You would have to provide it as a Tor hidden service though, otherwise all of your expenses in running the site would open the way for your anonymity to be breached (i.e. your domain name, your hosting provider, etc).

Basically if you're providing a service to someone, then there is a possibility of said service revealing who you are. E.g. if you're sending drugs to people, then maybe the packages are traced to a source.
