How many Bitcoiners are there?

We can ask a three letter agency. They probably have an up-to-date close estimate.

This is a tough one to calc. For my part, I've had an account or two at every new service that's opened. That includes exchanges, wallet services and stores requiring registration since MyBitcoin. As an example: I currently have about 20 nontrivial wallet accounts at blockchain.info. I have more than 50 nontrivial addresses  currently and that has been as high as 110. I have 4 accounts at BTCe. My favorite for the trollbox is JesusChrist. lol  All 4 have nontrivial balances. You're going to have a hard time figuring this one out but I would guess less than a half mil worldwide.
