Paul,
I've been searching for info on bitcoin and have been impressed with the comments/ideas expressed by Andreas Antonopoulos.  He's working on a book for O'Reilly, the outline of which is here. 

Is your offering of similar depth and scope or is it more rudimentary?  I'm particularly interested in the variables effecting anonymity as well as offline storage of bitcoins (paper wallets?).

Thank you.

First, make Bitcoin encryption a whole lot harder to break. why? Because nobody knows when the first practical quantum computer will come on line. and one of the first things they will use it for is to break Bitcoin encryption.

Did you ever have something to sell? Sell it for bitcoins or fractions of a bitcoin.

Get ready for something that is way better than Bitcoin or all those other off-shoots of Bitcoin. It will come, and it will blow even Bitcoin out of the water.

Sure, invest with Bitcoin... but also, use it.

Mt.Gox is currently around $750. This is what many people in the U.S. base its value on. Btc-e in Bulgaria is currently around $650. Got a buddy in Bulgaria who will buy a bunch that you can sell here? Sell them at BitQuick.co, at or above the current Mt.Gox rate, while your buddy sends them to you at the Btc-e rate. Split the difference.

PayPal just opened in Bulgaria. Depending on what their regs are, you might be able to send PayPal money over there for your buddy to buy bitcoins with. Of course, if you have a bank over there, and one in the States, you wouldn't need a buddy if you use PayPal.
