Right on, sir. I've rarely met anyone, not even the technically sophisticated, who can say accurately and succinctly what problem Bitcoin was designed to solve. There's really only one--the problem of exchanging money over a public network without a third-party intermediary. It's just PayPal, except there's nobody in charge who can respond to a subpoena. All of it is in service of that one narrow goal, but when it finally implodes it will take out financial futures of millions of the late-arriving schweens who are left holding the bag.
