I have never been a gambler, or traded words for indemnity. I have earned my keep by solving specific puzzles that my clients could not. The idea of arguing one's way into a paycheck is offensive to me. Studying Bitcoins is well within my demeign. I find it fascinating that the easiest way to play with them is in the form of a casino, with everyone playing the odds that they can buy low and sell high. I may have said this before. If noone is trading real work for Bitcoins, then they are simply chips in a stupid game. The house always wins. The basic principle of money markets is "screw the other guy, he's stupid." Playing that particular game at length is a clear indication that you have nothing of value yourself to offer, as is true with all gambling.
Uhmm.... securing the authenticity and accuracy of every transaction ever made on the bitcoin network is work. My GPU cycles ,which incidentally cost something, secure the network. There is no buying and selling at the mining level. It's simply performing service.
