The number is changing because I am slowly reducing my position in BTC given that it appears (to me) to be in a bubble. (Note: I DO think it has an inherent value and it is unquestionably an interesting technical advance. That inherent value may someday be around or above $200USD/BTC. But I believe that the current behavior is a bubble.)
