The property of bitcoin that keeps me out of it is that I do not know what factors drive its value (if it has any). With the dollar, we know there are many drivers that affect its value such as the size of the US deficit, the level of interest rates in the US, the relative strength of the US stock market which affects the international flow of funds, and the host of economic factors on the other side of the dollar trade. So you have the size of deficits in Euro land, their stock market strength, etc.
What drives the value of the bitcoin up or down??? Is it just emotion? Count me out, unless I understand what drives it to go up and down.
