I don't make many promises, but one promise I regularly make to clients is that I will not be calling the top or bottom of markets with accuracy. Every rule has an exception and I seem to have fluked calling the peak of the Bitcoin bubble with timing that can only be described as exquisite. I blogged in early December last year as the price rise turned parabolic about my fears for this market. This warning turned out to be within a couple of weeks of the top of the Bitcoin market. The price is currently trading around $5,500, a fall of 70% from the peak.
