From a January 2nd price of $13.16, the price of a Bitcoin in USD had risen to $46 on March 16th - right before the Cyprus 'solution' was announced. Since then, in two short weeks, the price of a Bitcoin has more than doubled, reaching $101 today. This 'exuberance' in non-fiat currency, should perhaps warrant caution as we noted here [3], the US is now not only actively monitoring but has commenced regulating the Bitcoin market and those who participate should be well aware that when uncle Sam is involved, things tend to have an unhappy ending for pretty much everyone involved.
