After a disastrous few days in early April, bitcoin is back over $100 and up on the month, the year and its short lifetime. ConvergEx's Nick Colas is intrigued and continues to believe that this phenomenon is the most provocative economic experiment since the invention of the euro and well worth watching. The next chapter of the story, he believes, will be the entry of a host of "Smart money" venture capitalists looking to build the currency's infrastructure. Money and currency are exactly the kind of large, scalable and complex opportunity that gets VCs very, very excited. Yes, it could all still end in tears, either by regulation or mismanagement. But bitcoin isn’t dead just yet, and it remains one of the most potentially disruptive forces in modern finance.
