It was in Miami, at the North American Bitcoin Conference in late January 2014, that I first got wind, as a Wall Street Journal reporter, that people were having problems withdrawing funds from Mt. Gox, the most important bitcoin exchange at that time. A few weeks later, Mt. Gox collapsed and the price of bitcoin, which had increased fivefold in the weeks before the conference, plunged all the way to $200, where it stayed for some time. The prior price rally had turned the NABC into a raucous, celebratory affair, albeit with far less of the world’s attention on participants than is now applied to the crypto community. I wonder what the mood will be like at our twin competing conferences this time?
