After a steady climb through late 2016, bitcoin sprints into the new year, rises above $1,000 yet again on January 1. On April Fools’ Day, Japan legalizes bitcoin as a method of payment, sending its value even higher. Wall Street behemoths stake a growing share of their wealth — and reputation — on the cryptocurrency market. “Ten percent of my net worth is in this space,” said Michael Novogratz at a Harvard Business School Club forum on April 19, “best investment of my life.” The former Goldman Sachs partner (and billionaire) went on to say that bitcoin will go to $2,000. Bitcoin gathers more and more momentum through May, soaring north of $3,000 by mid-June.
