An anonymous reader sends this excerpt from Entrepreneur.com: After long remaining mostly mum on Bitcoin, Microsoft's legendary co-founder Bill Gates has spoken. At the Sibos 2014 financial-services industry conference in Boston, America's richest man just threw his weight behind the controversial cryptocash. Well, at least as a low-cost payments solution. ... "Bitcoin is exciting because it shows how cheap it can be," he told Erik Schatzker during a Bloomberg TV's Smart Street show interview yesterday (video). "Bitcoin is better than currency in that you don't have to be physically in the same place and, of course, for large transactions, currency can get pretty inconvenient." ... While he seems relatively bullish on how inexpensive transacting in Bitcoin can be, Gates isn't singing the praises of its anonymity. The billionaire alluded in an oblique, somewhat rambling fashion to some of the more nefarious anonymous uses associated with Bitcoin.
