October 3, 2014 3 min read 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. At the event, when asked about Bitcoin’s potential to ease the cost of payment transactions for moving money from one place to another Gates waxed mostly positively about the virtual money.“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. “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.”Related: The 7 Most Fascinating Things Bill Gates Said in His Reddit ChatGates again reiterated his stance on cryptocurrencies when he delivered the event’s closing keynote address, in which he stated that, in the future, financial transactions will eventually “be digital, universal and almost free.”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.“The customers we’re talking about aren’t trying to be anonymous,” he told Schatzker. “They’re willing to be known, so Bitcoin technology is key and you can add to it or you could build a similar technology where there’s enough attribution where people feel comfortable that this is nothing to do with terrorism or any type of money laundering.”Related: Three Lessons a Serial Tech Entrepreneur Learned from Bill GatesTo see the portion of the interview in which Gates directly addresses Bitcoin, watch the video below:The last time Gates publicly commented on Bitcoin was last February, the day Bitcoin currency conversions debuted on Microsoft’s Bing search engine, when he skirted questions about Microsoft’s stance on the cryptocurrency and subsequent others during a lively Reddit Ask Me Anything (AMA) session.Instead of answering Bitcoin-related queries head on, Gates shifted the focus to the Bill and Melinda Gates Foundation-backed Vodaphone M-pesa, a mobile phone-based money transfer and microfinancing service in Kenya. Gates said that his organization is “involved in digital money, but unlike Bitcoin it would not be anonymous digital money.” He went on to predict that “digital money will catch on in India and parts of Africa and help the poorest a lot” over the next five years.Related: Billionaire Entrepreneur Mark Cuban: ‘Bitcoin Has ‘No Shot as a Long-Term Digital Currency’Now that Gates is officially Microsoft’s technical advisor, perhaps he’ll make a push for Microsoft to accept Bitcoin (or another virtual money) as a form of payment and/or weave cryptocurrency into the company’s nascent “Zero-Effort” mobile payments initiative.

We wonder what fellow billionaire Mark Cuban thinks of Bitcoin now.Related: What Do Snoop Dogg, Marc Andreessen and Peter Thiel Have in Common? Reddit, Y’all.
