Bill Gates on Bitcoin

As an asset class, [Bitcoin's] not producing anything and so you shouldn’t expect it to go up. It’s kind of a pure ‘greater fool theory’ type of investment.....I would short it if there was an easy way to do it....

Bitcoin and ICOs, I believe completely [they’re some] of the crazier, speculative things.

Bitcoin is an exciting new technology. For our Foundation work we are doing digital currency to help the poor get banking services. We don't use bitcoin specifically for two reasons. One is that the poor shouldn't have a currency whose value goes up and down a lot compared to their local currency. Second is that if a mistake is made in who you pay then you need to be able to reverse it so anonymity wouldn't work.

Overall financial transactions will get cheaper using the work we do and Bitcoin related approaches.

Making sure that it doesn't help terrorists is a challenge for all new technology.
