Bitcoin is one of the most viral concepts I've ever encountered.

We are very excited about the use of blockchain, whether it's Bitcoin or not, but we are as enthusiastic as ever about Bitcoin as a global currency and, really more importantly, Bitcoin as a global financial rail.

You just can't bifurcate bitcoin currency from the technology. Bitcoin will always need a monetary base.

Regulators are going to have to come up with a way to treat Bitcoin that is balanced and thoughtful but also recognize that this is a global phenomenon.

Essentially, if you decide to sell a widget using BitPay, and you sell the widget for $100, in Bitcoin you get $100. And so it doesn't matter what the price does the next minute or the next hour.

That's a term that I really like - 'permissionless innovation' - because anybody who has an idea and has a solution can tap into or can leverage the Bitcoin blockchain.
