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.

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.

To be a more efficient, faster, and cheaper way to send money around the world, you have to be able to get in and out of Bitcoin. You need to have a liquid exchange on either end of the corridor.

People have been scared off Bitcoin by the fact that you needed to put your money in an unregulated overseas platform that has been cut off by banks and scrutinized by the Fed. We are looking to remove the pain points and create a way to invest that is faster and more secure.

The goal for many amputees is no longer to reach a 'natural' level of ability but to exceed it, using whatever cutting-edge technology is available. As this new generation sees it, our tools are evolving faster than the human body, so why obey the limits of mere nature?

Ten Internets ago, when PayPal was started, it was all these tools that no one had built yet to bring commerce to the Internet. My first startup used PayPal.

We have to come together, worldwide, and 'think.' We have a tool - the internet - to let us do that. Let's use it wisely.

People make up rumors and put them on the Internet.
