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.

We know that the government in China has been involved in cyber attacks before. I look at our partners around the world, our traditional allies, our NATO partners who are making the same assessment. We share so much with them and rely on their technology, their expertise and interoperability in many aspects of our own armed forces.

I can imagine a future in which we give investors the opportunity to invest not just in the companies Siemens Healthineers or Siemens-Gamesa renewable energy, but also in a high-performing digital industry business.

Press and Internet freedom correlate against economic and social success, GDP, innovation, number of patents filed, and educational attainment. The more freedom there is, the more information, the more choice, and ultimately, more power for each individual.

I'd always loved technology. It's something I always messed around with in computer labs at school. So I glommed onto it very early as way to differentiate myself in business.
