The Crypto-Evangelist Digital Currencies Are The Financial System Of The Future - And Here

I am a big fan of digital currencies. The idea that you can send money anywhere in the world instantly, cheaply and securely is awesome.

The problem with digital currencies is about technology - it's about building a new financial system. And that is a difficult thing to do.

There are two ways to innovate in finance: you can invent something completely new or build on existing systems and improve them. The first path - inventing something completely new - requires a huge amount of research, development, and investment, but it makes breakthroughs every few years or so. That's how we have cell phones and email, and that's how we'll soon have self-driving cars and personalized medicine.

But if you want to build something that will last for decades, you need more than just good ideas. You need people who understand enough how well the old systems worked to figure out how to improve them.
