If you allowed PayPal to pursue its destiny, there are moves it could make to become the largest financial company in the world.

After PayPal, I never thought I would get interested in payments again. But bitcoin is fulfilling PayPal's original vision to create 'the new world currency.'

I know when my company has closed a deal and when it hasn't.

There is some risk that if the wrong regulatory regime gets adopted in the U.S., then the center of innovation could move to other countries. If blockchains are the next Internet, that would be a very unfortunate development for the U.S.

The efficiency, credibility, and liquidity of the financial markets have been foundational to the largest economy in the world.

If somebody told me you'd be a one and a half billion dollar company and be the largest in the world, I wouldn't have believed it myself.
