I love this stuff - bitcoin, ethereum, blockchain technology - and what the future holds.

We set up a small bitcoin and ethereum mining operation... that miraculously now is actually making a lot of money.

I'm not wed to bitcoin's blockchain. I'm blockchain-agnostic.

We need to come up with use cases for this technology that drive clear benefits for individuals and institutions - these are our customers. Too often we see bitcoin and blockchain technologies as solutions in search of a problem. We don't just need these systems to be technically better than the alternatives - we need them to be more user-friendly.

Blockchain technology isn't just a more efficient way to settle securities. It will fundamentally change market structures, and maybe even the architecture of the Internet itself.

I love Chicago.
