I'm most excited about all of the non-currency uses of the block chain's ledger-ordering ability. I have no idea which ones will turn out to be successful, but I'm glad all of that experimenting is happening.

Bitcoin as a globally distributed public ledger - that's the thing I'm most excited about going forward. Thinking about how to use Bitcoin in new and innovative ways. In the meantime, we have the boring uses of Bitcoin that are in the process of going mainstream.

I think the best projects understand that they don't need to invent a new currency. They don't need to use the block chain as their long-term data storage solution. And they don't need to use the peer-to-peer network as their communication mechanism. They should use the block chain as the world's most secure distributed ledger.

I'm probably the most excited about 'Turtleneck & Chain.'

I envisioned having a nice reunion, but I had no idea how great it would turn out.

When you have a good idea, the money flows.
