Cryptocurrency currencies take the concept of money, and they take it native into computers, where everything is settled with computers and doesn't require external institutions or trusted third parties to validate things.

The ledger, the distributed database - it's called a Blockchain - is held in the cloud by all the parties involved. It can't be broken by any of them. It's cryptographically too strong. You would have to compromise the entire network to take over Bitcoin.

ICOs are obviously a new and interesting form of funding for blockchain-based protocols, but it's not clear that all of them comply with U.S. securities laws or that all of them are companies that have good native use cases for new coins.

A block chain is a series of blocks. Each block is a series of computations done by computers all over the world using serious cryptography in a way that's very hard to undo.

I think almost everything about humans and human civilization is explained better by evolution than anything else.

Be present. Be meditative. Form real friendships. Stay away from business networking events or friendships where there is always an underlying business angle.
