Cryptocurrencies are an emergent property of the Internet - almost a fifth protocol in the Internet suite. If Satoshi Nakomoto did not exist, it would still be necessary to invent them.

Nation states that are used to imposing capital controls will face a quandary: ban cryptocurrencies and live in the technology dustbin; enable them, and this virus - this religion, this protocol - will enable the free flow of money and language, along with packets, around the globe.

It's almost always possible to be honest and positive.

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.

I think long-term, Bitcoin is a currency of the Internet. So, even if humans don't use it, routers will use it. Web browsers will use it. Web servers will use it.

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