The value is tied to scarcity. There are a finite number of bitcoins that can be mined. In that way, in that way, it’s more like gold than fiat currency which is even more wonky.
Bitcoin could bust but I’m betting that some form of open source / public-ledger / crypto-currency is here to stay. It actually makes a lot of sense if the cryptography is sound.
I love saying fiat. It’s like a karate move. Fiat! Fiat!
