I was asked about creating a new currency, it is indeed possible but not easy. It starts touching on the essence of what money is. Facebook tried but didn’t get far.

This article is an interesting one where someone tried to create a new currency, got lots of momentum, and then disappeared. The woman who was the boss of the currency just vanished. Nobody knows if she was killed, ran away with the money, or what. She just vanished.

It’s also a podcast on BBC sounds.
