Some of my thoughts. Start with the end result in mind - fix the money fix the world. carrots and sticks. it's no accident that carrot app rebranded to bitcoin magazine app - carrots and sticks are just short term manipulation.

Companies that forget their Why are competing against everything and that is why they lose. Did fiat forget it's why?
