We are on a crazy strategy with our central bank. It's good to have alternative ecosystems. It's not that the dollar will go away, but we need other options if it crashes or wildly inflates.

We know that flat and non-hierarchical systems use information best. I've tried to do that with my own company because it works better that way.
