The beginning of this year I made the leap to Bitcoin only and eliminated fiat from my life with Fold. I breathe easier now that I don't have to worry about how much Bitcoin to buy and when.

I think in the near distant future balance sheets will be more comprised of Bitcoin bonds than actual Bitcoin itself. In order to survive Central banks will be forced to add Bitcoin to their balance sheets in order for sovereign Treasuries to compete with private Bitcoin bonds. Game theory will be a competition between treasuries and private Bitcoin bonds. Currently everyone is short Bitcoin.
