To the extent that we can be certain about anything, I think it’s certain that humans will move to a cryptographically secured digital currency that uses PoW and has a stock to flow higher than that of gold. Whether that is bitcoin or something else is to be determined. Anyone uncertain about bitcoin should be as if not more uncertain about the dollar and any other currency imo. At the end of the day everyone has to pick a horse, I think bitcoin is the fastest horse.
