A financial bubble.. Like the one caused by the inflation of the dollar to unimaginable levels? 1/2 of all dollars in existance have been printed in the last 6 years.
I would much rather have hard asset like Bitcoin, that is backed by the biggest computer network that has ever existed, that has a hard cap of 200m, than Federal Reserve IOU notes that can be printed ad-infenitem with zero recourse from you and me other than being made more poor.
