We might well see $1M bitcoin for the simple face the USD could spiral downward. The US has fared well by being the world's reserve currency. It has allowed America to overspend without regard for its debt.

The challenge I see is that the new petro dollar would have to be totally de-centralized and not controlled by any one or two countries. Both Russia and Venz drilled their currencies into the ground through corruption and terrible economic policy. That is why a crypto from the US Government wouldnt be wanted either. Anything that is backed by one or two entities means they can be destroyed by those same entities.
