There's around 30% of the global bond market that's private and free. Composed of all kinds of private sector entities, hedge funds, some banks, families, individuals, etc, etc.
If these guys get out of bonds because of the inflationary pressure (i.e burning money in a QE environment), and also if there's a stagflation and the equity market doesn't work so well (which is possible), there could be a bond demonetization process. And in that process people could realize that Bitcoin is a secure asset/investment.
Basically a worldwide orange pilling event.
