The global monetary ledger is an SQL database at the Federal Reserve. Every other fiat currency is just an L2 on the dollar network. The L2's will collapse or survive based on the Fed's decisions. 

The real change happens when the L1 goes too far in their bailouts, and people abandon ship to a new and better L1. Like any other sinking ship, the people who panic first panic best. 

If you aren't panicking yet, today is a great day to start.
