"The shift from the old rate of 1,507 to 15,000 is still far off the parallel market, where the pound was changing hands at around 57,000 per dollar on Tuesday."

How much is that in rubles?

The U.S. dollar has been devalued by even more (compared to when it was Real Money, when a $20 bill could be easily exchanged for a one-ounce gold coin at any bank). But that happened over the course of a century or so, not overnight.

Overnight 90% devaluation for the fiat dollar is probably coming, though. Destroying America's fiat system is necessary, but I don't look forward to it -- I expect quite a lot of pain in the short term and, for many, the long term as well.

We'll see.
