This claims that Bitcoin's market cap is 14 billion dollars, so it was either last updated in November-December 2013 during the last bull market or in December 2016-January 2017 of this bull market. Either way, it's hideously outdated and no longer represents the Bitcoin market/crypto market as a whole.
Furthermore, I'm not sure what the relevance of this actually is, because it assumes that the value of the Bitcoin market could suddenly be "withdrawn" and all of the money would be in physical cash, which is obviously impossible.
On the opposite end of the spectrum the global fiat system broke a couple of decades ago.
It's shit by nature, but it's not broken yet. That'll happen once people start paying back their debts to banks, but it could take a long time.
