He cares about it insofar as it’s a tool he can use and abuse to make money. Obviously he has no interest in or understanding of blockchains.

When the stock market (and confidence in the U.S.) falls, people typically flock to gold and bonds. If the U.S. is seen as unstable and at risk of not making debt payments, bonds are a bad place to move money into. That leaves gold (and to a lesser extent foreign stock markets).

With crypto though- that’s a con man’s wet dream. Volatile. No government oversight. Crypto pump and dumps are literally legal (though come close to being fraud, as people like Du Kwon have learned).
