I mean, global economy really. Crypto has the potential and already fucked a few banks when it shit itself which could've led to awful bank runs.
If/when it destabilizes the American banking system the entire global economy will follow its lead down, at least a bit.
Like I don't think people understand how devastating letting a scam like this into proper finance can be. Finance itself already has way more latitude than it should- wait until this just splits everything wide open.
