This article seems quite biased. Could they be a front for China? They left out one part of an article they sourced:

In September, the U.S. Securities and Exchange Commission fined three media companies, affiliated with Guo, $539 million on charges of illegally selling stock and digital assets to investors.

If he was in a position where a substantial amount of his assets were in those companies, maybe he couldn't get them out before that happened. So after the fines and then having to settle up with the investors, it may have wiped him out.

I'm curious if the huge fine was politically motivated due to his involvement in right-wing politics or his rhetoric against the COVID-19 jabs.
