If you're already rich and can stomach writing a flattering letter to Dear Leader you're leaving money on the table by not committing massive fraud right now.
I feel like democrats should make it clear that if there's still a fair election and they regain power, they'll go after both the corrupt people in this admin and entities buying favors. The current state can't be too good for the society, at least there should be a clear possible downside for being a part of it.
CZ was not involved in fraud, the case only found him guilty of not doing enough to surveil his customers to sufficiently block US citizens from using a crypto exchange that other people from sanctioned countries could use.
I have no proof of this, but I would bet that there will be some quid-pro-quo involved between Trump and the pardonee. Trump does not usually give things away, he leverages his power to get more power/money.
Fraud has been an essential component of Trump's business his whole life, he clearly doesn't see it as a crime. And the crypto guys have spent a lot of money getting into his good graces. He knows a good grift when he sees it.
