"Jack (Smith) was sending henchmen to Eastern Europe to convey the following message to various parties (both innocent and perhaps not-so-innocent): We know that during the Yugoslavian Civil War you murdered some people, Jack is going to indict you but if you will put $X in a suitcase for me to carry back to Jack your problems go away.
$X = from $400,000 to $9 million (bribes of $7 million and $9 million were paid through Bitcoin, not suitcases).
Jack sought a $100 million bribe from a head of state who refused payment and is now in prison.
We learned of these allegations because of a passel of European whistleblowers who not only shared the stories, they wrote superbly detailed affidavits, provided texts and financial records, etc."
