Purely hypothetical, but let's say either Betnomi or ChipMixer does money laundering (without the acknowledgement of their campaign participants). Are participants considered guilty, from a legislation point of view, for accepting laundered funds?
Most of the large banks in my country have been found guilty of money laundering. The banks paid a fine, management collected their bonuses, and that's it. The end.
But he's not a large bank. Banks and other large scale businesses operate under different rules to the rest of us. HSBC was caught knowingly laundering a billion dollars for the Mexican cartel and nobody went to prison. They just paid a 2 billion fine which is probably a couple of weeks profit for them and then move on. If you laundered even a few thousand you'd go to jail and pay fines. For banks it's just a calculated risk and they'll take the chance knowing that even if they get caught they'll just pay the fees and carry on.
