1. This is not an argument. 2. When you are trying to make an argument, even though it is offtopic, you still have to be factual. 3. You know who else is a billionaire? Steve Jobs. Oh, my bad, wrong example... 4. My dick is bigger than yours (factual fact) thus I must be right and you are always wrong. Note to myself: When (not if but when) I become a billionaire, if paying a whore's hush money, always do it with out of pocket CASH, so it is untraceable...
you have raised the well known concept of plausible deniability. Trump's situation does not rise up to a successful level of plausible deniability. Cash is still king.
Depends where you live. I know in Europe a few countries where you cannot pay cash more than 3,000 euro anymore to buy a car, buy gold, pay a hospital bill... Split payments in tranches of below 3,000 euro will not help as it is forbidden. if you want to deposit cash in a bank account it has to be YOUR account and if the amount is big you should even explain where the money comes from. Banks even have to report suspicious transfer above 10,000 euro... to the tax administration.
