Is there a dollar amount Trump would resign for?

As asked, half serious.

Some things to consider
– Trump has spent most of his life with the primary goal of acquiring value. He may value large sums of cash more than most.
– The job of President is about to get a lot harder, it can’t be 200 weeks of this same pace.
– Over 60 million people voted against him
– Some quick numbers: $20×60 million would be $1.2 Billion, $100 would be $6 Billion… those averages may be ambitious, but internationally there may be more people
– his estimated worth last year was ~$4 Billion
– Obviously the Presidency is worth something

Assuming there is a number that is “walking away money”, what’s the total?
