For example Elon Musk is worth around $400 billion atm. With some rough calculations based on his projected growth and net worth he makes roughly $500-$1000 per second.
Which means if he dropped a few hundred dollar bills on the floor it would cost him more to bend over and pick up the money than to just keep walking.
Thats some real gangsta shit right there.
$6 million to $25 million
Would probably be enough
