"least"?
If you have 2 million dollars lying around you can commit any federal crimes and buy a pardon.
Which may seem like a lot but also consider if you're doing something like funding literally terrorism it's probably not that hard to scrounge up 2 million. You don't go to federal jail for jay-walking.
If that's not a good example then consider TrumpCoin where literally Trump meet with the largest holders of the coin (i.e. people that paid the most; at least intended too).
