Whales can't pump it to 20,000 alone, they'll start the ball rolling and then let the small fish push the price up. They'll also offer support whenever theres some downward pressure on the price. But 20k won't happen overnight.
This math speculations shows that thay are able to do this. But yes they can earn more letting fomo help them by doing it slower. 1k each day and they will spend half of money to pump it in 1 day (I think that 
)
