Why do so many people describe every increase in the exchange rate as a "pump"? A pump is an artificial inflation of the price through misleading information. These small peaks in the exchange rate are merely because of supply and demand.
I don't know what you call 10 orders per second but I don't call it natural.
By definition, that's not a pump. But you'll probably continue to call ever 10% rise and fall a "pump and dump" regardless because it sounds cool.
