I would say that 10% are "smart" investors not 25%. I came from Forex trading and there is all the same, except much more volume and less volatile. What you are writing is more for day traders who follow their assets few times a day. The holders are passive investors that invest in longterm and do not bother with price movement much.

But the principle is correct :) We need to bank on those pumps and those who want to manipulate will lose in the end.
