What manipulator?
It's early September, time when, in the North Hemisphere, people buy books, clothes and all school paraphernalia, an easy "many hundreds to thousands USD, EUR, CAD(...)" expense.
As there're no Bitcoin market to this kind of stuff, yet, people will rush to cash them out causing a low. Nothing out of the extraordinary actually or unexpected. Next week this settles and btc will move up again.
How many parents do you think there are in here?
I am! I have two children to prepare for school!
I'm sure there are PLENTY! Clothes alone are a few hundred bux! Supplies add another $40 per child!
Hell, some people here ARE students that may need school supplies, even if for college!
