if you bought 1 mill coins at a fixed price.... weather 0.20$ bellow or above market value... the price would definitely go up after the order is filled.
that's about 400,000BTC. supply goes down, demand is the same = price goes up
LOL, yeah it's just that simple. How do you even know your $1MM order will be filled? It could take months.
my guess:
at 3$ ... it will take hours to fill
at 2.5 you'll get about 50,000 btc a day
at 2$ you'll never get 1 damn coin.
