Then they will have cornered the market, but usually that doesn't work out too well for the people who attempt it.  Like the Hunt bros with silver and some other dudes in the grain market years ago. 

No. If he tried to buy so many bitcoins, the price would be skyrocketed before he would get even a small part of them. So, he would not be able to buy them in the firdt place.

To put it simply.
Suppose you want to buy 1 million bitcoins per $500 each.
You'll find just 100,000 coins at $500;
for the next 100,000 coins you'll have to pay $1000 each one;
for the next 100,000 coins you'll have to pay $2000 each one;
etc etc
and, in the extreme case you want all, all, all the bitcoins, for the last existing bitcoin you'll have to pay trillions of trillions and the whole galaxy.

Reminds me of that story:
A businessman comes to a village, where there are lots of monkeys. He promises that he will give $10 per monkey, initially people don't believe it but as time goes on, they start catching and selling nearly 50%(initial population 1k) of the monkeys to the businessman. He then tells the people that he will be going somewhere else and will come a month later with a better offer. A month later he does come back and this time offers $40 per monkey, now there are only 25% of the monkey left after villagers sell all the remaining monkeys. Once again the businessman before going to to some other village says the same thing as last time. And a month later after that comes with an offer of $160 per monkey, this time all monkeys are captured and sold by the villagers and the businessman gives the payments promptly, now no monkeys are left at all in the village. Now what the businessman does is, leaves his secretary in the village and goes somewhere else with the same promise as the other times, this time he promises that he will offer $640 per monkey next time. Now what the secretary does is, starts selling monkeys each for $400, as the villagers know they can later sell for $240 profit, and that there are no monkeys in the village that they can sell, they start buying the monkeys from the secretary. Now what happens you ask? The secretary runs away with the money and then meets the businessman who then laugh at the villagers' stupidity.
While the villagers have monkeys 

If this happens then the bitcoin price will be increased too much because there aren't much sell orders with the actual price.

bids and sells.

if you sell, price plunge
if you buy, price skyrocket.

if you want, you can sell right now 1 BTC for 10 000 USD.
and trust me, they have plenty of offer like that to wait a big (and crazy) player.

Hello. I was just thinking: what would happen if someone or a group of people such as Bill Gates, decided to purchased all the bitcoin in circulation, or a majority of it anyway.

They could purchase it for $500 per Bitcoin.
Then, due to the hightened demand and lack of any other way of getting bitcoin, they could be sold on for more than $1000. Making a $500/unit increase.
