Yes, I believe if someone sells a large quantity of BitCoins at once it can trigger a big sell-off. Certainly groups of two or three who all sell fairly large quantities of BitCoins around the same time, even just by coincidence, can trigger a panic sell-off. The more BitCoins are distributed are among more people the less a few people selling can snowball into a price collapse. BitCoin already seems to be much less volatile than it was even a few months ago. The up-and-down fluctuations are a much smaller percentage of the price. In the last few days it's been hovering around $1200, without falling below $1100 or rising above $1300. A year ago it was routine for BitCoin to lose half its price and then recover and then lose half again.
