Bitstamp will be forced to sell its Bitcoin due the price falling.
Let's see who will buy it

Why would they need to sell their bitcoins? They don't need to sell the bitcoins of their customers and they get cash from people buying btc which they use to pay their costs.
do you really think that a big exchanger will stay to look how the price is falling without selling his Bitcoin? It must be very stupid if he acts like that.
I mean, let's say that I have 100,000 BTC and i see the price is going down to 1 BTC = 100 USD and I know it won't recover overnight (not even in months)...what do you think that I will do ? I will SELL. Why?
You can never know what it can happen with Bitcoin. Maybe a big exchanger will be closed, maybe a big miner is closed too...the price can be down for month-years.
Also, a big exchanger cannot have too many options if he wants to sell. He must go to one of his competitors which can or cannot have a large amount of money available for a sell of 100K BTC.

100k x 230 USD = 23 MIL USD
100K BTC x 100 USD = 10 MIL
would you throw away 13 MIL USD just because you believe in Bitcoin?

These big exchangers are not fools. they care about their pockets alot(it is something normal). Who would not?
It's about business here not about Bitcoin bla bla...
