Are they actively buying bitcoin, is there constant demand presently ? If you had 1000 bitcoin can you sell it all ?

What is a web site to trade bitcoins at?

When they say bitcoins have equaled about 1 Billion USD , what it is that 1 billion exactly ? The USD value of all bitcoins in circulations, or amount of trade that uses bitcoin ?

You can easily sell 1000 bitcoins near the market price without even going to multiple markets.

This shows current MtGox offer volume, bitcoinity.org/markets. 2000 coins sold instantly would drop the price less than 0.5%.

The "they" who does the buying is any person or business who wants or need coins. If no one wants them there will be no one to sell to.

The dollar amount of the last public trade times the number of coins is how the number is calculated, which is currently over $800M, but don't put too much stock in that. Obviously all coins could not be bought or sold at that price.

Gotta be safer than losing it next bank bust.

Selling 1 kBTC would yield an average price of 78.62 at the moment. The drop in price this would cause is hard to determine as the price fluctuates faster than I can type on my iPhone. The highest ask price was 78.55 at the time I ran the test order of 1000 btc., so I think the market can handle that sum easily.
