When you buy bitcoins with USD or other currency on Bitfloor, it quotes you an "average price" per bitcoin and says the "actual price may vary" once the order is completed.
The "average price" stated changes periodically, but it always lags the present actual market price on Bitfloor.
Question 1: when I hit the BUY button, what price do I get? The "average price" or the current market price on Bitfloor?
Question 2: how does bitfloor calculate this "average price"?
