There are only 11 million bitcoins in existence, and there can never be more than 21 million, so it’s not a very liquid market. If a way ever emerges to break bitcoins up into even smaller fractions, that might solve the problem Bitcoins can be broken down. 1 BTC = 10^8 Satoshis. So 21 million bitcoins are actually (21x10^6)x10^8 = 21x10^14 units of currency.
