How to short bitcoins

  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.
