I'll reword it so it sounds better. It would take a price drop of 500 dollars  if bitcoins were worth 1k each to halve your value. Now it only takes....... 9.5 dollars. It seems like there should be more stability simply because the price is higher(and of course the price couldn't get that high without a much larger transaction volume which might smooth things out).... but  one thing I like about bitcoins is that nobody knows what they are going to do.
