I just want prices to be stable - at any price. It wont be useful for payments until then.
Stability is relative. What are you relating Bitcoins to?
The price of oil in USD fluctuates constantly.
The price of gold in USD fluctuates constantly.
The price of oil in gold fluctuates constantly.
The price of oil and gold in EUR fluctuates constantly.
The price of wheat in GBP fluctuates constantly.
...etc...
Hell, even the USD has fluctuated against itself over time:
What do you need stability for again? (:
