People who are earning bitcoins will be much satisfied with stable price as it will give them stable income but people who wants to make quick profits in trading will never like price stability.
I think it's a fact that those who want stable prices can turn it into btc-e codes and don't have to worry about the ups and downs, but those who are earning money with bitcoins actually want a unstable price because that's the main thing with which they earn money. I mean there are a lot of price traders.
