Why on earth would I or anyone want a stable price for bitcoin when we all know that the instability is where the money is, may be you don't know @op but I will like to let you know that crypto currencies are where it is today due to its volatility, just like some one else have said here, there are a lot of unstable people in this world who love instability, if bitcoins and other crypto coins where stable in price, I believe no one would take it serious cus in the world we are right now, many people are looking for legit ways of making money, and crypto happens to present this opportunity to them and us all, so personally, I don't want a stable price for bitcoin.
