If it were guaranteed that the price of bitcoin would stay the same as it is today, would you still buy it? My guess is, the answer is no. But if its value lies in being a currency, price stability is essential. And if your answer is no, how is it then not just a Ponzi scheme? In other words, everyone is buying it on the hope of someone paying more for it in the future, not to use it as a currency.
Of course you won't because you are just a speculator here thinking that bitcoin is an easy to get rich scheme and there is no doubt about it. Its good to see that bitcoin would have a stable price because finally a mass adoption could occur. Merchants and service providers won't be afraid of accepting bitcoin if this happens plus they could grow their businesses in a world wide scale because of the nature of bitcoin.
