We actually can't do that and aslo it's so useless. Firstly people holding bitcoins for price increase and buying bitcoins when price is low. Secondly price depends on fiat anyway.
Hi, thats something which is not possible. The price of a currency cannot always go up and never drops. Bitcoin price may go up sometimes and then down but the thing that can be controlled is that we dont let it drop too low. The balance between demand and supply can ensure this.
