Well, if we'll discuss about that, it has positive and negative sides. For example many traders are using bitcoin because of it's often chageable price, if bitcoin will become stable, in fact we loose such type of people, also many people has hopes that they'll buy bitcoins when it's price is cheap and than they'll wait for it's rise up. Another side is that many famouse website and business owners aren't accepting bitcoin because of it's changeable price, if it'll become stable, than they will accept bitcoin as a payment system. At least we have to lost one side of people, traders and some simple users or business owners.
I agree with the first one but I kind of doubt the second one. Just because bitcoins have a stable price, doesn't mean that they would automatically accept it. I think the primary reason why they aren't accepting bitcoins is because there's not that much people using it anyway. Everyone's using swipe cards and Paypal.
If they are going to accept bitcoins, then they would have to add another payment method on their system and then even add some more algorithms into cashing out the bitcoins into fiat form. All of these would cost money and the company owner is probably thinking that accepting bitcoins wouldn't bring as much profit as what it would cost to add it to their system. That's simply bad investment unless everyone's looking for bitcoin as payment method.
