But for now we cannot see major merchants that has adopted bitcoins yet because they are hesitant due to the unstable price, at this early stage it is only the investors and traders game that we can witness and for me that is good for us early adopters if we are saving bitcoins for the future.
It's not with unstable price why merchants don't adopted bitcoin as payment method since overall 1btc is equal to 1btc. Bitcoin price is matter in some cases but on the other hand, they will do transactions in bitcoin only.
It's just that demands here are not priority by them since they care for most people that uses regularly the other payment option.
The unstable market price of bitcoin seems the barricade for merchants to accept bitcoin as their payment processor because they dont really want to lose money if the price fall down and for today bitcoins market is not really known by all people thats why we cannot really see store accepts it.
