In the nearest future no,and here is why. Banks are afraid of bitcoin and they are finding ways for people not to go for bitcoin as people will stop depositing money in banks as the interest rates are low and bitcoin on the other hand has its price increased more than 300% this year,so people will think its an easy profit for any one ,so what one of the banks did was spread this utter nonsense saying that "Bitcoin is a fraud and will blow up",people got scared and they started selling and the price went down probably because of this,if this continues to go on ,then it will be very difficult for bitcoin to overthrow fiat not only in the near future but forever.
