I would guess 5k per ETH
something very poor you have designated the future for the etherium. Many experts already today declare that in the near future we will be able to observe the real and very rapid Take-off of the etherium in price. The block chain of the etherium has many possibilities and the etherium will be even more in demand. Thus, the price can soar up to 15,000 dollars.
basically everything that states by experts is still just a prediction with the observations they do and can not guarantee will happen later. because the current movement is still very difficult to understand in the market, but I believe that growth will continue to increase the price. we can only hope that what has been stated by experts can happen later.
