It is really hard to predict the exact price range in 2018,one thing is sure that ,we wont see another rally from this price,if that happens it would be insane and the bubble will burst any time,i really did not like the price rally even now,i expected a good steady rally but this is too much of a rally and i am sure it wont sustain for a long time as the whales who purchased the coins will dump the coins down the line if they find profitable.
