I think if Amazon rumors about accepting Bitcoin as a payment method prove true, that could be a temporary catalyst to drive prices upwards to $6500-7000 in the short term, with another pullback in the days and weeks following. $10k in 2018 might be realistic, barring major regulations that are not yet announced weighing down on the price.
This was really a good development for the coin,
Once Amazon accepts bitcoin, other online shopping website will do the same and physical store will also do the same.
Bitcoin will known worldwide in no time and price will boost upward.
