Let's not consider the recent price dip because we all know that it will raise again in sometime but do you think bitcoin will git the mark of $15000 by the end of March 2018?
March 2018, that's specific.
But I wouldn't go that far, i think we can reach 15k before the end of the year, or at least we'll get close to that number (i'm being very optismic, i know). After the recent surge in the price we've settled around the $9600-$10700 range, so the market's still trying to figure out that the next floor is going to be, but once the price stabilizes, I believe seeing a 3k increase in December is possible, especially when you take in consideration that at the beginning of November the price was around 7k., though the market can surprise you anytime.
But I don't think the 15k mark is going to take too long (at least not until march), I think we'll see that number soon. I think by next year, specifically the first quarter, we're going to be talking about reaching 20k, hopefully.
