$10K at the end of the year is achievable. The month of August is about to end and a slight improvement in market prices has been observed. If it continuously runs this way, bitcoin value might even cross the $15K margin at the end of this year.
I'm on the more conservative estimate of its price; 10k$ by the end of this year. The problem with bitcoin reaching 15k$ is that newbie investors might get caught up again by the hype. If that happens, were are looking at another "December 2017"-- and that is very unhealthy if we are aiming for mass adoption.
