5000 dollar is a large amount and I do not think the bitcoin can reach this amount in a relative short time.
Most likely the bitcoin will rise to a pretty nice number this year but 5k is just too much and I can consider it right now as unrealistic.
This obviously will be very difficult to reach $5000, in fact I think it will never happen. you can see, even to reach $1k again it takes a very long time.
$1k can be achievable at the end of the year and if price goes higher at the time of halving then we can expect it will be much higher by the end of the year 2016.
