I feel like that December is a good estimate on when bitcoin hits this price.
Although there is negative energy about bitcoin right now, the price is still sticking around between $1000-$1100. Once the decision made regarding the hard fork i think it is way easier for bitcoin to climb in value.
$1500 is a short term goal though.
In the long term, when fiat collapses, bitcoin will rise in value to more than $1 million even, as a result of hyperinflation.
Bitcoin is an asset that will hold your value, much like gold.
