$500 was the expectation for the year of 2015, but fortunately it didn't touched. This time even before the 2016 December we could reach $500 even if halving doesn't take place.
Yes that's possible, as the Bitcoin's price isn't stable till now, but i think we have to wait the halving to see the results then.
what's so special about december that you think the price will go up by that time? i really can't think of something that will happen this year in december that may push the price higher.
There is nothing special in December everyone is waiting for Bitcoin halving to be happened , Everyone is hoping when bitcoin halve (block size will be 12.5BTC ) It will give a rise to bitcoin . The price of bitcoin will increase because of halving . Also the investors are getting too much into bitcoins now .
i have no doubts about that the price will go up because of the lower block rewards, but i seriously think the block halving price increase will not be as much as some people may be hoping for. my guess is a $100 increase at most from current price level for the rest of the year.
