Considering that as bitcoin grows we are observing in last days

Increasing volatility (a lot of "weak hands" are entering into Bitcoin market: those people are trend-follower that increase price spikes
Higher fees (fees are calculated in bitcoin, not in fiat value, so if bitcoin value grows fees grow too)
I believe that using bitcoin as money will continue to became harder day by day. This is creating really big problem in bitcoin network (average fee for transation is over $20) and is giving a great advantage to greak competitors (for example, Litecoin and Bitcoin Cash).

This is a small example of consequences, situation is really worsening.

So, in my opinion, in the second half of december we will not see huge rally of bitcoin. Probably, we will see a great price increase in Litecoin and Bitcoin Cash before Christmas.
In your letter to Santa Klaus, i suggest to ask for these coins!
