Let's first see if we reach 500 usd. If we do, then we can talk about 1k or up. For me 2k is a no go..
Even if halving bring good news for us we cannot expect that high price in the month of Jan as its really too high to expect an unrealistic too.
Only the mass adoption will increase the price. The halving will not increase the price if there is no demand.
It will have a long term impact on the price while the block halving will most likely have a very short term impact on the price because the demand last year wasn't very high as the price kept fairly stable.
That the price kept itself hovering within a certain range was solely due to the block halving that is coming towards us.
People expect the price to go up so they are not really interested in selling their coins.
I am quite sure that if there wasn't a block halving this year that the price would go slowly down.
