I am not seeing any stability of bitcoin rather a bearish market of it. This I think is normal, last year this was also felt. Plus, we had been hearing news about the government's action against bitcoin so this factor would be affecting.
I cannot also say that 2018 price for Bitcoin would be stable considering we are at the first month of the year maybe the thread starter want to point out the consolidation of bitcoin at 10k - 11k$. since we are in bearish expect more up and down in bitcoin price and stability may far at this time.
