if you expect the price of bitcoin to rise to $ 20k, that might happen, it's just that we have to look at the data now, the price of bitcoin is now $ 6.305. My estimate if it does experience an increase might increase in the range of $ 7k - $ 15k in the last quarter in 2018
It is not possible that the price of bitcoin will jump again to $20k like the previous year. In my opinion the price of bitcoin will be round about 6 to 7 thousand dollars till the end of this year. There will be no big pump and dump in the price because of the investment ratio, low demand, manipulation of the market and volatility. These are the factors that do not allow bitcoin price to go up.
