I believe it would reach 100k by the end of 2018 
Not at all.I was dam sure that bitcoin will not reach 100k $ at the end of 2018 .Bitcoin price will reach the maximum value of 25k$ at the end of 2018.This year start the price of bitcoin was 1000$ at the end the price was 13000$ sure .So if it reaches as like this year means the maximum value of bitcoin will be 25,000$.
im not so sure about that.
i have been reading all year how people are asking will bitcoin reach $1500,
will bitcoin go past $2000, will bitcoin reach $5000 in 2017?
the price cannot be predicted, it could fall after reaching $12500, it could
reach $20000 or $50000, who knows but it is going up!!
