I don't think so that price will touch anywhere near 100K in 2018. As currently BTC is moving around 6 to 6.5K range. Volumes are also in very significant.
To reach BTC at 100K it has to multiply by almost 15 times which is very difficult at the movement.
Another thing that more then half of the year has already passed and we have only left with 5 months.
Unless there are some abnormal positive announcements or news I see it veyr difficult to 100k. But in crypto we can't say anything for sure.
