everyone has a different opinion. people who are still precious on bitcoin will always think positively about bitcoin. although at the beginning of the year bitcoin greatly fell but as we see bitcoin still able to survive and start to stabilize again. I am sure at the end of 2018 bitcoin prices up to the moon.
Cryptocurrency market is so unpredictable that we do not know what will be in a week or next month. At the end of the year, the price may reach new ath, but it may drop drastically. Large price fluctuations mean that no one can predict this.
