Can we expect Bitcoin and other types of coins to have good prices at the end of this year because 2018 will end. I'm starting to worry that next year will experience the same thing

I doubt on such thing because I am no longer expecting for a miracle to happen this year. The market still is on red marks and since we are already a month and half before this year end, do you think it would be enough for recovery? As such, I am expecting for the bullrun to happen next year which gives me a reason on not to sell at this moment but rather hold and wait for such thing to occur over continuous market downtrend.
