It is highly unpredictable. It goes down and up couple of times. Hopefully it will rise as soon as possible since it's been sitting in low price lately. Nevertheless,  we all know that once BTC drops, the price rices double the differences from when it went down.

By the end of 2018, it will have a good price and people will continue supporting it. More people will be curious and interested to deal with BTC and how it works.
