it will go up and down in jan?
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.
Yes I agree with you especially when trading will be added in the market of each country and that could be possible if our government are all gonna adapt things and can see this big opportunities for individual, so do not worry guys this will all gonna happen if we will just continue believing on this matter.
