Bitcoin is a bubble that can happen at any time, and I also expect bitcoin prices to soar up to $ 50,000 in 2018, and in the future I also believe bitcoin will have a higher value.
Agree with that, we really don't know where it goes, any time there is a change which everyone isn't expecting it to happen. As we recall 2017 bitcoin's price are totally soaring high which bring to much attention to the public, but suddenly it goes down fast just like the way it goes up.
