Bitcoin value will upto 30k USD end of the 2018 and I think you will find the ethereum also bumped more than 1500 USD as my knowledge. Many countries already passing the bill and make the bitcoin as the legal currency. Once the bitcoin has been adopted by the various countries you will find the bitcoin value bumped like how we see when the time bitcoin adopted by Japan.
Some corporates also gonna create a new coin and blockchain technology implementation has been done.
