Very possible.. We are so close to be touching $20000 right now, i really think that we are going to be between $20,000 and $21,000 before the end of the year.
21k USD.
This is just a speculation, of course, but if you look at the charts and how the market has been changing during the last few days/weeks we could realize that it will be on those rates before 2018.
There is a lot of people who are saying that it will be $25,000 or more, but i dont think that it will really happen.
