I think BTC will go up to 15k by end of year. People will have some 'additional time' during holidays and that can impact BTC prices.
I'm not convinced, 15000$ is still hard to achieve. The price is rising very fast and it has crossed 10000% easily but that doesn't have to mean that it will continue to grow with the same speed and till end of the year we have one month left. By the end of the year some smaller price corrections are possible too, it's something not to be forgotten. Anyway I count with both possibilites, correction up to 7000$ or 8000$ again and further growth up to 11000$ by the end of December.
