No, it's impossible. Of course bitcoin's price is very unpredictable because of its volatility, but it's already October and I don't see any reason for such increasing in prise. Not this year. And when will that happen is anybodys guess.
That price was too expensive if we're going to see it this year, because it hasn't fully recovered from falling. This October more traders expects rising trend for bitcoin, but it was just a slow movement that's going to bounce again to coup up several losses. There's no exact date for $20K to when it will be achieved, so far we're heading to that but it needs long term waits.
