I think it is possible by 2020 because many countries will accept bitcoin as another payment method for purchasing lot of things. By 2020 Bitcoin is going to build large community where it can have more value.
It may happen sooner, we are already above 6000 dollars and in 2020 we get another halving that is going to add 1000 or 2000 to the price months after the halving so as you can see we are not so far from the goal and if the lightning network is a success then more business will accept bitcoin and that will be enough to reach the goal of 10000.
