Yes, of course, why not. Ripple coins are one of the coins whose development is quite rapid and the price can rise high in a short time. If Ripple continues to grow, I believe by 2020 Ripple will reach $ 10,000.
Even if you only consider numbers, this is not possible for ripple to reach that price. Numbers are telling this, it's weird to see some people really intend to believe this kind of targets.
