Really have no clue regarding the target but based on history it should be between around $12
XRP is the standard, the government friendly and bankers friendly coin.
This is a personal feeling.
XRP is no more that pnd $0.2x coin
Once XRP hits the media all new money will flood into
Even catching up to Bitcoin's current market cap in such a short time span would be a miracle, exceeding it by 5X is a pipe dream.
My biggest position currently is in Ripple, so I'm a big believer in it's upside.
However, I think a more realistic (but still highly optimistic target) is $1 or $2 Ripple by March 2018. $15 is a pipe dream.
Considering the initial shoot up went from 0.006 to 0.30 while adding lets say 100 financial institutes, we can easily say that it could shoot up again to 0.40 - 0.60 by adding another 100 financial institutes. It wouldn't shoot up 4500% of the current value. Though the values could differ by another additional .20 to .40 based on the transaction volumes by these financial institutes. So the potential is around 0.60$ to 1$ approx.
However I wish you are correct & I'm wrong... after all who does not want it to be 15$ ;)
Time to change the name again :D
I might be completely wrong but my firm belief is that if a coin did something it is able to do it again.
Let's wait and see who knows
