Ripple is powered by Banker 's money and it is centralised - they are trying to bump the price by putting money in it, that is not how Bitcoin reached this success that we see today. Yes they might lifted the price with self funding, but don't expect prices will go really up ;)
What is the estimated price by your opinion? I personally believe that it has the possibility to reach over 10 $ in this year, but again that is just something i personally think. I read that some banks have started testing Ripple as some sort of secure payment system, and if they switch to it, it will possibly go a lot higher than 10$, but on the other hand, if don't it could easily hit bottom....
