The fact that Ripple is less 'wild', and particularly it's accessibility once up and running smoothly, have the potential to make it the one that captures the imagination of the wider population. It's launch at a time of greater publicity generally won't do any harm either. I'm backing it as the one that will really hit the big-time (although may not do much exciting value-wise). I'd anticipate positive impacts on BTC too as an indirect effect.

If you don't like your Ripples, please allow me the honour of putting them to good use for you: rfvAc84GHGybgwkWRXvN13Rt4uWNBvf73C
