I think Bitcoin is much more promising than Ripple. Ripple is very dependent on banks, and Bitcoin is their opposite. If the banks give up Ripple, he will die. I'm not sure that the banks are betting on Ripple.
They aren't really doing much with it. The protocol has been around for years and this year we're getting first real news that XRP might finally be used for something. Compare it to Bitcoin. People have been transaction in it 9 years ago, but who is using XRP? Ever heard of people who were doing anything with it besides trading?
This centralized bank coin will still be the same thing 5 years from now, when even less people will trust banks.
