-ripple has nothing to do with the rest of the criptos, for what i understand its aimed at solving a very specific problem for banks, so it plays well with current world structures (unlike bitcoin)
-ripple is already being used by some banks, wait until a couple more add themselves to the consortium, probably during this year?
You understand it wrong. Ripple the software may in theory be of interest to banks (although it is dubious), but XRP most certainly is not. You don't need XRP to use Ripple. No one uses the currency Ripple.
Of course it can rise far anyway, as long as it is kept rising and greater fools come along. This is helped by the fact that Ripple the company controls pretty much all Ripple the currency, so they can just keep it off the market until said fools arrive. They can siphon them off in a controllled manner, and please keep in mind that you are competing with them if you plan on getting rich by selling off your tokens in time.
