i think its fair to say Ripple is like the new google for Finance... the way google was in 1990's for tech industry.. and also pretty given that ripple will eat ( already eating ? ) huge percent of Swift meal ... so yeah...
I fully agree with that view. They will only need to find a way to stabilize their coins somehow, but if they hold back a significant reserve, they can play FED that way, once it is big enough. The difficulty of banks to settle internationally (where there is no common point of trust, the central bank) can indeed be solved with such an instrument, if there is going to be a way to limit volatility risk. It can be a huge inter-bank settlement layer, which is what I think Ripple wants to become. They are not embroiled in any decentralized difficulty ; ripple is willingly a centralized crypto ; this will allow them to take advantage of several aspects of crypto, without its problems due to total trustlessness, which is not needed on that level.
