Ripple is simply eliminating a huge cost factor for banks. No more costs when exchanging different currencies, no more Swift transaction fees. Thats it. They created enough XRP so that trillions worth of value can one day be moved around the world with XRP.

XRP is also useful for micropayments and very useful for the internet of things. When your fridge orders some milk it can be done with XRP.

Starting at the top, the ripple effect can be very pervasive.
