Lol, that's just laughable. If it was true (XRP targeting banks) then XRP wouldn't be the most heavily shilled scamcoin in existence.
XRP would have a potential use case if banks weren't corrupt as fuck and actually wanted to charge lower fees. The fact that it's a scam doesn't mean it isn't built for banks
The other problem with ripple is there are like billions of ripple locked up owned by the creators. If they start dumping all that into the market, Ripple will crash.
