Big/medium banks are never going to use Ripple, theyre only trying it out and will drop it then make their own technology (not de-centralized!)
Blockchain will change how we send money, but not through banks. Theyre completely against de-centralized control of financial system. We need blockchain solutions like Kora (

Personally, i dont like and i wont prefer ripple to others. Because ripple is not like other cryptocurrencies. ripple is the lowest price and it is backed by the banking system. I hope ripple will be die in future and we should not encourage such kind of coins.
