That's not true. I don't think anyone on this forum ever really understood ripple. Yes, some banks are buying into the idea because it's a smart move. It's a direct point-to-point settlement system with no central operator, a fully decentralized network and provides transaction immutability and information redundancy just like bitcoin. It will work with any and between any currency worldwide (that includes all cryptos). It's a blockchain product just like all the others popping up.

You do realize Lightning Network isn't bitcoin, right?  It's a private network of participants that agree to use smart contract scripting language to settle debts. It only uses bitcoin for its final reconciliation. You can completely work with LN transactions (even spending from them) without ever involving the bitcoin blockchain. Well, that's just another blockchain based payment system product like ripple. It ain't bitcoin.
