XRP is excellent, but there's something about the coin that must be said, and isn't.
As XRP is used by banks to fast transfer money with lower costs than the current protocol SWIFT, the currency must be cheap. An expensive coin, means for a minimum fee, an expensive fee. Thus, the coin will remain relatively cheap and never going to be worth many dollars, but just a few.
That's why banks invest in XRP, because it will remain cheap for a long long time, which means, lower costs for international transfer.
Of course, banks will need liquidity within the coin, for that reason a controlled and minimal volatility is going to be inherent to the currency.
Just my humble opinion. Nice Post!
