A question about RippleNet and the Ripple we buy from exchanges
I feel I have a fairly good idea how RippleNet works
How does our Ripple (XRP) that we buy on exchanges relate directly to RippleNet?
Would banks on RippleNet have to purchase XRP on the secondary market (exchanges) to "fund" transfers to other banks?
For example if Bank A using RippleNet wants to send USD 100 million to bank B (also using RippleNet) how much XRP are they using for that single transaction?
