what does Ripple own?
XRP market cap is $30b, fully diluted is $60b; if Ripple owns the unissued XRP, then it would have $30b worth, and this would be at a ~50% discount to the XRP market price
Yes, about 25% of RippleNet volume is via XRP. Primarily remittances, but also treasury management. Xpring changed its name to RippleX and is still doing stuff.
