$XRP
The gas for for transferring money using XRP, I heard it's 0.00001 XRP per transfer.
If XRP reaches $1000 per 1 XRP, that means it will only cost banks 1 cent to transfer money to other banks!
So using that kind of logical thinking, $1000 per XRP is not impossible.
It sure beats the current cost transferring money using SWIFT which is a robbery!
