Until the price reaches $10, the totalmarketcap would be 450 billion dollars, much more than what bitcoin has now (250B) So it means that if bitcoin needs to do another x10 to make ripple worth $10 at least.

Take year 2017, put ripple and btc prices on same graph, and you won't see
much correlation at all
