Its already happened, the capitalisation of Ripple far exceeds Bitcoin. However most Ripple is stored with a few of the owners and will only pay out in future for their benefit. However I choose to refer to that value in realising Ripple is likely far over valued vs its actual usage.
Little matters beyond actual usage, the prices are speculation but trade in Bitcoin done for FIAT or other goods is the largest true economy and there isnt crypto close to that. Distribution of a coin is one indication of a real market
