The gap between the two coins is quite wide, and it will be most impossible for ripple to ever meet up with Ethereum, not now and not in the future. Ripple claims that they have real use case and that is why they are occupying the 3rd place but I see no real use case for them other than people that has been deceived of expecting their price to go to $4 holding the coin and hoping to have some great profit from the coin.
Their is a use case for them and that's being hopeful to even make it a dollar again. But no doubt XRP has the very fast transaction speed rate among others, if they will somehow upgrade I guess XRP might blow the crypto industry.
