Well ETH has dropped for more and XRP has gone a good market price advantage as there are good adverstisement also being made by the ripple team. This makes the way for ripple to be great and market price for ripple has a good market price fluctuations which could be enjoyable to all traders. This makes ripple market cap volume done good in its increase.
I dont think ripple is a good coin. Etherium has more chances to be the secong - largest cryptocurrency in the world, not centralized XRP.
