They are close to each other even before the XRP took the 2nd place spot from Eth in terms of the market cap so a big pump will help a specific crypto from their close call battle for the spot, Eth got tons of burden from ICO's lately I can tell from the projects that I've participated in the struggle to raise funds and the sudden dump from exchange when the tokens got listed, wait for the price recovery and it will reveal the true 2nd spot.
