Ethereum and Ripple had this similar battle in 2017 when they both had big run ups. Now we are seeing a similar chain of events but in this time I think Ethereum is moving up based on it's future potential while Ripple I think was more pump and dump. Again we cannot predict these things and I offer no investment advice but the Ripple technology does not seem to have been advancing and evolving at the rate of Ethereum. If we take the rate of evolution of a technology as a metric and look at how quickly it is being improved on then Ethereum looks very very good.
