Both Ethereum and Ripple now seem to be the most prominent among other altcoins as they have both taken to spotlight. These two coins have long been struggling to take the second position in terms of market cap. 2018 has really been an interesting year between eth and xrp. XRP took the position of second place in January, before eth took over again. The same happened just yesterday. I am just trying to imagine what would happen in the next one year, if ethereum wll be able to maintain its position in terms of market cap.
I'm pessimistic that ethereum can defend it. because even though ripple hasn't been able to, but there are still many altcoins that have the potential to take second place. like EOS, Stellar, or bitcoincash. so I think ethereum will sooner or later lose its position.
