I agree ethereum is the king of altcoin and I think ethereum will take xrp place again. Be patient, ethereum hasn't shown its fangs yet, I hope ethereum will have some good news in 2019 because in 2018 ethereum shows a very bad performance hopefully next year will be better.
Dev team have a lot of interesting projects and new features, which they plan to introduce in 2019. So now all that we can do: is wait, wait and Hodl!
