Ethereum is still at its best, dominating the dapp market in 2018. It gains the highest active number of dapp users among others. Not just that, its leading the market also in terms of wallet holders and total number of dapps.
But despite of the stable growth, Ethereum may find 2019 a tough year to begin with. Aside from the less transaction it has compared to the others, its dapp users needs to maintain an ETH for the gass fee every transaction. This greatly affects the dapp users experience and full mass adoption of Ethereum Dapps.
This is something an Ethereum dapp must consider and/or think about this year.

Involving the cardano creator who aims to bring down the market of ethereum, but there's no doubt ethereum is performing well despite of these.
I don't think the Cardano coin has a chance against Ethereum. Let's hope that this year already Ethereum will cost more than 200-300 dollars.
I think you're wrong, a lot of altcoin is having an opportunity to fight ethereum, even promise to replace eth in the nearest time because eth are quite failing and have bad signs for a long time, the overwhelming plunge created an opportunity for altcoin to overthrow eth's position. Although it seems to have begun to recover but it is still too weak, and when looking at eth, we always feel it will be defeated at any time, so 2019 will be a great challenge for eth, it needs to confirm its position again, it does not lose to anyone else, except bitcoin
