ETH is a very solid base project and is founder of smart contract feature.ETH brought revolution in crypto and IT technology.Many ICO are using ETH channels to distribute their tokens.Today many projects are using ETH smart contract feature.ETH community is strong.ETH is fully matured.EHT price is continuosly increasing.Investment in ETH and holding it is highly profitable.
ADA is another very strong project working on improved smart contract and decentralised app (DApps) in a scalable and cheap way.Flaws found in ETH smart contract will be improved in ADA project.ADA would be matured in coming 2-3 years.So investment in ADA and holding it for 2-3 years would bring huge profit.ADA is currently undervalued.
As a conclusion both are outclass coins one is old and mature whilst other is new but have very strong idea.Currently ETH is superior to ADA.
Yes you are correct and if you are a smart investor you should pick ADA over ETH because of it’s future projects and good platform, and the price of ADA for now is highly affordable and cheaper than ETH. As a back up investment you should put some ETH in your wallet for you to have both coins on your portfolio. You can make 70-30 investment but put more capital on ADa.
