A million times YES!!! ETH is one of the things that makes the blockchain industry run. The reason you even have fears is because for someone like you who seems to be a newbie in it, you probably haven't heard about those other coins in their scores, but you've heard about the streetwise ETH, that's to tell you she's somewhat safe for a new mind on this street. So, you have most security to dip into ETH and it's rival BTC. Invest in ETH.
