Eth in my opinion is a good investment. Eth seems to be the best choice right now because it is still cheap, the problem either later or in the future Ethereum is about the cost of gas. Too many deals and gas prices are getting very, very high.
Just because Gas costs slightly more doesn't mean it's a bad thing for ETH because as long as you and anyone else can still buy ETH on the exchange and trade with it, it's still very good and has no bearing on the cost issue unless you try to send it to your wallet. another.
