Yes, everyone recommended Ethereum. But I have a question, I am confused why the coin that existed before ETH could lose the price. Like one example Litecoin, why Litecoin can lose the price with other new coins .. I think that coin is pretty good and it's one of the best coin. I also make it as one of my favorite coins back then. I think Litecoin will jumped, but it turned out to be defeated by Ethereum. There is also a saying about the development of technology and protocol on Ethereum by some developers that they said could surpass the price of Bitcoin someday. It's hard to imagine, but we'll see.

I think every altcoin price will increase with time. But I suggest to invest in Bitcoin for now. However, if you want to invest in altcoin, you can try Ethereum because that is the only one I think it's best.
