I totally agree with you. I think ETH is cryptocurrency number 2 after Bitcoin. Biggest and best after Bitcoin, and if Bitcoin mining is very difficult .. we still have ETH. The price of each cryptocurrency will always go up, but there are some cryptocurrencies whose price can be overtaken by the new crypto.
For me, it makes the world of crypto very unique, but if you ask about ETH, is ETH good or not .. then I will reply that ETH is one good Altcoin, good in terms of price, mining, protocol, and good for investment , as you already said.
