Ethereum is a huge ecosystem, so the Ethereum blockchain can be used in many types of activity, I see a lot of potential in the ETH coin and I can say with confidence that it will be a very good investment!
I agree with your thoughts, because I am also sure that Ethereum is the best choice for investment in the long and short term and of course when you invest in Ethereum, then you don't need to be afraid when Ethereum price down, because I'm sure Ethereum price is definitely will increase again (you only need to hold Ethereum that you have) and of course it will give you profit.
