If Ethereum is a utility platform and the value of its coin rises, how can it continue to be used as a utility when its used as a store of value?
Most people that buy Ethereum aren't using it, they're trading.
You can try to create an asset use ethereum, There are some people are using ethereum to playing the dapps game in the platform. So, have you ever seen the bitcoin will be used or offer the utility usage to the token holders? Crypto is about a speculation and then i think that it looks very similar.
