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.
I think you should widen your scope on ethereum, trading and using are the same thing as long as you trade if you are using it's fee it's private key and anything associated with it, there are already companies using Ethereum don't know where you get that idea.
