I am using eth to trade for other coins and to pay for the transaction fee (gas) of tokens that i trade. I used to be invested in eth, but i am not interested in eth as an investment anymore. The current price is nice though.
in my opinion, ethereum is very good for investing at low prices right now so next year we will experience huge profits, still hold this coin and will get a big profit in the future.
You are right, ETH can be used as a tool for investment and profit, but also Ethereum can be used to send tokens ERC-20, for investing in projects and preserving value.
