With change in algorithm and rising electricity bills can mining ethereum be profitable again in the future?
How i wish you come back online now and see what is the answers about your question and to look at the market on how ethereum increases since you posted this.
Predicting the market rightly is difficult and not all investors can predict rightly but what I don't get is doubting if ethereum can sustain but luckily ethereum has proven the op wrong. I wished op invested at that time till date op would have made more profit compared to investors buying now with the problem of high transaction fee. From my opinion ethereum is totally different from other random coins and it's good for investing
