I created a topic about ETH mining profitable 2 months ago. Its about my own experience, with the current market situation ( as of October 5th )
I did not done any calculation in the past few weeks, but my miners income are still covering my electricity bills and generating a few extra dollars a months
So read this topic :
Why its still worth mining ETH ( or other coins) for me
Mining ETH is ok for me ..
I got back already that money what i invested...
If you have to buy hardware now , well... thats a different story ...
