I will mine even if coin to mine is slightly negative below electric cost. I won't like it but cheaper than paying coinbase fees and it's the best dollar cost average technique
No offense but that logic make no sense what so ever.
At the point your electric costs exceed your mining income, you are better off just buying the coin outright than paying a premium for it. Not only do you end up paying more for the coin, but you also place unneeded wear and tear on your mining rig(s).
Youve forgotten the fact that he is still mining coins and their value will usually go up over time. So he hasnt "lost" anything unless he sells for a loss... Just like the stock market.
