If mining ETH is the only profitable coin for you to mine at the moment, why would you mine something else at your own expense when you can just buy those other coins with your profits from mining ETH?
Here I would say for a cost of opportunity. choosing to win less (lose some) in the short term to gain bigger roi in medium term. As a comparison: Library Coin (LBC) has a potential of growth based on history higher than ETH - just by looking at the charts; so, wouldn't be smarter to mine LBC adn wait for the bullisgh market to return? This was my question...
Of course it wouldn't be smarter to mine LBC and wait for a bullish market to return.
What you need to do is look at my example again with DCY and swap it out with LBC. What's smarter mining LBC at 6.20 per day profit with your electric paid, or, mining ETH at 18.60 with your electric paid?
If you had a choice of buying 6.20 worth of LBC, or 18.60 with your mining power per day, which would it be?
If you want to "lose some" why are you even asking about speculating?
