Unfortunately it doesn’t work like that.
I think it’s safe to say that we all expect the difficulty of crypto’s to rise and so generally you’ll get less coins in a months time than you’ll get now. You may save a few pennies in leccy now but the extra handful of coins that you could gain by cranking it to the max will likely pay for itself in a few months.
If you planning on mining and dumping immediately then fair enough. Personally, i’m holding them for a while.
It’s the same principle as the likes of coinchoose, where they tell you the most profitable coin to mine… It’s only the most profitable at that point in time. If you hold any (non-profitable) coin for a day or so you may see a spike that doubles your profitability.
