mining is long term investment, the capital for mining its depend on your set up and the speed of the gadget you use, the electricity cost for mining i think not more than 20% of your daily profit.
Well, you could just use that investment to buy the coins straight from the market
. I don't see any point in mining.
Look at Aliexpress, they sell the 2014 ASIC cards for 40 bucks now, they are no longer profitable. Take that 40 bucks and buy the coins you think appreciate. Simple.
