so go ahead and build your little farm
Just because you can profit currently does not mean you will ever ROI. The whole point is to have enough profit margin to overcome risk (ie price drops/difficulty rise). Currently thats nearly impossible with current levels of ZEC/ETH unless you paying around 5 cents/kw TOTAL bill cost. With BTC/LTC mining your a bit better off since those markets are a LOT more stable.
they keep saying that but what i see is that the altcoin scene was always profitable since 2013, the only big downtime for peopl with expensive electricity was end 2014, and a bit 2015, but aside form that it was always profitable for everyone
with gpu rig you have virtually no risk, if everything go wrong very fast after your investment you just sell your gpu again for 80% retail or more, if everything go wrong after a year or more, you have already reached roi....so you are safe either way
in any case the big resale value will save your ass
It depends on the electricity price. If you pay 0.25 dollar per kWh, then it is not profitble for most coins.
Yeah your right. You should first how much you will earn of profit by the end of the month because if you are a negative then its not nice to mine that coin because it is not profitable in yours. Just find exact coin to mine that you will earn profit and it can pay your bills by the end of the month
For the ZEC mining, it is negative for the old cards.
