I've been researching altcoins and keep coming across some staggering figures. I think it's just too early to do math, but if I were to farm novacoins for example calculator here and I have pretty much no cost (0 power and 0 hardware), my rig can run 500-600 Mhash/s (aka 500,000-600,000khash/s since that's what the calc uses), lets ignore difficulty increase. The calculator says I can make ~$100 PER DAY. This can't be right, can someone figure out what I'm doing wrong here?

  • Well it sort of is related but with the difficulty right now it's not logical. Im mostly trying to figure out if I flubbed my math, am crazy, or should quit my day job. Commented Sep 5, 2014 at 14:07

    NVC uses Scrypt as it's hashing algorithm, like LTC. If that 500-600 MH/s figure is for Bitcoin, your speed will be significantly lower for NVC.

  • I edited it for you. I should note that my hardware is still rated for about 500 Mh/s according to the litecoin wiki. Commented Sep 5, 2014 at 14:20

    There is nothing in the Litecoin wiki list litecoin.info/mining_hardware_comparison that does 500 Mhash/sec. The entries in that table are in Khash/sec and the largest entry is 1500. I bet your machine actually does 500 Khash/sec meaning you will earn about 10 cents per day. Commented Sep 5, 2014 at 15:00

If you already have the hardware and do not pay for your power consumption, then it follows that you would always have 100% profit. If you pay for your own power consumption, you need to be aware that performing mining calculations all day will significantly increase your computer's power usage in comparison to being idle.

I haven't checked the validity of the calculator, but you can calculate your potential mining yield from your mining power and the current difficulty.

Check out this answer on How much Bitcoin will I mine right now with hardware X? for a formula.

Then, it depends on whether it is actually possible to sell the coins that you gained (whether there is a market for it), and whether the above information is acurate, otherwise, it might well be possible to make a good amount of money mining altcoins.

  • I'm just finding it hard to believe that I can make $100 per day with my 270x. I'm at work and forgot to set up teamviewer this morning, but I'll try my hand at mining altcoins tomorrow/later tonight. Commented Sep 5, 2014 at 14:09
