Hi, I made some research and I 'm sure that their is a mistake but no idea where. I found on [2miners.com](http://2miners.com) that hashing rate is 6K G/s on the network I found that a rtx 1070 has a hash rate of 6 G/s or 1/1000 of the hashing power So it means that with a single RTX 1070 I could mine : 60x60x24x(1/1000) or 30 K grin A year !!! at a price of half a dollar it should mean 15K dollars a year … Where is my mistake?

> [@nagini](#): > > I found that a rtx 1070 has a hash rate of 6 G/s 1070 is a GTX, not an RTX. And it does only 0.24 Cuckatoo32 gps. There’s an RTX 2070 that does 0.37 C32 gps. You may be confused with the Cuckaroo29{,d,m,z} PoW, which Grin no longer uses. ---

Ok so I understand. Second question then, I found a miner G1 for 42G/S and 2800w at a price of 25 000. It means 0.08% (if not change) of hash rate so 25 K grin a year… without the cost of electricity … case 1 : I’m still wrong case 2 : it will be not profitable at prices of last months case 3 : price will reach break even so at least 1 or 1.2 dollars ---

This topic was also discussed here: > [@Miners profitability](https://forum.grin.mw/t/miners-profitability/8300/6): > > Quoting my own post from: The ROI would be 91 days. This is equivalent of an income of 600/91 = 6.6$ or around 19 Grin per day. The question is if the G1 Minin is available though, their website that the first batch has sold out, you have to contact the sales from iPollo: [https://www.ipollo.com/ipollo\_en/interhashMikecrm.html](https://www.ipollo.com/ipollo_en/interhashMikecrm.html) The ROI for the G1 miner is approximately 109 days, assuming there are not enough miners to increase the hash/graph rate: [https://www.coincalculators.io/coin/grin\_32?Hashrate=42&HashFactor=h&Watt=2800&ElectricityPrice=0.1&PoolFee=1&HardwareCost=25000&LH=&Difficulty=24](https://www.coincalculators.io/coin/grin_32?Hashrate=42&HashFactor=h&Watt=2800&ElectricityPrice=0.1&PoolFee=1&HardwareCost=25000&LH=&Difficulty=24) I think you should asume there are enough miners to increase the hash rate. Also it is very hard to get a G1 miner. You can also buy the G1 mini miner which has a graph rate of 1.4. The economics are the same for G1 and G1 mini, the price per graph rate is approximately the same, also the power consumption per chip is the same.
