Hardware Setup to mine GRIN

Hi there, hope everybody is fine and safe!
I am pretty sure there are already tons of posts and bits and pieces of information here and there about that topic but I was not able to find an up-to-date thread summarizing the 2-3 best hardware setup to buy/build for mining GRIN. I found things about iPollo G1/G1-mini, about GPUs, about assembling a mining computer, but I was not able to find a clear path:

  • best material to buy?
  • best places where to buy online wih trust?
  • guide to install/assembly?

Do you know if someone did recently an up-to-date article/post or check-list about that here or elsewhere that I could leverage to be equipped soon?

Thanks for the information!

Now that c32 ASICs are readily available, there’s no reason to buy GPUs for mining Grin. Buy from iPollo directly if you prefer PayPal, Nhash if you prefer USDT/Tether. Their pricing schedules are exactly the same. Nhash provides faster communication. When best pricing is considered, G1 versus G1-mini are the exact same price per hash, at least when I purchased. Go with G1 if you have 30A 220V, otherwise you’ll be dealing with a lot of Ethernet cables and PSUs during deployment. Go with G1-mini if you want significantly quieter (running within home) and more flexibility in cost and placement (only 85W each on average). G1 takes up 12.5A on a 30A circuit (limited to 24A because of 80% rule), & best price is currently $23,999 as advertised from Nhash.

I’m a fellow miner that’s GPU mined Grin since genesis and have purchased the following Grin ASICs:
G1-mini first batch from iPollo direct through this forum campaign x5
G1-mini through Nhash x20
G1 through Nhash x1
Will bundle more Grin ASICs in the future when iPollo releases their BTC & ETH ASICs.

I’ve only had 1x G1-mini DOA (foul smoke on each power-up, no hash but was accessible through admin panel) and Nhash promptly shipped a replacement in advance without additional payment or RMA. I’m awaiting RMA instructions for the DOA unit.


Hi Community,
Just a sanity check to avoid being scammed without noticing:

  • I contacted info@ipollo.com and got a quick quote and payment method as follows: > G1 mini - 899 USD/unit to be performed through USD bank transfer
  • they seem responsive and legit but according to your experience, is this the usual way to proceed and a rather safe approach?

I did read on iPollo’s telegram that they are only accepting T/T at this time. PayPal is greatly preferred by most buyers surely, but I suppose they want to avoid the 3.9% international PayPal fees + $0.20/transaction. I recommend pointing your iChicken(s) to Grinmint.


Hi there,
I got a request for KYC before they provide their bank account for wire transfer, they asked for:
ID/Passport No.:
ID/Passport name:
ID/Passport nationality:
Delivery address:
Phone number with country code:
When Identity, address and phone number are usual for purchase, did you also get a request for your passport number?

I can understand requiring your mailing address for shipping the order, but asking for your passport seems like VAT compliance for someone within the Eurozone. No, I didn’t need to provide my ID or Passport to iPollo or Nhash (I’ve ordered from both separately).

I’m currently placing an order for more G1-mini from Nhash. Finished deploying these at my commercial basement farm this weekend: https://photos.app.goo.gl/pCxYKEW22XNn9nxk6


Looks great! Thanks for sharing!
