About Us

We are a team of crypto-mining enthusiasts looking to share our knowledge and products throughout the world. Like many others we were frustrated with the poor quality of products and customer service. Our goal is to bring an end to that by providing you with the best products and service possible.

Contact us anytime, as miners ourselves we value honesty and being available to our customers.

We guarantee same day shipping from our warehouses in USA unlike our competitors that take 2-4 weeks to ship from Asia. However, some products will be shipped from China. 

Most importantly, we will beat anyone's prices.  



Q: Why does my Raspberry Pi say Enter Run Level?:
A: When the Raspberry Pi says enter run level you are running the default version of NOOBS (the Pi OS), this means that you do not have the ZoomHash image on your SD Card, follow the instructions here to fix the problem:
Q: I have my Pi up and running, how do I check each miner connected to it?
A: You can use the commands: "sudo screen -ls" without quotes, this will list all the screens (workers) that are currently running on your Pi, once you have the screen number (the numbers that pop up when you type that command), you will need to type in: "sudo screen -r xxxx" the x's being the number or name that is outputted by -ls.
Q: Why is my Gridseed Blade only running at half of the speed that is advertised?
A: Make sure that you setup the Pi to run with both boards, that is, every Blade you have counts as 2 ASICs because there are two boards on it. So you might have only put 1 when you meant to put 2 in the ./
Q: Do you support Windows or Mac for the Gridseeds?
A: At this time the only device that we support with the Gridseeds is the Raspberry Pi with our software. If you wish to use Windows you can follow the guide on your website, but we can not be held responsible for any damages this may cause your computer or your ASICs, and we cannot further support you in this endeavour. This guide is for people that do not wish to use the Raspberry Pi but have no idea where to start, it is located here:
Q: How much is shipping to my Country?
A: If you select the items that you wish to purchase and go through the checkout process you will get to a page that has shipping calculated, and at this point you can still back out of the order as nothing has been ordered.
Q: Where is my order and how do I track it?
A: We will e-mail you your tracking number shortly after your purchase, if you have ordered a product that is shipped out of China it may take up to 2 business days to receive your tracking information.
Q: Do you do Will Call, or In-Store Pickup?
A: Unfortunately we do not offer this service at this time.
Q: How do I return or replace my product?
A: Please read over our return policies and follow the guide on how to replace your defective unit:
