How much approximately does each of the crypto mining rigs you sell cost to run per day?

This varies depending on the speed (hashrate), electricity provider/tariff and GPUs being used. For example, a 500 MH rig with 4 x 3090s would use around 1.8Kw whereas a 500 MH rig with 11 x A2000s would use around 737w. There are lots of different factors to consider though and would be worth a conversation if you are interested in buying a rig. A general rule of thumb right now is to expect 1/3 of mining income to be spent on electricity in the UK.

Which rig is the most common one?

The 500 MH rig is the most common as it’s a good starting point. Most customers buy one to start with and then buy more or upgrade to the 1000 MH rig or purchase more once they are confident.

Other than Ethereum what other cryptos are they capable of mining?

Essentially, any cryptocurrency that can be mined by GPUs e.g. Firo (Zcoin) Cortext (CTXC) Ethereum Classic (ETC) Ravencoin (RVN) Ergo (ERG) Bitcoin Gold (BTG)

Do you have any specification sheets for each rig with more detail than the website?

Not really as it depends on the rig in question. Also, the actual GPUs will depend on the stock/availability/price at the time of order. There is a huge shortage of these parts which is driving up prices and limiting availability. If you are interested in a specific rig, I can put a spec/quote together for you.

What will happen when Ethereum 2.0 is released?

You will keep your earned ETH but will need to switch to another cryptocurrency like those mentioned in point 3 above. You can always mine another coin but then convert your earnings back to ETH, BTC or any other cryptocurrency you like if you wish. Our personal mining setup mines ETH but I diversify the earnings across a range of around 15 cryptocurrencies that I really like to help spread the risk and reward.
