Hello miners!
We are working on the model for a mining farm and would like to learn from you regarding immersion cooling for Antminer S19 Pro 110 THs/ and/or S19j Pro 100 TH/s, with Beeminer Hive setup.
Basically, our question is: "X amount of water to keep it at Y temp"
Maybe you have some experience? At least in our model, the water cost looks super high...
Any feedback is appreciated. Many thanks!
Immersion cooling is like the holy grail of mining. Very few pull it off successfully, but we all want to do it. I've had installation quotes in the low six figures to get a finished product installed in my garage. It isn't a simple thing to pull off. Maybe you mean liquid cooling, which is like using a radiator to cool, where immersion cooling is submersing your miner in liquid? In any event, if you do make an immersive mining model that uses "water" to keep it at cool temps, be sure to have a video camera recording when you flip the on switch. I'd like to see the ensuing fireworks show. I mean Beeminer Hive uses cold water that comes to the heat exchanger - https://beeminergroup.com/en/catalog/beeminer-hive-12rx/ In our location running cold water is very expensive. How did you do your setup? Especially oil cooling part? |

Hello Donny (and community), I read your very interesting post, particularly the part about your electricity rate - $0.02pp per kWh. I took a look at the tarrifs levied by DEWA ( https://www.dewa.gov.ae/en/consumer/billing/slab-tariff) which has the upper industrial rate per kWH, ie over 10001 kWh per month, set at 38 fils (10.3 us cents) and their policy seems to suggest that the more electricity you use, the more you get charged. I quote: "The current tariff intended to promote efficient consumption of electricity and water at a time it is increasingly needed, equally in the conservation and preservation of our precious resources. To know more on our conservation programs, initiatives and related conservation tips, please visit our conservation tips" I know that the Barakah nuclear plant has one of it's 4 reactors on line, but it's connected to the grid so I doubt that 'your' electricity comes from that source alone. Can you provide some clarity? Yes, the pricing you find on DEWA website is correct. However, "special entities" always secure a better electricity price depending on the license, etc. Would be happy to explain in more detail if interested, but this is more confidential information. |

Hello!
Looks very interesting, will reach out shortly!
We are normally looking at Beeminer Hive setup but are always open for new products. We even thought about the custom cooling setup for 40ft containers.
Depending on the investment size by some investors, we are also looking at warehouse construction instead of containers since they need custom infrastructure. Thanks!

Yeah in the northern hemisphere mining totally makes sense.
For UAE we have cooled shipping containers and immersion cooling. It's hot and sand everywhere, thus this is how we protect machines. And the electricity price we get is really attractive, plus we are now looking into larger mining farms that can be up to 500MW projects.

Hello, community! I was looking for a dedicated subforum for "investments in mining" to learn more about different opportunities, setup, costs, etc. More from the business and investment perspective. My questions would be the following regarding the investment structure: 1. Anyone has the experience and could share some education/business case-study on using solar for BTC mining? Is it worth considering infrastructure costs? Right now we could consider 65% nuclear, 35% solar. 2. What electricity cost do you normally have in other mining-friendly locations around the world? 3. What is the mining operation management fee you normally see in the market? 15-20% if everything is taken care of (machine purchase, setup, immersion, pools, etc.? At the moment, mining operations we have in the UAE at a very competitive electricity price of $0.0299/kWh (in a few farms we can get even cheaper), now two farms with 9.5MW and 20MW (bigger farms are upcoming soon). So far it's nuclear power, but we are also looking into a concept with "nuclear + solar" since we have around 11 hours of daylight. Also, we are open for new investors with an entry ticket of a minimum of $500k USD. We have Bitmain Antminers available immediately. Would you be interested - reach out to me by email hello@estati.ae or Telegram @Estatidxb Many thanks and greetings from Dubai! |

Hello, community!
Thought will initiate a topic for real estate investments and get your feedback.
We are currently working on facilitating crypto investments in Dubai, UAE where we accept crypto (ideally stable coins, but all other cryptos as well) and issue a so-called - manager's cheque in fiat (like an escrow account). So the buyer can pay crypto and the seller receive fiat. This also works for cars, motorcycles, houses, planes, etc.
Should we concentrate on the optimization of the manager's cheque process? Or look into tokenization perspective right away (it's not regulated yet...).
Looking forward to your feedback and comments!
Donny from Dubai!
MasterlawCoin MasterlawCoin - just checked their website, wouldn't invest a penny in them. Team members are not even on LinkedIn, profile images are stock images (just Google the images).... |

Thanks for the speedy reply!
To answer your questions:
1 - I'm more of the middle man, but also work directly with developers (no brokerage needed, have good relationships). For the secondary market (older apartments from owners) we need to use a broker that represents a seller. So investment facilitation - take care of everything with or without brokerage firm.
2 - We prefer stable coins, but if you send any other crypto, we convert into a stable coin. We then issue a manager's cheque, so we act as an "escrow account". A business in UAE has fiat currency in a bank and we issue a cheque for the value of the property and this amount is then "frozen" on the bank account. It's like a regular check you would get from someone, you bring it to the bank, bank takes it and adds money to your account.
3 - The seller can also receive crypto. It's not very common here in UAE, thus many sellers still prefer fiat currency
4 - So we have businesses in UAE and this is where the manager's cheque is issued. We normally receive 5% deposit, issue a manager's cheque and show it to the buyer as a confirmation (could be a picture, video, over a video call, etc.). Then the buyer sends the full amount and we hand over the cheque to the buyer or entitled person that will bring to the property registration office
5 - If you buy directly from the developer - you have all the information from the developer about the property including the reservation, virtual tours, exposes, etc. For secondary market (owned apartments) there's always a broker who takes care of showing the apartment before purchase, either in-person or virtually.
hope this helps!
1- "With or without a brokerage firm". Do you understand the huge difference between with and without? Let's take the "without" path because if you can have a brokerage firm to cover you (and the investors/ sellers/ buyers), then you wouldn't post here. Relationships don't keep up with business, so without contracts and agreements on paper. So in fact, you want to get the funds from both parties and run the show. And why does anyone just trusts you? Do you even know the commission that a broker wants? 2- Where will you convert them? In which exchange and under which name/ account? Why to converted in a "stable" coin and not in fiat asap? Issuing a cheque means that you own the account or you are linked with it. Because you mention regular cheque but you forget to mention that in order to get paid, the account must have the proper amount and to be clean. You will guaranty this? Because bank won't (and of course will not freeze anything). Btw, how the seller will get his money? You will give him USDT? Where will you exchange them? 3- But it's common there in UAE to receive money from an unknown and unregistered online seller who sells their properties without anything on hand? 4- Just lol! Who will verify that these doxs will be original? And under what licence you will collect personal info? In simpler words, who will "check" you out? 5- Same with 4. A virtual tour from an unknown, unregister, unlicensed wannabe guy... And the simple question is this: Why does someone uses you and not doing it by himself? After all, he will have to be there and he will know how to exchange his crypto!  P.S: Of course SFR10 is right, you still don't answer about the holding safety of cryptos but actually, we don't need to get an answer for it. The whole "project" it stinks bs... 1 - well so far we do everything with the broker, but let's say you have a friend selling a property, but you might want to get a better brokerage fee, so we can use our licensed broker partners. You cannot simply just buy a property without a broker. Cars you can buy from the seller directly. And agreements are also available. 2 - Exchanges with the company account. We normally receive crypto and issue a Manager's Cheque for our client (the buyer) that is then cleared in fiat. So seller receives fiat. 3 - this I cannot comment on, all transactions are reported in Dubai Land Department. 4 - agreements are available as well 5 - good luck exchanging crypto into a manager's cheque  I'm asking for feedback, if you have input on how to do it better, happy to learn more! |

Absolutely agree! We are also working on a few projects, primarily with real estate and we help to buy properties in Dubai (and other countries) via a Manager's Cheque, so we accept crypto and issue a cheque in local currency. We do the same for other purchases such as cars, motorcycles, boats, etc.
If any of you would need assistance - happy to help!
