Are Crypto Mining Rigs Worth It?

Cryptocurrency is a decentralized, secure, and anonymous currency that does not have a physical form or any centralized managing or regulating body. The first cryptocurrency was in 2009, known as Bitcoin, which Satoshi Nakamoto created. Since then, many other forms of cryptocurrencies have been in development. With the evolution of crypto mining using crypto mining rigs, crypto provides easy transactions, high security, a hedge against inflation, high growth, high returns, increased privacy, and portfolio diversification.  

Crypto Mining

Mining is a process used to verify crypto transactions recorded and added to the blockchain in a ledger called a block. The mining process requires many resources such as power, specialized equipment, and tech-savviness. Mining provides an essential service because it ensures that no single person can alter or falsify transaction data in a way that would corrupt the blockchain. Mining requires a certain level of expertise and access to capital investment. However, if you can get your hands on mining machines such as GPU rigs or ASICs, then you can start making money right away.  

Crypto Mining Rigs

Mining rigs are hardware and software-based systems developed to solve cryptographic hash functions thousands of times per second and earn crypto coins as a reward. The crypto mining setup must be powerful to manage this volume of work. Mining requires a lot of computing power and electricity, making a cryptocurrency mining rig very expensive. Large-scale investors usually set up crypto mining rigs because the payoff can be very lucrative. A good crypto rig can cost anywhere from $3,000 up to $10,000 depending on its functionality, efficiency, and any additional features they may offer.  

Why Invest In Crypto Mining Rigs

Crypto mining rigs are physical devices that hold the keys to a new cryptocurrency wallet. A cryptocurrency mining rig will not only help you mine for coins but also give you a chance to make your coins grow at a faster pace than if you were just investing in it. People are investing in a crypto mining setup because mining has also become profitable with the increase in popularity and value of cryptocurrencies. The cost of a crypto mining setup depends on their power, so you should choose the one based on what cryptocurrency you mine.  

Configured Rigs

You can mine cryptocurrency on personal computers, but the amount earned will be very little compared to what you make from an adequately configured cryptocurrency mining rig. Software-based crypto mining rigs allow users to create multiple mining machines using their existing computer hardware or cloud-based virtual machines. A hardware-based mining rig has a specialized piece of hardware built solely to solve cryptographic problems as quickly as possible and earn rewards in the form of cryptocurrencies.  

Invest In Crypto Rig Today

Cryptocurrencies offer great opportunities for investors who want to make big profits. If you are interested in investing in cryptocurrencies and want to earn huge profits, you should go ahead with crypto mining rigs. You need to determine what kind of returns you can expect to make on your investment, as well as how much time it will take for your investment to pay off. However, a cryptocurrency mining rig is quite convenient because it does not occupy much space and still gives you sufficient investment returns. You can either use a crypto mining rig yourself or rent it out to other miners.

Cryptocurrency: How Does Crypto Mining Work?

Cryptocurrency mining is a process where a new digital coin is created and entered into circulation and validated by a blockchain network and distributed ledger. Cryptocurrency is a digital decentralized asset based on blockchain technology and can be used as a form of payment digitally.

Introduction Into Cryptocurrency Coin Mining

Mining cryptocurrency requires a computer built specifically for mining or a GPU mining computer. In addition, all mining rigs using GPUs should always be connected to a stable and reliable internet connection. Each crypto miner is required to be a participant in a group of an online crypto mining pool.

Ways Of Mining Cryptocurrencies

CPU Mining

Cryptocurrencies can be mined in various ways, each one requires a different amount of time. Previously, CPU mining was the preferred option for most miners, although most people discovered it to be too slow and outdated. It takes months to make little profit, compared to the high electricity it consumes.

GPU mining

GPU mining is a cryptocurrency mining method that maximizes power consumption by bringing a set of GPUs together in one mining rig. A cooling system and motherboard are needed for the rig.

Application-Specific Integrated Circuit

Unlike CPU and GPU, the ASIC miner is specifically built for mining cryptocurrencies, they mine more cryptocurrency in little space of time than the GPUs. However, it is expensive to acquire.

Mining by Playing Games

This method of mining is done by playing crypto idle miner games. You can find a lot of these games that mine different types of cryptocurrencies

Pools of mining

This type of mining allows miners to put their computer resources together to give them the added advantage of mining in chunks on a blockchain. At the successful end of the mining pool, the profit is shared across the miners in proportion to the number of computer resources each of the miners was required to contribute towards the pool.

Proof of Signature or Work

Coin mining is almost the same as mining precious stones or metal. Miners of the natural gems will unearth diamond, silver, or gold, Crypto or Coin miner always work towards the introduction of a new cryptocurrency into circulation. In order for a miner to get rewarded with crypto, he or she needs to set up machines to solve difficult mathematical tasks in the form of cryptographic hashes. A hash is an abbreviated digital signature for a bunch of data. They are generated to protect data transfer on a blockchain network. Miners are always competing with fellow miners to zero in on hash value created by a cryptocurrency transaction, the first miner to break the code and earn the right to add a block to the ledger and get rewarded. Every block works with a hash signature to show the identification of the previous block, creating an unbroken chain of blocks that refers back to the previous block. That is why peers on the blockchain can simply verify whether a particular block is correct or valid. And the crypto miner validates the block and solves the hash properly to earn the reward.

Is Mining Cryptocurrency A Good Investment?

The onset of Bitcoin (BTC) as a trillion-dollar asset class has attracted interest. As much as the cryptocurrency business is thriving, it is essential to understand that Bitcoin mining as a process can turn out to be very expensive. You should first invest in computer hardware like a crypto miner, gpu mining, or crypto idle miner equipment and software. Do not forget that you need the power to keep your crypto equipment like computers running. All in all, the most important topic to examine is its profitability, especially with the most current time. The trend of the profitability of cryptocurrency since its inception and its performance in 2022 will bring out the best projection of its future profitability. Since 2015, the interest in cryptocurrency has surged. The value of bitcoin has also risen since 2015, from close to $300 a coin to a maximum value of close to $20,000 a coin by December 2017. It later underwent a small fluctuation by reducing its value from $20,000 per coin at the end of 2017 to approximately $8,000 a coin in November 2019. From the lows of $8000, its value climbed to about $67,000 in October 2021. Other cryptocurrencies have also experienced extreme highs and lows in value.

What affects Cryptocurrency profitability?

Cryptocurrency mining is quite a simple process. It would require that you just put up a computer to solve a complex math puzzle and get a coin reward or its fraction. The initial bitcoin miners earned coins quite easily and quickly by just utilizing the computing power of crypto miner, GPU mining equipment in their homes. With time, the calculations have grown to be more complicated. With the current age, crypto mining is only possible with advanced Application Specific Integrated Circuit machines only used to mine Bitcoin. However, hardware like the crypto miner, GPU mining for mining bitcoin continues to advance quickly, rendering the older ones obsolete. Therefore, a miner must continually purchase computer hardware in its updated state, which is quite expensive. You might decide to mine Bitcoin on your own. Before you commence, you will need to be conversant with the following factors which will affect your profitability; - The cost of electricity - The cost of equipment - Time that will be needed for a recoup of the costs of equipment - The fluctuations of the value of cryptocurrencies impacting profitability - The frequency of the need to purchase new and more powerful machines

Will Crypto be profitable in 2022?

If you want to mine in 2022, you must understand a few things first. The time is taken to mine a whole bitcoin depends on the amount of hashing power from the contribution of a miner. If you contribute more hashing power, a block will be solved faster. That will lead you to reap the block reward in minted bitcoins that are new. The developers of Ethereum are working hard to upgrade the Ethereum network to a better one called “Ethereum 2.0”. This will change Ethereum’s consensus mechanism to proof-of-work from proof-of-stake. That will mean that it will no longer be possible to mine Ethereum with a network that uses proof-of-stake. Thus only the people holding large amounts of Ethereum will have the ability to stake their tokens while becoming validators. Therefore, new entrants might find it very difficult to invest in Ethereum since the time that you would profit from Ethereum by yourself has been replaced by mining pools.

Global Warming Potential
décembre 06, 2021

What is GWP – Global Warming Potential

The concept of global warming has trumpeted a lot globally, especially with climate change enthusiasts. Reducing the effects of global warming needs a collective effort of earth's dwellers. You can choose to participate in this noble effort, but how much is your knowledge of global warming? Hopefully, the question will trigger your interest in understanding global warming correctly. Greenhouse gases (GHG) increase the earth's warmth by slowing the escape rate of energy to space and through energy absorption. Thus, there was a need to develop the Global Warming Potential to act as a yardstick for measuring the level of harm of different gases.

What is the Basic Definition of Global Warming Potential?

The measure of different gases' relative effects of global warming best describes the GWP definition. GWP compares the amount of heat in a certain mass of a specific gas with the heat found in carbon dioxide with the same mass over a specific period. Global Warming Potential as a measure is an essential tool since it pinpoints the specific gasses speeding the rate of global warming. The larger the GWP of a particular gas, the more likely it is that that gas will cause more warmth to the earth when compared to carbon dioxide. Therefore, policymakers utilize GWP to measure opportunities to reduce emissions in different sectors and gas-producing industries. It is important to note that gwp plays an essential role in managing all the emissions reporting and accounting systems that have an association with the UNFCCC. Primarily, they are used to weigh the benefits of reducing the production and emission of a particular gas against another. For instance, the global warming potential of methane, GWP refrigerant, and other gases. A specific type of GWP has been used for a long time, called the 100-year GWP. This kind measures the effects of greenhouses gases in 100 years from emission. Recently this kind of measure has been overhauled by a 20-year GWP measure. This measure shortens the time frame of GWPs since it uses a 20-year period for measuring the global warming potential of methane, GWP refrigerant, and other gasses. The global warming potential of methane, GWP refrigerant, has been found to cause one of the highest adverse effects on the environment. Thus, an extreme early reduction in the global warming potential of methane, GWP refrigerant, could reduce the rate of warming by a percentage of 25 to 40 between the years 2030 and 20502.

Global Warming Potential a global warming tool management

Global Warming Potential serves as the best tool for the management of global warming. The short-lived emission of gases has caused a massive reduction in warming for many decades. That will create a healthy and conducive environment since, with time, the lethal gases that hasten global warming would have been tamed and managed. Policymakers will be specific with the type of gasses to regulate and their production management levels.

What Is Better Single Phase Cooling Or Two-Phase Cooling?

This is a question that many people often ask themselves. Let's begin with a common factor; both systems single-phase cooling and two-phase cooling use immersion cooling, a liquid that conducts heat better than air. They also don't require CRAs, chillers, CRAHs, or raised floors. Even with that, these two technologies have significant differences.

Below is a simple description of how the two work

Single-phase cooling

Single-Phase cooling is usually installed vertically in the coolant bath of a hydrocarbon-based dielectric fluid. Heat is transferred to the coolant through direct contact with the server components. However, unlike the two-phase cooling system, its coolant doesn't boil off. It remains in liquid form hence the term single phase and is cooled down via a heat exchanger.

Two-phase cooling

With this system, its servers are sealed in a bath specifically engineered fluorocarbon-based liquid. This liquid has a low boiling point hence it heats up easily in the server. Boiling the liquid causes a change to gas, giving the system its two-phase cooling system. To help in decision making see how these two technologies compare across four important categories;

Structure and upfront cost

Two-phase cooling systems are a bit complex in their engineering and are quite expensive to maintain and install. Pumps are not needed to circulate fluid around its servers however it employs the use of sealed racks. In contrast, although Single-phase cooling or single immersion requires a pump to circulate the coolant through the system, this operation is not as complicated as two-phase cooling. It has minimal operating expenses and functions efficiently.  

Efficiency level

Both technologies blow the doors off air-cooled data centers in their cooling efficiency. But the two-phase cooling is better as it has a PUE of 1.01 to 1.02 versus 1.02 to 1.03 for the single phase. The single-phase helps in crushing relative energy inefficiency of non-immersion cooled systems. This simply means it has a good cooling capacity and high-density performance.

Density capabilities

Two-phase cooling is often used to support high-rank densities of up to 250kw. This is in all ways impressive however getting hardware of 100kw in the market is hard. Single-phase cooling can handle 200kw per rack lower than the two phases. This is made possible when attached to a chilled water system. However, it is true to say that both technologies provide sufficient cooling power and can handle any power-intensive equipment.

Global warming potential

Both technologies help (ICT) leaders in locating their data centers, because they are easy to install as compared to the traditional air cooling systems. According to studies fluorocarbon-based fluids used in two-phase cooling present several safety liabilities such as global warming. The boiling action in this process also affects the IT assets through a process called cavitation. Single-phase cooling normally uses dielectric coolant, electrosafe that is inert, non-corrosive, not flammable and the GRC has proven single-phase immersion to be cost-effective, reliable and it does affect the environment negatively.

The bottom line

This is a simple comparison of the two immersion techniques. The single-phase cooling functions way better than the two-phase cooling system. This, however, doesn't mean that the two-phase is not good, it’s only that the single-phase is affordable, has easy operations, and has less maintenance.

What Is Immersion Cooling? Everything You Need To Know!

Immersion cooling is a heat transfer method where the hot fluid is placed in direct contact with a coolant. The most common example of this is when water is boiled and then used to cool a hot engine. Immersion cooling has been used for many years, but it's just starting to become popular in high-performance computer systems. Liquid immersion cooling works by passing the warm liquid over one or more heat exchangers connected to a radiator or a fan. Air moves through the radiator, picking up heat from the liquid, cooling as it passes through the radiator.  

Working Of Immersion Cooling

Immersion cooling takes this concept one step further by placing the liquid directly into contact with the source of heat. In other words, the CPU is submerged in a tank of liquid that transfers heat from the component into the liquid itself. As you can imagine, doing this requires some very specialized equipment, and plenty of precautionary measures must be taken to ensure that nothing goes wrong. The main benefit of an immersion cooling PC is its ability to handle high heat fluxes without requiring excessive surface area on both the cooling equipment and the computer. This results in increased performance per unit volume or unit weight, allowing computers that would otherwise overheat using conventional air-cooled techniques to be operated effectively.  

Several benefits come with an immersion cooling system, and they include:

  • Cooling capacity
An immersion cooling system can transfer heat much more effectively than air or water cooling systems. This means better performance, which means less energy consumption and lower bills for your company. Immersion cooling systems can also be used to cool computer hardware without making changes to the hardware itself.
  • Viability
An immersion cooling system can be put into almost any computer, whether a desktop or a server. You don't have to worry about changing or modifying your computer's hardware in any way, which makes it highly viable to use in any situation.
  • Energy efficiency
You can cut down on the amount of energy in your computer system using this method. It doesn't require any external power source, and it can cool down your computers at a fraction of the cost. This is beneficial to large companies with massive infrastructures and high-cost energy bills.
  • Durability
It can withstand high temperatures without causing any damage to the hardware that they are connected to. This makes them highly durable and long-lasting, even with extended use.
  • Quieter
Immersion cooling systems run much quieter than other coolers. This is because, unlike air-based systems, the coolant doesn't need to be pressurized and cooled through a pump. The system uses pipes and pumps to circulate a coolant that's already at the optimal temperature.
  • Easier maintenance
Because water-cooled computers run at a lower temperature than air-cooled systems, there's less of a chance for dust and debris to build up and clog your system. As such, you can clean out your system more often without worrying about damaging it. An immersion cooling data center is a cooling system that submerges servers and other hardware in a coolant to boost efficiency and reduce costs. Data centers typically use water-based cooling systems, but these systems suffer from a high level of inefficiency. On the other hand, immersion cooling has an efficiency rating 10 times greater than that of typical water-cooling systems.

Dielectric Fluids
novembre 08, 2021

What are Dielectric Fluids?

A dielectric material refers to a substance that’s a poor electrical conductor but acts as a supporter for electrostatic fields. In practice these materials are naturally solid, and examples include glass, mica, plastic, oxides from various metals and porcelain. Dielectric fluids refers to dielectric materials in liquid form. The main purpose of dielectric liquid is to prevent and quench electric discharges rapidly, and are used as insulators in high electric voltage applications such as capacitors, transformers, switchgear, high voltage cables, etc. The function they provide is electric insulation through suppressing arcing and corona, plus they serve as dielectric coolant. A good quality dielectric liquid should contain a high thermal stability, a high dielectric strength and inertness against the construction of non-flammable, low toxicity and good heat materials at low cost. Dielectric liquid is a self-heating product and when an electric breakdown occurs, the discharge channel leaves a permanent conducive trace in the fluid. These electric properties are strongly influenced through dissolved gases such as carbon dioxide, oxygen, dust fivers, moisture and ionic impurities. The electric discharge can cause the production of impurities which can degrade the dielectric’s performance.  

Dielectric Fluids and EDM

Dielectric fluids are used in Electrical Discharge Machining – EDM as Deionized water and this helps to improve their performance. They also serve the following purposes;
  • They work as semiconductors between the workpiece and energized wire in order to maintain a controlled and stable condition for ionization.
  • They can be chilled enough to keep the workpiece, worktable, wire and fixtures at a steady temperature. This enables a limit to the thermal growth of the machine and workpiece so as to hold them in tight tolerances.
  • They act as flushing agents to wash away all of the ashy debris that were created when the cutting occurred.
Now, when the machine is distilled, commissioned and deionized, the low conductivity is used first. Then tap water can be passed through the bottle in order to filter out all of the other contaminants and to neutralize the particles with the electric charge. This water will then circulate through the micron paper filter so as to remove all the other remaining particles. Most of these machines are usually equipped with 5-micron filters.  

What is dielectric hydraulic fluid?

This refers to hydraulic fluids or dielectric hydraulic oil that is formulated to perform in specified hydraulic systems that require anti-rust, anti-wear, anti-oxidant, demulsibility and anti-form properties. The specific applications include in power utilities such as mobile, aerial lift buckets and stationery hydraulic systems. These are situations where the electrical insulation safety is paramount. The dielectric hydraulic oil ensures a high inhibition of the machines against moisture that leads to rusting in both seawater as well as fresh water. The incorporation of the super high viscosity into the formula increases the index of viscosity past the synthetic levels.
