Ferberite mining bitcoins
The streak of a mineral is independent of trace elements [73] or any weathering surface. By definition, minerals have a characteristic atomic arrangement. Weakness in this crystalline structure causes planes of weakness, and the breakage of a mineral along such planes is termed cleavage. The quality of cleavage can be described based on how cleanly and easily the mineral breaks; common descriptors, in order of decreasing quality, are "perfect", "good", "distinct", and "poor".
In particularly transparent minerals, or in thin-section, cleavage can be seen as a series of parallel lines marking the planar surfaces when viewed from the side. Cleavage is not a universal property among minerals; for example, quartz, consisting of extensively interconnected silica tetrahedra, does not have a crystallographic weakness which would allow it to cleave.
In contrast, micas, which have perfect basal cleavage, consist of sheets of silica tetrahedra which are very weakly held together. Cleavage occurs typically in either one, two, three, four, or six directions. Basal cleavage in one direction is a distinctive property of the micas. Two-directional cleavage is described as prismatic, and occurs in minerals such as the amphiboles and pyroxenes. Octahedral cleavage four directions is present in fluorite and diamond, and sphalerite has six-directional dodecahedral cleavage.
Angles between cleavage planes vary between minerals. For example, as the amphiboles are double-chain silicates and the pyroxenes are single-chain silicates, the angle between their cleavage planes is different. The cleavage angles can be measured with a contact goniometer, which is similar to a protractor. Parting varies from crystal to crystal of a mineral, whereas all crystals of a given mineral will cleave if the atomic structure allows for that property.
In general, parting is caused by some stress applied to a crystal. The sources of the stresses include deformation e. Minerals that often display parting include the pyroxenes, hematite, magnetite, and corundum. There are several types of uneven fracture. The classic example is conchoidal fracture, like that of quartz; rounded surfaces are created, which are marked by smooth curved lines.
This type of fracture occurs only in very homogeneous minerals. Other types of fracture are fibrous, splintery, and hackly. The latter describes a break along a rough, jagged surface; an example of this property is found in native copper. Whereas fracture and cleavage describes the surfaces that are created when a mineral is broken, tenacity describes how resistant a mineral is to such breaking. Minerals can be described as brittle, ductile, malleable, sectile, flexible, or elastic.
Specific gravity numerically describes the density of a mineral. Among most minerals, this property is not diagnostic. Rock forming minerals — typically silicates or occasionally carbonates — have a specific gravity of 2. A variation in chemistry and consequently, mineral class correlates to a change in specific gravity. Among more common minerals, oxides and sulfides tend to have a higher specific gravity as they include elements with higher atomic mass.
A generalization is that minerals with metallic or adamantine lustre tend to have higher specific gravities than those having a non-metallic to dull lustre. For example, hematite , Fe2O3, has a specific gravity of 5. A very high specific gravity is characteristic of native metals ; for example, kamacite , an iron-nickel alloy common in iron meteorites has a specific gravity of 7. Other properties can be used to diagnose minerals. These are less general, and apply to specific minerals.
This test can be further expanded to test the mineral in its original crystal form or powdered form. An example of this test is done when distinguishing calcite from dolomite , especially within the rocks limestone and dolomite respectively. Calcite immediately effervesces in acid, whereas acid must be applied to powdered dolomite often to a scratched surface in a rock , for it to effervesce. Among common minerals, magnetite exhibits this property strongly, and magnetism is also present, albeit not as strongly, in pyrrhotite and ilmenite.
Halite , NaCl, is table salt; its potassium-bearing counterpart, sylvite , has a pronounced bitter taste. Sulfides have a characteristic smell, especially as samples are fractured, reacting, or powdered. The radioactive elements could be a defining constituent, such as uranium in uraninite , autunite , and carnotite , or present as trace impurities, as in zircon.
The decay of a radioactive element damages the mineral crystal structure rendering it locally amorphous metamict state ; the optical result, termed a radioactive halo or pleochroic halo , is observable with various techniques, such as thin-section petrography. His classification was influenced by the ideas of his teachers Plato and Aristotle.
Theophrastus classified minerals as stones, earths or metals. He divided the natural world into three kingdoms — plants, animals, and minerals — and classified each with the same hierarchy. However, while his system was justified by Charles Darwin 's theory of species formation and has been largely adopted and expanded by biologists in the following centuries who still even use his Greek- and Latin-based binomial naming scheme , it had little success among mineralogists although each distinct mineral is still formally referred to as a mineral species.
Modern classification See also: Abundance of elements in Earth's crust Minerals are classified by variety, species, series and group, in order of increasing generality. The basic level of definition is that of mineral species, each of which is distinguished from the others by unique chemical and physical properties. For example, quartz is defined by its formula , SiO2, and a specific crystalline structure that distinguishes it from other minerals with the same chemical formula termed polymorphs.
When there exists a range of composition between two minerals species, a mineral series is defined. For example, the biotite series is represented by variable amounts of the endmembers phlogopite , siderophyllite , annite , and eastonite. In contrast, a mineral group is a grouping of mineral species with some common chemical properties that share a crystal structure.
The pyroxene group has a common formula of XY Si,Al 2O6, where X and Y are both cations, with X typically bigger than Y; the pyroxenes are single-chain silicates that crystallize in either the orthorhombic or monoclinic crystal systems. Finally, a mineral variety is a specific type of mineral species that differs by some physical characteristic, such as colour or crystal habit.
An example is amethyst , which is a purple variety of quartz. James Dwight Dana , a leading geologist of his time, first published his System of Mineralogy in ; as of , it is in its eighth edition. The Dana classification assigns a four-part number to a mineral species.
Its class number is based on important compositional groups; the type gives the ratio of cations to anions in the mineral, and the last two numbers group minerals by structural similarity within a given type or class. The less commonly used Strunz classification , named for German mineralogist Karl Hugo Strunz , is based on the Dana system, but combines both chemical and structural criteria, the latter with regards to distribution of chemical bonds. However, non-silicate minerals are of great economic importance, especially as ores.
There are two major structural styles observed in non-silicates: close-packing and silicate-like linked tetrahedra. Close-packed structures are a way to densely pack atoms while minimizing interstitial space. Hexagonal close-packing involves stacking layers where every other layer is the same "ababab" , whereas cubic close-packing involves stacking groups of three layers "abcabcabc".
The non-silicates have great economic importance, as they concentrate elements more than the silicate minerals do. Other common elements in silicate minerals correspond to other common elements in the Earth's crust, such as aluminium, magnesium, iron, calcium, sodium, and potassium. Silicates Main article: Silicate minerals Aegirine , an iron-sodium clinopyroxene, is part of the inosilicate subclass.
In the vast majority of cases, silicon is in four-fold or tetrahedral coordination with oxygen. In very high-pressure situations, silicon will be in six-fold or octahedral coordination, such as in the perovskite structure or the quartz polymorph stishovite SiO2.
In the latter case, the mineral no longer has a silicate structure, but that of rutile TiO2 , and its associated group, which are simple oxides. These silica tetrahedra are then polymerized to some degree to create various structures, such as one-dimensional chains, two-dimensional sheets, and three-dimensional frameworks.
The basic silicate mineral where no polymerization of the tetrahedra has occurred requires other elements to balance out the base 4- charge. In other silicate structures, different combinations of elements are required to balance out the resultant negative charge. Disilicates or sorosilicates Have two tetrahedra sharing one oxygen atom.
Inosilicates are chain silicates Single-chain silicates have two shared corners, whereas double-chain silicates have two or three shared corners. Phyllosilicates Have a sheet structure which requires three shared oxygens; in the case of double-chain silicates, some tetrahedra must share two corners instead of three as otherwise a sheet structure would result. Framework silicates or tectosilicates Have tetrahedra that share all four corners.
Ring silicates or cyclosilicates Only need tetrahedra to share two corners to form the cyclical structure. Tectosilicates Natrolite is a mineral series in the zeolite group; this sample has a very prominent acicular crystal habit.
Tectosilicates, also known as framework silicates, have the highest degree of polymerization. With all corners of a tetrahedra shared, the silicon:oxygen ratio becomes V and Golden Valley Mines Ltd. V all have very interesting gold properties and mines near Val-d'Or.
It's another example of a project that can do well with good prices of gold. It is underground mining, which is a bit more difficult, but it has developed the expertise and holds a large property sitting on important favorable metallotects of the Val-d'Or camp. Moreover, Wesdome has recently made a new gold discovery on its property, which will certainly ensure mill feed for the next few years at its Kiena mine. Agnico-Eagle, with its Goldex mine, also has had good success mining its large-volume, lower-grade deposit underground using a shaft and its approximately 10,tons-per-day mining facilities.
TGR: But it has shut down that operation recently because of underground instability and some water-related issues. A-JB: That is right. Goldex did have some problems with rock stability and water infiltrations. Agnico-Eagle is presently reviewing all of this with several engineering firms. I'm sure the solution will soon be found and the mine should resume this coming year.
It's a project near the Cadillac Break, where rock mechanics change when moving outside the competent host mineralized rock, such as massive granitic and dioritic intrusions. The mine is also in close proximity with sheared volcanic rock. Studies are being done now to find solutions that will lead to start the mine next year. Since , about 25 Moz gold was discovered in the Val-d'Or and Malartic gold camps. There is still a lot of potential. The Val-d'Or, Malartic and Cadillac camps have been at work for the past 80 years, and I think they will be successful for another 80 years if the price of gold keeps up.
That mine produced more than 4. The Sigma gold mine is northeast of Integra's Lamaque property. It remains in production and has around, I believe, 5 Moz in resources and reserves. Teck Hughes closed that operation in the s. It had been at work since It produced close to 5 Moz. Integra Gold's Lamaque property is very well located in respect to the old Lamaque mine. When we took that project about two and a half years ago, we had about Koz of gold. We're pretty proud of having had the honor to work on that project for which we have a very special interest since I was mine geologist at the nearby Sigma mine between and for Placer Dome.
TGR: You probably need to triple that resource to get a mine into production. Do you think there's that much gold there? A-JB: If we keep on working the lateral and depth extensions of the already known mineralized zones, we should be able to improve the resources to the 1 Moz level. The strategy is to find altered fractured intrusions, just like in all the zones that brought the mineralization up to date. The Forestel zone, the Parallel zone, the Triangle zone, the Sixteen zone all have similar patterns of mineralization, typical of mesothermal vein-type deposits.
Some make sizeable ellipsoidal vein clusters, and we'll be able to bulk mine some of them. We could perhaps start an operation even before we reach the 1. Several unexplored targets remain to be tested yet. TGR: What are you looking at in terms of head grade? What's the average head grade? A-JB: It varies. We have zones with an average of 18 grams g. No two zones are the same, and some are obviously richer than others. We'll have to take into account all these variations and see how the mining of these zones independently or together will be done.
Will the ore be blended or will the deposits be mined individually? This is all part of our future studies. TGR: Is it more likely to follow the model of a Goldex and an underground bulk-tonnage operation, or is it more likely to be a pit? A-JB: Some zones will be open-pittable because they're close to surface and the overburden is not thick.
Other zones will need to be mined by underground bulk tonnage methods, preferably ramps, which are cheaper than shafts. We already have some infrastructure on the property. There are four or five old shafts, which could permit access to deeply located zones such as the No.
All options have to be considered. TGR: Last question on Integra. In terms of gold recovery, have tests been done to date on recovering the gold? Is it easy to recover? There are very little sulfides associated with the veins. It's very simple at Lamaque. The history speaks for itself.
I'm not worried at all for Integra thanks to Integra's management team, shareholders' continuous support, perseverance and successful financing. What do you know about Matamec Explorations Inc. A-JB: We haven't worked on that project.
With a solid partner such as Toyota, Matamec should be promised a successful future. Our involvement with rare earth minerals was and is with Quest Rare Minerals Ltd. A on the Strange Lake deposit. TGR: Where is this? It was discovered by Iron Ore Company of Canada in the s.
Quest Rare Minerals was able to drill anomalous till and soil geochemistry anomalies, which correspond with TREO-rich peralkaline intrusions. Aurizon Mines has a property that's contiguous to Matamec's Kipawa deposit; are people talking about that? It's closer to the Ontario border, and the geology there is favorable for rare earth minerals discoveries. There is a big interest and a lot of activity around rare earth and lithium.
V and Nemaska Exploration Inc. TGR: Do you believe there will be more of these kinds of deposits discovered in western Quebec? A-JB: I think so. It's just a matter of being able to constantly fund the research and exploration programs.

Only 1 megabyte of transaction data can fit into a single bitcoin block. The 1MB limit was set by Satoshi Nakamoto, and this has become a matter of controversy because some miners believe the block size should increase to accommodate more data, which would effectively mean that the Bitcoin network could process and verify transactions more quickly. Why Mine Bitcoin? In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation.
In other words, miners are basically "minting" currency. For example, as of March , there were just under 19 million bitcoins in circulation, out of a total of 21 million. Aside from the coins minted via the genesis block the very first block, which founder Satoshi Nakamoto created , every single one of those bitcoins came into being because of miners. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin.
However, because the rate of bitcoin "mined" is reduced over time, the final bitcoin won't be circulated until around the year This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid fees for doing so in order to keep the integrity of Bitcoin's network. To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem.
This process is also known as proof of work PoW. To begin mining is to start engaging in this proof-of-work activity to find the answer to the puzzle. No advanced math or computation is really involved. You may have heard that miners are solving difficult mathematical problems—that's true but not because the math itself is hard. What they're actually doing is trying to be the first miner to come up with a digit hexadecimal number a " hash " that is less than or equal to the target hash.
It's basically guesswork. So it is a matter of randomness, but with the total number of possible guesses for each of these problems numbering in the trillions, it's incredibly arduous work. And the number of possible solutions referred to as the level of mining difficulty only increases with each miner that joins the mining network. In order to solve a problem first, miners need a lot of computing power.
Aside from the short-term payoff of newly minted bitcoins, being a coin miner can also give you "voting" power when changes are proposed in the Bitcoin network protocol. In other words, miners have some degree of influence on the decision-making process for matters such as forking. The more hash power you possess, the more votes you have to cast for such initiatives. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC.
By , this was halved again to On May 11, , the reward halved again to 6. Not a bad incentive to solve that complex hash problem detailed above, it might seem. To keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real time.
Interestingly, the market price of Bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and, historically, the price has risen with it. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site CryptoCompare offers a helpful calculator.
Other web resources offer similar tools. What You Need to Mine Bitcoins Although individuals were able to compete for blocks with a regular at-home personal computer early on in Bitcoin's history, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time.
In order to ensure the blockchain functions smoothly and can process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are 1 million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks.
When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. Mining hardware All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC.
Some miners—particularly Ethereum miners—buy individual graphics cards as a low-cost way to cobble together mining operations. Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins.
Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. An analogy Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it.
And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners, and I'm thinking of a digit hexadecimal number.
Now you see that it's going to be extremely hard to guess the right answer. If B and C both answer simultaneously, then the system breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block.
Miners who successfully solve the hash problem but haven't verified the most transactions are not rewarded with bitcoin. Here is an example of such a number: fcccfd95e27ce9fac56e4dfee The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal.
This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or zero through nine. In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash.
I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope? In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible.
A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on Earth would you want to do that?
The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block No. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by AntPool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below.

All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number: ffff The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty.
Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner: Note: These are made-up hashes. Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings.

Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions. Not great odds if you're working on your own, even with a tremendously powerful mining rig.
Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution. All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing.
The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits. The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own.
For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners.
By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners. Statistics on some of the mining pools can be seen on Blockchain. A Pickaxe Strategy for Bitcoin Mining As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges.
Alternately, you can always leverage the "pickaxe strategy. To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. Downsides of Mining The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment.
That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment. One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms.
Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress. As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits.
Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control. Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort.
Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Because they are entirely digital records, there is a risk of copying, counterfeiting, or double-spending the same coin more than once. Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise "hack" the network. Indeed, it is far more cost-effective to join the network as a miner than to try to undermine it.
How Does Mining Confirm Transactions? In addition to introducing new BTC into circulation, mining serves the crucial role of confirming and validating new transactions on the Bitcoin blockchain. This is important because there is no central authority such as a bank, court, government, or anything else determining which transactions are valid and which are not.
Instead, the mining process achieves a decentralized consensus through proof of work PoW. In the early days of Bitcoin, anybody could simply run a mining program from their PC or laptop. But as the network got larger and more people became interested in mining, the mining algorithm became more difficult.
This is because the code for Bitcoin targets finding a new block once every 10 minutes, on average. If more miners are involved, the chances that somebody will solve the right hash quicker increases, and so the difficulty increases to restore that minute goal. Now imagine if thousands, or even millions more times that mining power joins the network. That's a lot of new machines consuming energy. Is Bitcoin Mining Legal? The legality of Bitcoin mining depends entirely on your geographic location.
The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not. Some examples of places where it was illegal according to a report were Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan.
Overall, Bitcoin use and mining remain legal across much of the globe. Because blockchain mining is very resource-intensive, it can put a large strain on your GPU or other mining hardware. In fact, it is not unheard of for GPUs to blow out, or for mining rigs to burst into flames.
However, keeping your rigs running at a moderate pace and with sufficient power supplied, it is generally safe. Bitcoin mining today requires vast amounts of computing power and electricity to be competitive. Running a miner on a mobile device, even if it is part of a mining pool, will likely result in no earnings. The Bottom Line Bitcoin "mining" serves a crucial function to validate and confirm new transactions to the blockchain and to prevent double-spending by bad actors.
It is also the way that new bitcoins are introduced into the system. You can review bitcoin payment proof in our payout section.
