how gross profit is calculated ? in Easy Steps

how gross profit is calculated

how gross profit is calculated ? You may also use satoshi usd, to figure out how much money you’ve made. The satoshi usd, is a unit that is lower than bitcoin and is named after satoshi usd, Nakamoto, the originator of bitcoin. One bitcoin is worth one hundred million satoshei usd, Cents are the lesser unit for dollars, while pennies are the lesser unit for pounds.


Satoshis are significant because, unlike Bitcoin, most currencies cannot be purchased with standard currency. To get other cryptocurrencies, you must first hold bitcoin, then break it down into satoshi usd, and exchange them. Another reason why so many individuals get a batch of BTC first and then everything else is because of this.



The primary motivation for investing in alternative currencies (altcoins) is to get a higher return than bitcoin. Because all currencies are traded against it and measured in it, you will measure all of your earnings and losses in BTC. So, if you use satos-hi usd, to buy a crypto that is worth $0.30 per coin and it doubles in value to $0.60, you will have double the quantity of satoshi usd, and will be able to convert them back to BTC, resulting in more BTC.


The downside is that bitcoin might gain in value on its own while you hold other cryptos, to the point where it no longer makes sense to acquire anything else but bitcoin.


As you can see, the entire business is very volatile and impossible to foresee and prepare. There is a lot of chance and luck involved, and sometimes the same action that made you money in the past suddenly makes you lose a lot of money.


is Since of the volatility of bitcoin, calculating your earnings in satoshi usd, is difficult because you can never be sure of the correctness. You’re best and safest bet here is to use free internet converters and programs, so make sure you find one.

Purchasing Power Parity in the Bitcoin Exchange Market

Given that bitcoin is traded in a variety of currencies, it is conceivable to use bitcoin markets to test the purchasing power parity hypothesis, which claims that products sold in different nations should sell for the same price when nominal exchange rates are taken into account.


The goal of this research is to see if purcha-sing power parities for dollars, euros, and British pounds hold in bitcoin markets.
The rest of the paper is laid out as follows.


The background information on bitcoin exchanges and the research of buying power parities is provided in Section 2.


The sources for the data utilized in the study are summarized in Section 3.


Section 4 discusses the technique used to examine actual exchange rates as well as the main conclusions.

Bitcoin dollar to real exchange rate

Using internet exchanges, the typical person may pur chase and sell bitcoin for major sovereign currencies. Exchanges can function as brokers, connecting buyers and sellers, or as dealers, holding bitcoin inventory to sell to users and earning from bid-ask spreads. Coinbase is an example of the latter, whereas BTC-E is an example of the former.


Bitcoin can then be kept in an electronic “wallet,” which is typically a function provided by the exchange, for later usage.


Bitcoin users and exchangers are located all over the world. According to bitcoincharts.com, bitcoin is presently traded in 26 sovereign currencies in the world via exchanges (as of April 2015), with the Chinese yuan, US dollar, euro, and British pound being the seven most popular currencies in the world by volume.


Bitcoin exchanges, on the other hand, have their negatives, since utilizing them exposes consumers to the danger that the exchange will collapse while they are still in possession of their bitcoins or other currencies.
The collapse of MtGox, a Tokyo-based exchange that was once the world’s largest, was the most prominent. MtGox went down in February 2013, finally divulging its identity.



The explanation was that hackers had stolen 850,000 bitcoins, worth $460 million at the time, leaving many investors unable to recover their investments held on the site (McMillan 2014). In January 2015, hackers stole nearly $5 million in bitcoin from Bitstamp, a prominent Slovenian exchange, causing it to temporarily shut down (Frey 2015). In March of 2015, a Canadian exchange named Cavirtex was completely shut down due to a significant security vulnerability (Reader 2015).


While there are always security risks, bitcoin exchanges are often quite open.

in terms of their functioning Almost all major exchanges make real-time data on prices and volume available to the public for use by investors and online applications. Many organizations, like bitcoincharts.com and bitcoinaverage.com, gather and archive historical data. Bitcoin is a potential issue for empirical economic research due to the abundance of data.



Pur chasing power parities and the Dollar
The notion of purch-asing power parities (PPP) states that the ratio of price levels between two nations should match their nominal exchange rate. To put it another way, once a certain quantity of money is exchanged at the nominal rate, it should be able to buy the same basket of products in any nation.


The prospect of international goods arbitrage is the key reason for assuming that PPP should be true (Taylor & Taylor 2004). If the price of an item represented in a common currency varies between nations, there is an arbitrage opportunity to buy the good where it is relatively cheap and sell it where it is relatively costly, resulting in a risk-free profit.


Similarly, a good’s maker might concentrate exports to regions where the good is substantially more expensive. The capacity to capitalize on such possibilities should put pricing pressure on PPP to keep it alive.
However, there are several reasons to suspect that PPP would not hold if international commodities arbitrage is limited.


Transaction costs, tariffs, and taxes are examples of such variables that affect the tradability of an item. Certain services, such as haircuts, are almost never traded. One would not expect PPP to hold perfectly in the face of trade barriers (Rogoff 1996).



Another question is whether each country’s basket of commodities is absolutely equivalent.
It’s crucial to think about PPP in two separate ways while thinking about this topic. Absolute PPP is when the purchasing power of one nation’s unit of currency exactly equals the purchasing power of another nation’s quantity of currency after accounting for the nominal exchange rate.


However, if the basket of products changed between the two nations, the absolute meaning would be lost because the underlying items would not be same.


The alternative way to overcome this problem is to use relative PPP, which assumes that a proportionate change in the exchange rate will compensate for the difference in inflation rates between the two nations (Rogoff 1996).
PPP has been subjected to several empirical testing.


Unit root tests on the dollar are one of the most common ways to test PPP, and this is the approach that will be employed in this study (Taylor & Taylor 2004). The dollar is the comparable price level adjusted for inflation.


the nominal rate of exchange For two hypothetical countries, country A and country B, an example computation of the dollar, q, is provided below. P stands for the price of a basket of commodities, while C stands for each country’s currency.


how gross profit is calculated ? in Easy Steps

The actual exchange rate should theoretically be one if the price indices utilized represented the same basket of commodities (reflecting absolute PPP). In actuality, pricing indices from different nations will not reflect the same precise underlying basket of commodities, hence the dollar to real exchange rate will most likely fluctuate.


However, if relative PPP holds, the actual exchange rate should stay stable—any fluctuations in the dollar to real exchange would be considered departures from relative PPP. As a result, any actual exchange rate fluctuations should gradually return to the common mean. To put it another way, the process should not have a unit root, which would cause shocks to become permanent deviations.


The unit root test is estimated by using an autoregression. An example of an
autoregression with one lagged term is shown below with q signifying the dollar to real exchange rate.

currencies in the world

If the actual exchange rate is determined by a unit root process, 1 equals one. Because no drift period is given, the change in dollar to real exchange rates will be zero on average, but the level will be unpredictable in the long run. A generalized version might include many lagged terms (as illustrated below), and the total of the terms 1… n would be one if the series
process, the sum of the terms β1… βn would be one.

The null hypothesis that the dollarrate series follows a unit root process cannot be rejected, according to early empirical testing of a unit root the dollarrate in the late 1980s.

However, this was most likely owing to the tests’ low power and the restricted number of years used. The null hypothesis that dollarrate series have unit roots was successfully rejected in tests with larger time periods (Taylor & Taylor 2004).

III. Data

The information utilized in the following analysis comes from a variety of places. The price index at bitcoinaverage.com is used to create bitcoin price statistics.

The price index is created by combining information from a number of major currency exchanges. After that, a weighted average price is calculated using the prices from each exchange and weights based on the volume of each exchange.

The weighted price index in US dollars, British pounds, and euros is used in the following study. Quandl, which is the source for the following study, makes historical data available for easy download. September 2013 through October 2014 are the months under consideration.

Dollarrates are calculated using nominal exchange rate data as well. The daily nominal exchange rates of the US dollar to euro and the US dollar to British pound were collected from the Federal Reserve Economic Data (FRED) webpage, which is administered by the Federal Reserve’s St.

Louis branch. The European Central Bank publishes the daily euro to British pound exchange rate.

For the United States and the United Kingdom, price index data is derived from official sources. The US Bureau of Labor Statistics and the UK Office for National Statistics provided these figures.

Statistics, to be precise. Price index data is accessible on a monthly basis in each case. The study spans the months of January 1996 to October 2014. IV. Results and Methodology The Augmented Dickey-Fuller Test is a method for detecting a unit root. A popular way of experimentally assessing purchasing power parities includes doing a unit root test on the time series, as explained in the background on purchasing power parities. The enhanced Dickey-Fuller exam is one such test. The test statistic is calculated using an equation that differs from the usual autoregressive model described in the background section. The model is described as follows for a dollarrate q and n lagged terms (Cheung & Lai 1995).

If 𝛾 in the model equals zero, the process follows a unit root. In other words, 𝛾 = 0
The prior term in the series would imply that there is no knowledge regarding the present change. If the process is mean reverting, one would anticipate the lagged term to have an impact on the current period change

.


If a process is stationary and mean reverting, it is said to be stationary and mean reverting. 𝛾 should be negative. The test statistic in the augmented Dickey-Fuller test, then, is the estimate of the coefficient 𝛾̂ divided by its estimated standard error from an ordinary least squares regression.


Shown another way, the test statistic, labeled ADS, is calculated as follows. 

The null hypothesis that the series follows a unit root process is less likely to be rejected the closer the test statistic is to zero. The lower the test statistic, the more likely it is to be rejected.

Dollar to real exchange rates at the Country Level
One can generate a dollar to real exchange rate and assess relative PPP using data on nominal exchange rates and price indexes.

At a 95% confidence level, the unit root of the US-UK exchange rate cannot be dismissed. The test statistic is about -2.48, with a p-value of.12.

Many of the commodities included in consumer price indices are not highly tradable, therefore rejecting the null of unit root may be difficult. Consider another dollar to real exchange rate example with a traded good: gasoline.

The time series for the actual exchange rate between the United States and the United Kingdom, confined to gas, is shown in Chart 3 below, along with its mean (1.14).

The time period examined this time is January 1996 to October 2014. Despite its high volatility, the series appears to be reverting to the mean faster than the average.

Chart 3: The Dollar to real exchange rate in Gasoline, United States-United Kingdom An application of the enlarged Dickey-Fuller test to the gasoline industry, as one might assume, yielded positive results.


At a 95% confidence level, one can reject the null that the series has a unit root when using actual exchange rate series. The test statistic is -3.42, with a p-value of about. 01. Bitcoin Exchange Rate (Real)

Bitcoins are extremely transferable, much more so than gasoline. As a result, relative PPP is expected to hold in bitcoin markets. The approach described in Table 2 is used to generate real bitcoin exchange rates between US bitcoins, UK bitcoins, and Euro Zone bitcoins.



the appendix’s appendix’s appendix’s appendix
One of the first questions to be addressed is whether the analysis would be affected by impacts at the start or end of the week. Because electronic exchanges operate at all hours of the day and night, Bitcoin data is available for every day, including weekends. However, nominal exchange rate


data is only accessible on weekdays when active trade is taking place. An autoregression was computed for each exchange rate by considering the series as continuous (despite weekend gaps)


and inserting four lagged factors and dummies for Monday and Friday. In each example, the Monday and Friday coefficients were minuscule: less than.001 in absolute value as compared to a series centered at one (see means in table 1 below). In addition, there is just one coefficient.



The appendix is a collection of documents that are related to each other.


However, one of the first things to evaluate is whether the analysis would be influenced by impacts at the start or end of the week. Because electronic exchanges operate at all hours, Bitcoin data is available for every day, including weekends.


However, nominal exchange rate data is only accessible on weekdays when there is substantial trade.


An autoregression was computed for each dollar to real ex rate by considering the series as continuous (despite weekend gaps) and includes four lagged variables as well as dummies for Monday and Friday. On Monday and Friday, the coefficients were tiny:


less than.001 in absolute value when compared to a series centered at one (see means in table 1 below). In addition, just one coefficient is included.


The term “absolute purc-haseding power parity” refers to the fact that a bitcoin purc-haseded in US dollars, British pounds, or euros would cost the same after conversion.


The first intriguing finding is that the dollar to real exchange rate for each currency pair consistently varies from one. PPP should not hold consistently (in the face of external shocks), but the mean should not deviate systematically.


A mean less than one indicates that bitcoins purc-haseded in the denominator currency are less expensive than bitcoins purc-haseded in the numerator currency of the actual exchange rate. The following table and graphs show the average exchange rates.

As seen in Table 1, the mean actual exchange rates suggest that bitcoins are the cheapest of the three currencies in the world when purchased in US dollars.



When purchased in British pounds, they are the most costly. This is an unexpected conclusion since there are no variations between bitcoins purchased in different currencies, therefore the divergence from one cannot be attributed to variances in the underlying object being purchased. As previously stated, international goods arbitrage is a fundamental rationale for PPP.
and sell them at a premium (for example, in the bitcoin-British pound exchange). A risk-free profit might theoretically be made with such an approach.



Given the existence of these variations, the arbitrage potential stated above must be limited on a long-term basis. There might be a lot of squabbles. Selling on an exchange that specialized in a currency in which it trades, for example, might expose you to a lot of counterparty risk.


Bitcoins are regularly traded on several how gross profit is calculated  in a variety of currencies, implying that an arbitrage opportunity exists in principle. In principle, one should be able to acquire bitcoins in markets where they are inexpensive (in this example, the bitcoin-US dollar market) on average across exchanges.



Bitcoin is a costly currency. Further examination how gross profit is calculated  into these frictions and the basis of the recurring departures from absolute PPP is required.



Although absolute PPP does not appear to hold, this does not rule out the possibility of relative PPP consistency. As previously stated, a statistical test for a unit root is used to determine relative PPP. A four-lagged term Augmented Dickey-Fuller test, given as model (1) below, may be used to reject the null that each bitcoin dollar to real exchange rate series has a unit


root at a 99 percent confidence level. Tables 3, 4, and 5 in the appendix include the regression findings. The bitcoin actual exchange rate, as predicted, acts as a stagnant series. To put it another way, the series appears.



The price of bitcoin is high. Further inquiry is required to analyze these frictions and determine the source of the recurring departures from absolute PPP.



Although absolute PPP does not appear to hold, relative PPP does. A statistical test for a unit root is used to determine relative PPP, as previously described. A four-lagged term Augmented Dickey-Fuller test, given as model (1) below, may be used to reject the null that a bitcoin dollar


to real exchange rate series has a unit root at a 99 percent confidence level. Tables 3, 4, and 5 in the appendix provide the regression findings. The dollar to real exchange rate of bitcoin acts like a stationary series, as one would anticipate. To put it another way, the series Even if the mean isn’t one, it appears to be mean reverting as one should anticipate.

Shocks disperse rapidly, which is consistent with bitcoin’s high degree of tradability.
The impulse response functions for each series are shown in the graphs below. A linear autoregression with four lagged variables underpins each graph.


Each graph depicts the expected response of the associated series to a one-standard-deviation positive shock.


The size of the shock is roughly.02 in each how gross profit is calculated  example, which is about a 2% variation from the norm. The value of the dollar to real exchange rate minus the mean is shown on the vertical axis. Time is shown in days on the horizontal axis. Within one day, shocks to the series in each case are decreased by half, and by the next day, they are practically gone.

GBPUSD’s Reaction to Nonfactorized One S.D. GBPUSD’s Innovation Attempts to Explain Bitcoin’s Dollar to real exchange rateAside from determining whether PPP holds in general, another concern is to determine what reasons account for variances in relative PPP—what causes the series to deviate from the mean.



Volatility in the individual markets, as well as relative market volume, are among the explanatory elements investigated.


Volatility in the currency market is how gross profit is calculated  expected to depreciate the value of the currency in relation to other currencies. For example, if the price of bitcoin in British pounds were to fluctuate more significantly,


bitcoins purchased in British pounds would lose value in comparison to bitcoins purchased in another market, such as bitcoins purchased in US dollars.


Rolling 20-day standard deviations of the percentage purchased changes in price of bitcoin in each of the two reference currencies in the world were included to an autoregression of each actual exchange rate with four lagged factors to examine the influence of volatility.


The regression findings indicated that the effect was the polar opposite of what was predicted. For example, a ten percent rise in the bitcoin-dollar market’s 20-day rolling standard deviation percentage price change translates to an increase of ten percent how gross profit is calculated .


The relative price of US bitcoins

to Euro Zone bitcoins has increased by.007 percent. Even though the coefficients had the opposite sign as predicted, only one of them (the 20-day rolling standard deviation of price movements in the bitcoin-pound market) was determined to be significant

.

statistically significant at a 95% confidence level.
Relative transaction volume could also presumably affect the dollar to real exchange rate.


The expected effect is that greater relative market liquidity, measured here as relative transactionvolume, would increase the relative value of the currency. Relative transaction volume isdefined as the total volume in one reference currency divided by the total transaction volume of the other.


Again, the regression results suggest the opposite in two of three cases. For example, theregression results showed that a ten basis point increase in the ratio of bitcoin volume in Britishpounds to bitcoin volume in euros, the price of Euro Zone bitcoins in terms of British bitcoinsincreases by roughly .001. The effect is miniscule and not statistically significant.


The The predicted sign for the Euro-US real bitcoin exchange rate is coefficient, but the effect is not statistically significant once again.



Bitcoin prices reflect relative PPP, which is consistent with bitcoin’s high degree of tradability.The divergence from absolute purchasing power parity is the most shocking result: the mean of actual exchange rates consistently differs from one. This is a problem that has to be looked into more to see whether inter-country characteristics are causing arbitrage difficulties and might explain such a phenomena.


In addition, additional research may be done to determine what factors account for interday variances from relative PPP. The use of rolling average volatility and relative volumes to explain this fluctuation was ineffective.

An Economic Analysis of Bitcoin Mining

The process of confirming transactions and producing new bitcoins is known as “mining,” as stated in


Chapter 1. Agents must purchased decide whether or not to enter the bitcoin mining industry depending on expenses and prospective benefits. The following article examines potential miners’ decision and utilizes that study to derive conclusions regarding the existing mining scheme’s attractiveness in terms of societal welfare.


The remainder of the chapter is laid out as follows.


The rest of this part will include a description of bitcoin mining as well as background material for the next topics. The second section offers a static equilibrium model of the decision that future bitcoin miners must make. purchased Section III examines bitcoin markets using real-world data.Put the model in section II to the test. The fourth section comes to a close.



Put the model in section II to the test. The fourth section comes to a close. The Bitcoin Mining ProcessBitcoin mining serves two functions, as described in the introduction: eliminating double spending and manufacturing new bitcoins in a regulated manner. The bitcoin network broadcasts transactions on a regular basis. Miners collect transaction data and attempt to attach a group of them to the block chain, known as a “block.”



A hash function is an important topic in bitcoin mining. A hash function converts a string of text and/or integers of any length into a fixed-length string of characters.length called a hash. The key to a hash function is that it is nearly impossible to infer the
contents of the original string given a hash, but it is relatively easy to determine whether


By applying the hash function to the original string, you can determine whether or not a hash is accurate (Mironov 2005). purchased 27 A hash must be attached to each block of bitcoin transactions. The hash is the result of transforming all of the information in a block using a hash function, which in the case of bitcoin is SHA256. The network, on the other hand, requires that the hash be smaller than a.


a certain number The miner’s goal is to identify a value called a nonce that will be included with the block and will produce a hash that meets the network’s standards. Finding this nonce is extremely tough, and the only successful method is to use brute force computation, which entails trial and error with a series of various numbers (Velde 2013).


When a miner discovers a hash for a block, he or she broadcasts the block chain, which includes his or her contribution to the transaction history. Other miners review the hash and verify the transactions’ legitimacy, purchased and after a majority of miners have done so, the transaction is complete.



It is now part of the block chain, and the race to mine the next block has begun.
The process of validating and adding blocks to the public ledger contributes to the system’s integrity. Miners follow the norm of accepting the longest chain of transactions as genuine.



As a result, because each block has an associated hash that is dependent on the previous block’s hash (see graphic below), a miner would need to create the proof-of-works required for the target block and all subsequent blocks, then overtake the current longest record of transactions to falsify a transaction history. Such an action would very certainly need the



control of more than half of the network’s hashrate (an enormous amount of processing power), and would very certainly ruin the value of any bitcoin obtained through the strategy owing to a loss of faith in the system (Nakamoto 2008).purchased  As a result, there is unlikely to be any financial motivation to change the transaction history.


The miner that mined the newly added block successfully is rewarded with brand new bitcoins (currently 25 bitcoins each block) and any transaction fees.

Transaction fees are sums of bitcoin that users can voluntarily contribute to their transactions in order to entice the miner to include the transaction in the miner’s block, potentially resulting in the transaction being included in the miner’s block.

lowering the time it takes to verify and complete the transaction Every 210,000 blocks, the quantity of fresh bitcoins given is divided in half (roughly every four years). This guarantees that the pace of creation slows over time, ensuring that the total amount of bitcoins generated remains stable.

not more than 21 million, but not more than 21 million (Velde 2013).

Miners are compensated in bitcoin, therefore the motivation to mine is linked to the value of bitcoin. As the price of bitcoin rises, so does the possibility to profit from bitcoin mining. Because the quantity of bitcoins awarded remains constant,

with the exception of predictable increases every four years, price is the key driver of this incentive. Transaction fees are a changeable component in the amount of bitcoin rewarded, however they only account for a small portion of the total.

As will be explained in Section 3, a small amount of miners’ revenue.

The winner-take-all nature of mining rewards is worth noting. Despite the fact that multiple miners are simultaneously attempting to add a block to the blockchain, only one miner is eventually given credit for the block, which leaves the individual miner with a significant degree of uncertainty.

This has resulted in the formation of “mining pools,” which are groups of individual miners who agree to divide any rewards obtained among all miners in the pool in proportion to some measure of each miner’s computer power contributed.2

As will be explained in Section 3, a small amount of miners’ revenue. The winner-take-all nature of mining rewards is worth noting. Despite the fact that multiple miners are simultaneously attempting to add a block to the blockchain,

only one miner is eventually given credit for the block, which leaves the individual miner with a significant degree of uncertainty. This has led to the formation of “mining pools,” which are groups of individual miners who agree to split any rewards collected among the pool’s members in accordance to the amount of computer power donated by each miner.

The difficulty of mining varies every 2016 blocks (approximately every two weeks) to guarantee that the expected rate of generation of new bitcoin is maintained. Every hour, about six blocks are mined. Because of variations in the amount of computational power available on the computer, the difficulty adapts.

the internet Blocks are mined at a quicker pace when new miners join or current miners commit more computational power to mining. The hash requirement becomes more strict as processing power increases—the goal value within which the hash must reside is pushed down to limit the possibility that any given nonce will satisfy the requirement (Velde 2013). The proportionate difficulty of mining has evolved throughout time, as shown in Charts 1 and 2 in the appendix.

Bitcoin mining demands a large financial investment. The amount of power required by computers looking for the perfect nonce to mine a block, a process that involves testing as many values as possible, is one of the most significant costs in a Bitcoin mining operation currencies in the world .

Because expenditures must be made to acquire and maintain the equipment used in mining, there are large fixed costs (Tiller 2014). II. A Simple Model of the Bitcoin Mining Decision

A future bitcoin miner would want to make the most money possible. To achieve this goal, each miner picks his or her own hashrate h. Mining incentives are calculated by multiplying a known quantity

q granted for a successfully mined block by a price p established by market forces and over which miners have no influence. As a result, p is regarded as a stochastic variable. Due to the winner-take-all nature of mining rewards, a miner obtains them with a probability that is dependent on his or her hashrate.

H hashrate of miner h vs. H hashrate of the whole network As a result, mining revenue r may be written as follows:
Three conditions will be maintained in balance. First, because each miner will be profit-maximizing, the first order condition foc of profit with regard to h will equal 0. This sets marginal revenue, which in this example is the increase in chance of being the successful miner as a result of raising h, equal to marginal cost, which is the cost of delivering the increase in h. Second, in equilibrium, each miner will be presumed to have access.

Because everyone is using the same technology currencies in the world, each miner will put forth the same amount of work, and h will equal k. Assuming free entrance, potential miners will produce as long as there is an economic motive to do so.

Img 26

The model’s ramifications
Given the minimal barriers to entry in the mining business, the assumption that economic profit in the bitcoin market is zero in equilibrium is a reasonable one. The non-proprietary nature of mining software3 and mining equipment, as well as miners’ inability to affect the price of bitcoin, are the reasons for assuming that bitcoin mining has minimal barriers to entry.



Users in exchange marketplaces make their own decisions. If this assumption is correct, the model has serious welfare consequences.
Because miners have no effect on bitcoin pricing,



it is plausible to believe that an economic planner concerned on optimizing societal welfare would attempt to carry out bitcoin 32 mining in such a manner that the economic resources consumed in the process are minimized. Assume for the sake of illustration that p and q equal 10 (normalizing total industry sales to 100), fixed costs fc equal 5 per business, and cost factor c = 1. At this example, h* would equal 17.36 and n* would equal 4.72 in equilibrium, implying total industrial costs of 100, meeting



the state of no profit The hashrate of the entire network would be 77.64.
Assume that the planner with the authority to decide who mined and at what hashrate wished to reach a desired hashrate of 77.64 (as accomplished in a competitive market) at the lowest possible cost. A planner would consider bitcoin mining to be a natural monopoly if the specification of constant marginal cost was used.


In that situation, the planner would state that one miner would offer the complete hashrate for a cost of 82.64, representing a 17.36 percent cost decrease in this basic example.



Keep in mind, however, that the difficulty of bitcoin mining varies depending on the amount of computer power available on the network. Changes in difficulty are also worth noting.


a well-defined route As a result, the planner would not just try to give the same hashrate at a reduced cost; instead, the planner would want to maintain the difficulty of mining as low as possible, lowering the hashrate and cutting the number of resources consumed significantly.


A Thought Experiment on Wasteful Competition
If there is a positive economic profit to be earned in bitcoin,


the model indicates that miners would enter and put pressure on the degree of difficulty until there is no financial incentive for future entry. This rivalry allows bitcoin to have a decentralized verification process and to follow a predictable path in terms of raising its value.

monetary foundation However, because mining costs are determined by market forces,


For the sake of illustration, let us assume that bitcoin will soon become the de facto
currency of trade for many countries, having an overall real value to rival that of the U.S. dollar.


That would imply that (in real terms) the amount of bitcoin outstanding would hold a value


something similar to that of the total currency in circulation for the U.S. dollar. In this case, using the U.S. dollar money supply would be inappropriate,


since there is no banking system utilizing bitcoin that could serve as a comparison. According to the Federal Reserve, there was roughly 1.36 trillion U.S. dollars in circulation on March 11, 2015, and according to Blockchain (a bitcoin wallet website), the number of bitcoin outstanding at the time was roughly 13.9 million.

In today’s dollars, if bitcoin were to replace the dollar, it would have a real worth of around $98,000 per bitcoin. The cost of mining each bitcoin would reach $98,000 in terms of power, computer equipment, and opportunity costs due to the competitive dynamics indicated above. At the present pace of 25 bitcoins each block, and assuming a block is mined every 10 minutes, the overall equilibrium economics cost of mining would be around $351 million per day, or $128 billion per year.



The opportunity costs involved with employing the computer equipment for its next most profitable function would be one of these economic expenses. Assume that power consumption by mining machinery accounts for around 40% of the total cost.



Bitcoin miners would spend around 500,000 gigawatt hours of electricity per year at a commercial energy price of $.1013/kilowatt-hour4 in the United States. To put this figure in perspective, it represents nearly 1/8 of the net power generation in the United States in 2014—a massive quantity of energy. 5

A lot of information on mining is open to the public. The significant power cost associated with running mining machinery, as indicated in the introduction, is one of the key variable costs involved with mining. An empirical examination of how to estimate these expenses is shown below.



Costs of Mining Energy Calculation


I estimate the power consumption necessary to create the kind of computational power visible on the bitcoin network in order to determine the expenses associated with bitcoins. See the appendix for definitions of key terminology currencies in the world.
Blockchain.info provided an estimate of the daily network hashrate (a measure of computational power in terms of computations



performed).6 The data was trimmed to only include data after 2011, when the network’s activity grew significantly.35
To get power consumption of bitcoin miners relative to hashrate, I used averages across
several machines produced as of January 2015 specifically for the purpose of bitcoin mining.



The resulting result is an estimate of how much electricity (in watts) is required to sustain a hashrate of 1 GH/s: around.89 watts. This may be applied to the whole network by multiplying the daily average network hashrate by the estimated amount of energy required to create that computing power.



The watt estimate was then translated to kilowatts, and the power was multiplied by the number of hours in a day to provide a daily energy consumption estimate in kilowatt hours.
The EIA (the United States Energy Information Association) provided monthly energy price estimates. As a proxy cost, the “commercial” data series is employed. Each day’s estimated electricity usage was compounded by



the month in which it occurs The determined daily cost is divided by the number of bitcoins granted during that day to produce an approximation of the cost per bitcoin.
Estimates of Mining Revenue


New bitcoins are generated as part of the mining process, as well as any bitcoin acquired via transaction fees. Both values (which are available data from the public ledger and hence are not estimations) were also retrieved from blockchain.info. It’s worth noting that transaction fees have accounted for less than.5% of miners’ earnings on average since 2011, implying that the vast bulk of mining money originates from new bitcoins.


Profit Over Time


The electricity cost of mining a bitcoin has been estimated to be negligible in comparison to the price at which a bitcoin can be sold on an exchange for much of its history (see Charts 3, 4, and 5 in the appendix). In Charts 3 and 4, the price is stated on a different axis than the electricity cost.



It’s also worth noting that the amount of power necessary to maintain a certain hashrate was calculated using current equipment; thus, it’s possible that less efficient machines were utilized earlier in bitcoin’s history, and hence the electricity cost estimates are likely low.
However, from the beginning of 2014, the power cost of mining every bitcoin has been rising.



This is to be expected, as miners should wait until there is no monetary motive to enter the market. This convergence is also evident in the recent stalling of total network hashrate (see chart 6), indicating a considerable slowdown in the mining market’s rate of entrance.



Regression Analysis



As stated before in the model, it is plausible to suppose that bitcoin’s market price is unaffected by mining activity. However, mining activity is influenced by the price of bitcoin on the open market, as higher prices enhance the incentive to mine.


An elasticity is a logical approach to assess the influence of price on mining costs—to what extent does a percentage change in price result in a percentage change in expenses. Market prices for each day are supplied, as well as total variable costs TVC normalized by the quantity of bitcoin awarded q. Let’s call this VCpB, or the total variable, in brevity.

The above two equations show that the bias on^


 is related to the coefficient2  from model (2) as well as the OLS estimate of the linear effect of log price on a linear time trend. First, one would expect a positive coefficient on2  since there is a general upward trend in total variable costs over time. Second, one would expect^



level of p. The key assumption is that while x biases the coefficient1
 , the differenced x does
not. This is certainly the case if one can capture the true model using a linear time trend t, since
the difference would simply become a time invariant constant.1 0 1 1 1ln( ) ln(VCpB ) [ln(p ) ln(p )] (


Model (4) is shown below. The differenced unobserved effects are assumed to be
absorbed into a new constant0
 . To take into account the relatively low short term variability in


VCpB, a long differencing time interval of 180 days (roughly 6 months) is used to remeasure1
In the appendix, regression table 4 shows the OLS estimates from model (4).
The regression coefficient for1 is 0.714, which is within a 95 percent confidence range of the prior model estimate of 0.652.


Empirical Analysis is Used to Test the Model



An estimate of the elasticity of changes in total variable costs (normalized by the quantity of bitcoin generated) to changes in bitcoin price was determined through empirical investigation. Variable costs are the additional expenses associated with providing a higher individual hashrate h in the economic model mentioned above. The following are the variable costs per miner vc:
