The Political Geography and Environmental Impacts of Cryptocurrency Mining
As a part of our ongoing effort to educate Bitcoin investors, CoinShares publishes bi-annual reports on the inner workings and development of the Bitcoin mining network. Much has happened since our first report in May.
In fact, more than could be reasonably covered in a single Medium post, so I decided to break out some key takeaways into two posts. For those unfamiliar with the lingo I am about to employ, when I use the term capex I am referring to capital expenditures, and when I use the term opex I am referring to operational expenditures.
Briefly explained:. Capex describes all expenditures related to the acquisition of capital , such as mining gear, racks, property if applicable etc. Opex describes all ongoing expenditures, like wages, electricity cost, rent if applicable etc.
I will also be using the term ROI which simply means return on investment. ROI is positive if an investment is profitable, and negative if it produces losses. On one end of the scale, you can rent all your equipment, housing, maintenance, etc. Under this setup, all expenditures are opex and your operation owns no capital. If nothing is contracted, you have no assets and no liabilities.
On the other end of the scale, you could decide to buy all of your gear, a plot of land, and fixed electricity and employment contracts. In this structure, all expenditures are pre-paid capex. Your operation owns capital assets but also has contractual liabilities. For example, some may own gear, but rent space and pay as they go for electricity. Others rent gear, own land, and buy electricity on short contracts.
The point is that many miners have both capex and opex components to their cost function, and our assumption is that on average , most mining operations have a bit of both. More on this later. Mining gear, like most other productive capital has a finite lifetime and will see its productivity deteriorate over time until it is either worn out or obsolete.
This is the concept of depreciation. In practice, it means that mining gear must generate more free cash-flow over its lifetime than its acquisition cost plus ongoing capital costs in order to be profitable. The value of the gear you have is therefore understood to depreciate from its acquisition cost down to either scrap cost or zero.
If your gear is productive for a long time, it has a long depreciation horizon; conversely if it is only productive for a short time, it has a short depreciation horizon.
Free cash-flow here refers to cash-flow that exceeds all of your opex. As soon as opex exceeds income and mining gear becomes cash-flow negative, it no longer makes sense to even leave on, as it is now just burning cash.
In our report we calculate a market-average all-in breakeven cost for creating one bitcoin. This is our best approximate for the bitcoin creation cost above which the market-average miner will make a positive ROI.
At the risk of repeating myself ad nauseum here, this is not the level below which miners will turn off their gear. It is simply the level below which they will lose money on their investment, making them unlikely to remain players in the mining industry over time, unless they have bottomless pockets of investment capital available.

Some have it better, some have it worse. Pretty close to current bitcoin prices. At the time of writing, Bitcoinwisdom projects the next downwards adjustment to be even larger. The combined back-to-back decrease would be one of the largest in Bitcoin history, certainly the largest since the advent of large-scale professional mining around Or perhaps our cooling cost assumptions are too high?
While we can speculate about this, that is also ultimately all we can do. Bitcoin is structured such that the hashrate follows price, slightly modulated by increases in gear efficiency. When the price increases, the hashrate increases, and when the price decreases the hashrate decreases. Like any other capital-driven industry, the delay in the upwards drag results from the time difference between making an investment decision and when the gear is actually switched on.
For most players in bitcoin mining, this is on the order of months and depends on their proximity and relationships with the producers of mining gear. But even for the producers themselves, there is significant delay. Chips must be ordered from the foundry; units must be assembled, shipped and installed. Only at the end of that process does the hashrate actually increase.
In the meantime, the price could have increased even more, and much more rapidly than new gear could have possibly been employed. The same dynamic does apply in the opposite direction. When cash cost falls below breakeven, there are no barriers preventing miners from immediately pulling the plug on their gear, meaning that mining gear can be shut off immediately in response to falling prices. Side bar: the notable exception to this are mining operations that bought fixed supply electricity contracts, thus forcing them to mine until they are insolvent.
Miners are compensated in bitcoin, but incur costs in their local currency. Under a steady hashrate marketshare, the bitcoin exchange price is directly proportional to their payout. At average competitive conditions, increasing your hashrate in a falling market will only make you lose money, as mining costs will increase in line with the difficulty increases caused by increasing hashrates. This is in the unlikely event where miners are so well capitalised that they could refuse to sell their bitcoins at market prices, and cover their costs with liquid capital from their balance sheet while continuing to mine at a loss.
You be the judge of that likelihood. There is nothing dramatic about what is currently happening. The net effect is that the highest marginal cost producers are booted off the market while the most efficient miners remain.
Through this process, mining migrates ever closer to the cheapest underlying conditions. Meanwhile, bitcoin issuance effectively remains the same.
No fewer bitcoins are created, just as no more bitcoins were created during the period of price growth with the exception of single-digit perturbations caused by the relative over- or- underperformance caused by the growth or shrinkage happening between difficulty resets. If the price of gold increases, production will increase until the marginal production cost again equals the market price minus transport costs, which for bitcoin, are negligible compared to physical commodities.
If the price falls, production will decrease until the same condition holds. This dampens volatility by increasing supply in rising price markets and reducing supply in falling markets.
No such effect in Bitcoin. Issuance is predefined and no market dynamics can significantly influence it. As price does its thing, hashrate will follow and settle into whatever new market conditions are in stall. Old, inefficient gear and high-cost producers are out; and until price increases again, the hashrate can only increase by miners lowering their opex. They can do this by sourcing cheaper electricity, installing more efficient mining equipment or generally cutting costs.
For such a collapse to occur, the bitcoin price would need to immediately plunge to near zero; thus triggering virtually the entire mining network to shut down; and therefore preventing the requisite blocks to reach the next difficulty reset from being mined for months or even years.

Digital assets and related technologies can be extremely complicated. The digital sector has spawned concepts and nomenclature much of which is novel and can be difficult for even technically savvy individuals to thoroughly comprehend. The sector also evolves rapidly. With increasing media attention on digital assets and related technologies, many of the concepts associated therewith and the terms used to encapsulate them are more likely to be encountered outside of the digital space.
Although a term may become relatively well-known and in a relatively short timeframe, there is a danger that misunderstandings and misconceptions can take root relating to precisely what the concept behind the given term is.

So what does this all mean for the network? Briefly explained: Capex describes all expenditures related to the acquisition of capital , such as mining gear, racks, property if applicable etc.
When establishing a mining operation you can structure it between two extremes: On one end of the scale, you can rent all your equipment, housing, maintenance, etc. With longer depreciation schedules, you have more time to spread out the total purchase price.
For miners, there are two cutoff levels for bitcoin prices that matter: The first is their all-in ROI breakeven level, above which they make a profit on their investment, and below which they make a loss on their investment. So what does that mean? Essentially one of two things: Either our assumptions are silly, or… Many miners are currently feeling the squeeze, with inefficient mining gear and high-cost electricity miners likely to be forced off the network.
What does the data say? Clearly, some miners are struggling. They have gear that is running below cash cost which means this gear is now being shut off. Download the latest Bitcoin Mining Report An Important Note: Price and Hashrate Dynamics Bitcoin is structured such that the hashrate follows price, slightly modulated by increases in gear efficiency.
Mining cost will always tend towards the price of bitcoin minus a narrow competitive margin. However, these dynamics are not instant, and there is an asymmetrical delay in the trailing effects. Hashrate will therefore lag price increases on the order of months, but respond much quicker to decreases in price.
And moreover, how could that possibly be the case?
Efficiency of bitcoin mining hardware
The profits can be handsome, but there is a catch. The computer farms that mine coins consume considerable electricity. And in Iran, where electricity is subsidised, crypto miners have been accused of profiting at the expense of the state. Last fall, government officials acknowledged crypto mining as an official industry in Iran. That stamp of legitimacy — combined with cheap power and the allure of crypto as a hedge against rampant inflation triggered by harsh United States economic sanctions against Iran — has fueled a sharp increase in the number of Iranian crypto miners.
