Bitcoin Mining Profitability & Margins

Most Bitcoin investors and enthusiasts understand the process of mining. Over the past 12 years, the mainstream public has had plenty of opportunities to understand the network’s reward system for those who verify transactions on the blockchain.

However, the actual competitiveness of the industry and the profitability of mining is still a complex topic shrouded in mystery for many.

How are Bitcoin Mining Margins Calculated?

Bitcoin miners have various methods of reporting their Bitcoin mining margins and profits. Argo Blockchain uses a formula is consistent with the majority of miners in the industry. There are a number of factors involved in calculating Bitcoin mining profitability. Below is a formulaic representation of how Argo reports its operational updates. We will also discuss a number of methods one could use to reduce the expenses and improve the overall profitability of Bitcoin Mining we'll discuss further below.

Bitcoin Mining Revenue Model

Here at Argo, we try and keep it as simple as possible. Argo Blockchain's Investor Presentation, provides a deeper dive into how we generate profits for our company but we also believe everyone should have access and try to run the numbers themselves. The bitcoin mining formula below references the revenue side of the equation. There are a number of assumptions that go into calculating the Annual Gross Mining Profitability.

Here is Perry Hothi, Argo Blockchain's Chief Technology Officer, explain various metrics used to measure Bitcoin Mining Efficiency.

Bitcoin Mining Expense Model

Expenses involved in Bitcoin mining are straight forward compared to other business models. There's the cost of ASICs, the depreciation of existing miners, cost of maintaining the location and uptime of your ASICs, and most importantly the cost of electricity. Some of the other key factors to consider for a successful mining operation are hardware price, hardware availability, the climate of Bitcoin mining facilities location access to power.

Depreciation is an important accounting adjustment. In the United States, you have a choice to depreciate the value of any of the following machinery, equipment, buildings, vehicles, and furniture over a period of time. Basically, this accounts for expensing the useful life of the machine. Bitcoin mining would fall under "equipment", check out the article on how to calculate the annual depreciation expense of your Bitcoin mining ASICs.

So What's the Final Cost to Mine One Bitcoin?

First we need to understand that you can't mine just one Bitcoin. There is a block reward which means each time a Bitcoin miner is rewarded for validating transactions on the blockchain, they'll receive 6.25 Bitcoin. There is however a method of being rewarded in fractional terms and that requires that you work with a Bitcoin mining pool.

A Bitcoin mining pool is just a group of miners who combine their computational resources over a network to strengthen the probability of finding a block or otherwise successfully validating a transaction on the bitcoin blockchain network. Once again, Perry Hothi offers a quick explanation of what a mining pool is.

Utilizing a mining pool combines your efforts. For a modest fee, a mining pool pays out fractional rewards based on the contribution of hash rate you contribute to the pool.

So to bring it all together, what is the cost of mining one Bitcoin? It depends on how you choose to set up your operation, the network difficulty at the time, and the methods used to optimize your mining operation. Above all else, the most important factors that determine the cost of mining one Bitcoin is the cost of electricity and mining difficulty.

Bitcoin Network Difficulty Adjustments

As more miners enter the network and compete to earn the block reward, the network difficulty adjustment mechanism that is hard coded into Bitcoin's source code, periodically adjusts the difficulty in validating transactions on the blockchain. The difficulty adjustment attempts to keep the time between transactions to 10 minutes. As a result, the amount of energy needed to process each transaction is directly correlated to network difficulty at any given time.

Simply put, more miners equals more difficulty and less profitability. The industry tracks this prime variable based on the US dollar revenue generated per terahash (TH). In early-2018, this index was $1.61 per TH. Since then, the market value of BTC is up significantly, which has attracted more miners and pushed difficulty to all-time highs. As a consequence, the index declined to $0.076 in October 2020 and is now around $0.238.

Is Bitcoin Mining Still Profitable?

To stay ahead of the game, miners need to focus on variables they can control. Specifically, access to cheaper energy. As BTC’s popularity reaches new heights, miners with access to the cheapest energy could be the most profitable.

While cheap capital reduces financial costs, Bitcoin miners also need to focus on operational costs. The electricity needed to power server farms is the most important operational cost miners have to consider.

China had an early advantage in this arena. However, China’s dominance is gradually decreasing as mining costs increase. In recent years, miners have relocated to destinations with less regulatory uncertainty, cooler climates, and better access to sustainable and renewable energy.

Some of Argo Blockchain’s largest mining facilities are located in the Canadian province of Quebec, where much of the electricity is produced by hydroelectric power plants. Canada’s relatively cooler climate and favourable regulatory framework also make it a top destination for Bitcoin miners as the industry seeks out efficiency, both today and in the future.
