How Much Does it Cost to Mine a Bitcoin? $20K with 4.7c/Kwh
Mining a Bitcoin depends on your energy rate per Kwh, it costs $11,000K to mine a Bitcoin at 10 cents per Kwh and $5,170K to mine a Bitcoin at 4.7 cents per Kwh. Learn how and if mining right for you in July 2024!
As Bitcoin’s price goes up, so do the miners' prices. Depending on what your energy costs are per kilowatt hour as well as market conditions, it may be more beneficial to mine; other times, it may be better to simply purchase Bitcoin outright.
In this article we break down the essential costs and considerations involved in mining Bitcoin.
Bitcoin mining is the process by which computers secure the network, process transactions, and unlock the newly issued Bitcoin. Specialized computers expend energy in a race to solve a cryptographic puzzle.
Whoever wins the race wins the ability to add the next block of data into Bitcoin’s chain of transaction history. That miner also earns the newly issued Bitcoin and the transaction fees for that particular block.
When deciding whether to mine or not, a few factors must be considered. Mining allows you to essentially purchase Bitcoin at the cost of energy rather than market prices.
It can be extremely lucrative to enter the market before large, upward price movements. However, if energy costs are too high, it may not be profitable to mine rather than buy Bitcoin.
Another factor is hash rate growth. As more miners join the network to provide computing power, your existing computing power is diluted gradually. Generally speaking, mining rigs will produce Bitcoin at a decreasing rate, becoming less profitable over time.
#1 What is Bitcoin, and why does it need to be mined?
Bitcoin is a network, asset, and protocol that allows for the transfer of value across the internet in a peer-to-peer way without the need for an intermediary. Imagine sending your friends cash through an email.
This is done in a verifiable way that cannot be counterfeited or double-spent, so you always know the Bitcoin you hold is real and legitimate.
Bitcoin mining started as a way for fair issuance. All people needed to do was run free, open-source software on their computers to earn Bitcoin as a reward. Miners also process transactions.
Swan’s Yan Pritzker breaks down Bitcoin mining as a lottery system in this great Twitter thread:
Miners earn the newly minted Bitcoin and transaction fees by using electricity to solve a cryptographic puzzle called 'proof of work.'
As network power grew, specialized computers were developed to make mining more efficient. They now serve as a digital security fence that keeps the network honest and secure.
In exchange, miners receive newly issued Bitcoin and transaction fees. This is called the block reward. The block reward is currently 6.25 Bitcoin was cut in half on April 20th, 2024 to 3.125 Bitcoin.
This is known as the 'Bitcoin Halving' and is one of the mechanisms widely believed to precipitate Bitcoin bull markets and large price predictions from institutional investors.
The block reward halving happens roughly every 4 years or 210,000 blocks. It is the mechanism by which Bitcoin’s 21,000,000 (or 2.1 quadtrillion satoshis) hard cap is reached and is widely believed to precipitate bull markets.
#2 How long does it take?
New Bitcoin is created, on average, every 10 minutes as a block is created. As computers worldwide race to solve a cryptographic puzzle, they are simultaneously arranging transactions into a block of data.
This block is added to the history of all Bitcoin transactions. As a reward, the miner who solves the problem first receives the 6.25 Bitcoin and transaction fees associated with that block.
Theoretically, a miner could go forever without ever winning the race. To reduce this risk, miners will pool their computing power together to solve the problem collectively.
#3 What is a mining pool?
Mining pools are groups of miners that work together to solve the cryptographic puzzle. The more computing power they have, the higher the probability they will solve the next block.
In doing so, they earn the reward and fees, splitting the payout proportionally based on how much computing power each entity provides for the pool.
In this setup, miners opt out of the chance of winning the entire reward for themselves but, in exchange, receive more predictable income from their proof of work computations.
#4 How much does it cost?
It depends on your power cost and what type of machine you use. If you plug in the latest mining computers into your home, it will be quite expensive to mine.
To calculate the cost of mining one Bitcoin, we need to consider several factors, including the efficiency of the mining hardware (measured in watts per terahash), the hash rate of the mining operation (terahashes per second), and the total energy consumed over the period it takes to mine one Bitcoin.
However, one of the most straightforward methods is to use the average energy consumption required to mine one Bitcoin and then calculate the cost based on the electricity rate. This is what the formula looks like:
At 10 cents per kWh:
Cost = 110,000 kWh × 0.10 $ per kWh
At 4.7 cents per kWh:
Cost = 110,000 kWh × 0.047 $ per kWh
To mine one Bitcoin, the cost at 10 cents per kWh is approximately $11,000, and at 4.7 cents per kWh, it’s around $5,170.
#5 How does hash rate affect my miner?
As more computing power, or hash rate, joins the Bitcoin network, the mining algorithm difficulty will automatically rise to maintain the 10-minute target average block time.
As the difficulty rises, the marginal contribution of every computer on the network goes down, making them less profitable. Mining hash rate and difficulty have risen consistently, meaning miners slowly become less profitable over time. There are still trade-offs, however.
Newer, more efficient machines will cost substantially more than older machines. Depending on the circumstances, older machines may actually have a better return on investment and a shorter payback period.
#6 Should I mine or buy Bitcoin?
Mining Bitcoin allows you to accumulate Bitcoin at the cost of energy rather than the cost of Bitcoin and supports network security.
Many call it the native way to have recurring buys. However, there are two primary risks to consider:
If Bitcoin’s price drops too low, your miner may not produce enough Bitcoin to offset electricity costs.
The hash rate could also grow faster than expected, diluting your miner’s individual hash power and reducing return on investment.
Some may choose to mine at home, however, if they want to accumulate KYC-free Bitcoin, even if the cost of electricity exceeds the value of Bitcoin produced.
Swan Bitcoin HashRateUp Series
Everyone’s situation is different, but these are a few factors you should consider before diving in. Navigating the costs of Bitcoin mining can be quite the expedition. But don’t let the complexities of mining overshadow the simpler pathways to Bitcoin ownership.
HashrateUp is a podcast that delves into Bitcoin mining and exciting projects, utilizing hashrate production to unlock new potentials in the broader energy industry.
In this episode of HashrateUp, Jesse sits down with Adam Swick, the Chief Growth Officer at Marathon Digital Holdings, to discuss their exciting new venture into Kenya. They delved into the strategic shift in Bitcoin mining from being mere customers of power to becoming partners in solving energy problems. Adam highlights how Marathon is leveraging this approach to address issues like grid balancing and utilizing stranded or excess energy, which is particularly relevant in regions like Africa.
At Pacific Bitcoin 2023, Kaz Bycko hosted a panel with Zack Bomsta and Michael Schmid all about the world of home mining, how it can be fun, profitable and how it’s actually important for the radical decentralization of Bitcoin.
Swan is currently mining over 7 EH/s. Equal to about 1% of the entire Bitcoin network. Start your Bitcoin journey. Whether you’re new to Bitcoin or a seasoned enthusiast looking to expand your portfolio with a Bitcoin IRA.
