What’s Bitcoin Mining? How It Works and How It Pays | North American bitcoin mining is growing despite price volatility and environmental concerns. Miners have fled to Texas since 2021. The ban, which reportedly reduced China’s control of Bitcoin mining from two-thirds of the global industry in April 2021 to zero in July 2021, has given North American companies, particularly energy companies, a new opportunity to learn about Bitcoin mining and incorporate it into their business models.
Miners verify blockchain transactions. The cryptocurrency’s blockchain network is growing in a cryptography race. In November 2021, Bitcoin (BTC) reached $68,000 for winning miners.
Riot Blockchain and Marathon Digital Holdings are raising unprecedented amounts of funding to develop manufacturing and industrial-scale activities after the Chinese ban. Chinese corporations have joined the Great Mining Migration to North America, investing in US infrastructure and establishing vast warehouses with hundreds of little computers to mine Bitcoin.
My feasibility studies for Canadian clients exploring this developing industry show that new players, particularly energy companies, are joining through joint ventures and other partnerships. Cryptocurrency mining is power-intensive. That means North American companies with reliable, low-cost electricity—especially from renewable sources—can alter the sector.

Bitcoin is exploding.
Bitcoin has inspired many cryptocurrencies since 2009, but its value is unrivaled. Despite its volatility, mining 21 million Bitcoins on a set basis stabilizes its price. Despite approximately 19 million in circulation, Bitcoin production will last until 2140 because mining rewards are periodically halved.
No crypto network has reached Bitcoin’s popularity in supply management. Investors adopted bitcoin futures and exchange-traded funds early on in regulated US and European markets. Tesla and Overstock’s financials showed it. Demand propelled Bitcoin’s market cap above $1 trillion in November 2021. Ethereum, the second-most-popular cryptocurrency, reached about half that value.
Bitcoin mining farms are remarkable. Genesis Mining, Iceland’s largest and most advanced Bitcoin mining facility, utilizes more electricity than any other Icelandic business. Riot Blockchain’s 100-acre Texas farm includes 60,000 Bitcoin-only mining processors in three massive warehouses.
The Basics of Bitcoin Mining
Most cryptocurrencies, including Bitcoin, require miners to be the first to predict a hash value equal to or lower than Bitcoin’s transaction hash. As more miners compete and more computer power is deployed, each miner’s chance of coming in first is reduced—currently one in the tens of trillions—helping maintain a pace of one block every 10 minutes.
Bitcoin uses PoW for consensus. This method is especially secure and decentralized because it uses thousands of computers. It has downsides. It’s quite energy-intensive. Crypto mining requires more electricity to earn cryptocurrency and maintain the network as computer power is needed.
Finally, Bitcoin’s supply management system will reduce the reward for mining a block from 6.25 BTC in May 2020 to 3.125 BTC in 2024. Even with that expected reduction, mining bullishness shows the industry’s profitability and the hope that the original coin would keep gaining. When Chinese operators were forced to close in 2021, the network’s hash rate, which represents the total number of hash guesses being computed, dropped. New miners benefited greatly. The December 2021 hash rate was 175 quintillion hashes (EH/s).
Setup for Bitcoin Mining
Bitcoin mining requires:
- At least one ASIC miner, a computer intended to mine a certain coin.
- Affordable, reliable energy.
- Reliable internet.
- A cooling system (for home or Bitcoin farm mining).
- Computer, software, and technical skill to set up and oversee operations.
- A computer and several ASIC miners can make a home mining enterprise.
If they win a block, Bitcoin miners receive a transaction fee and the block reward. My estimate shows that by the end of 2021, transaction fees averaged 0.125 BTC, or 2% of the block reward, depending on network conditions and how much the transactor is prepared to pay for accelerated processing.
Risks of Bitcoin Mining
No new venture is risk-free. Miners are paid in Bitcoin, therefore price fluctuation is a huge income risk. Operating risks include internet connectivity issues, overheating ASICs, and system hacks—though the Bitcoin network’s size and security make hacking risk low.
Cryptocurrencies have also responded. Many large producers are buying renewable energy directly or buying carbon credits. Great American Mining and Crusoe Energy have also found ways for mining farms to use flaring natural gas at oil fields, surplus solar or wind power that can’t be stored, and dam overflow hydropower. Crypto mining must not boost demand for this technique to work.
Bitcoin Mining: New Opportunity
Scaled Bitcoin mining economics are appealing, but manufacturers must consider regulatory and environmental factors. New entrants like power firms can use Bitcoin mining to better manage energy output and harness public opinion.
According to the University of Cambridge, 40% of PoW mining is powered by renewable energy. Eco-friendly energy companies may help and profit.
