Southwest Financial system, Second Quarter 2022
Cryptocurrencies have existed for over 10 years. Since their launch, cryptocurrencies have grown in amount and market capitalization. As a result of they depend on decentralized expertise that’s computationally complicated, cryptocurrencies are important power customers. Texas’ power-generating talents have captured the eye of cryptocurrencies as miners transfer to the state.
Cryptocurrencies have been round over a decade, with their valuations rising notably, although not all the time steadily. Cryptocurrencies are a type of digital forex that may function a medium of change and a retailer of worth, though they lack the backing of any central authority or authorities.
The market capitalization of bitcoin and ethereum—the 2 largest cryptocurrencies—totaled about $781 billion as of June 1 (Chart 1). All instructed, there are about 100 important cryptocurrencies, with a market capitalization of roughly $1.2 trillion, down 60 p.c from their latest peak in fall 2021.
Cryptocurrency mining refers back to the work (carried out by computer systems) that manages the blockchain, the report of cryptocurrency transactions. Crypto mining is controversial, partially, as a result of the method requires massive portions of electrical energy, which is commonly produced utilizing fossil fuels corresponding to pure gasoline or coal. Furthermore, crypto mining is rising rapidly within the U.S. and in Texas, following latest antagonistic regulatory and political developments in international facilities of crypto mining exercise—China, Russia and Kazakhstan.[1]
Mining exercise is measured by hash fee—a metric of the computational energy wanted for calculations to keep up the blockchain and earn new cryptocurrency cash. The bitcoin hash fee plummeted to zero in China in 2021 whereas rising within the U.S. and different international locations (Chart 2).
Though dependable knowledge are onerous to return by, some observers recommend Texas stands out as the largest state for crypto mining, accounting for 25 p.c of the U.S. whole.[2] Texas’ attraction stands out as the state’s comparatively cheap power and favorable laws.
A Digital Foreign money
Cryptocurrencies are supposed for use like another forex. However in contrast to conventional bodily currencies such because the greenback, cryptocurrencies solely exist electronically.
A person can maintain crypto as a retailer of worth, an funding, and use it as collateral or as a method of cost. Digital cash might be “mined” or bought on an change and saved in a digital pockets.
Transactions during which a cryptocurrency is used are verified and recorded in a distributed public ledger—a database that’s unfold throughout a community of computer systems—one of the best recognized of which is blockchain.
Transactions are saved in discrete blocks that taken collectively type a sequence. Every block is a set of detailed knowledge, corresponding to data or transactions. The blocks are iteratively linked in a sequence primarily based on a person block’s hash worth—a calculation primarily based on the info it holds relative to different such hyperlinks within the chain.
On this course of—which additionally serves as a safety measure—the hash worth of a earlier knowledge block determines the subsequent block’s hash worth, which is then used to find out the worth of the next block.
There are a number of causes for curiosity in cryptocurrencies. For some crypto fans, it derives from concern whether or not fiat currencies—just like the U.S. greenback and euro—are a dependable retailer of worth, particularly when the Federal Reserve and different central banks have expanded their stability sheets and put considerably extra forex in circulation following the World Monetary Disaster within the late 2000s and once more in the course of the 2020–21 pandemic.
Therefore, some traders not solely purchase and maintain cryptocurrencies as a result of they imagine they’ll enhance in worth but additionally as a result of they imagine cryptos could act as an inflation hedge, though that hasn’t been the case within the present high-inflation episode.[3] In fact, others fear that with no authorities backing, cryptocurrencies’ worth is just not secured by any central authority and will collapse.
A further enchantment of cryptocurrencies is that the blockchain permits quick encrypted transaction processing and in methods that may embody different transaction info, corresponding to contract and counterparty particulars. This appeals to many customers and avid gamers, significantly for individuals who transact throughout borders or want real-time funds.
Lastly, blockchain expertise permits for larger decentralization of finance as a result of it happens on a distributed ledger and isn’t managed by a authorities. Therefore, one other enchantment of cryptocurrency is the unregulated and nameless nature of the transactions. Nevertheless, this characteristic seemingly attracts people who search to evade taxes, money-laundering legal guidelines or capital controls.
Transaction Prices, Velocity
Cryptocurrencies can have excessive transaction prices and sluggish velocity, and so they carry the chance of manipulation. Whereas decentralized finance has the potential to cut back prices and speed up transactions (relative to conventional monetary programs), it doesn’t all the time ship.
Transaction prices are risky and may rise sharply as transaction quantity will increase. Bitcoin transaction charges had been roughly $1.30 per transaction in June 2020, rose to $13.15 by October 2020 and exceeded $60 in April 2021.[4]
A latest examine famous {that a} seemingly purpose for prime charges is an absence of competitors in cryptocurrency markets, with its authors discovering that bitcoin mining capability is extremely concentrated—the highest 10 p.c of miners management 90 p.c of mining capability. Much more telling, simply 0.1 p.c of miners account for about 50 p.c of mining capability.[5]
A brand new cost protocol dubbed “lightning” was added to bitcoin in 2018 to extend velocity and cut back transaction prices related to micropayments.[6] Lightning defers ultimate settlement on the bitcoin blockchain, although that opens a safety vulnerability that complicates tracing transactions.
Safety issues heart on assaults on the blockchain. A 2020 examine analyzed 14 assaults on 13 completely different cryptocurrencies the place the blockchain was manipulated by gaining management over 51 p.c of the mining nodes—computer systems trying to find new items of cryptocurrency—to undermine the blockchain’s integrity.[7]
Keys to Crypto Mining
Cryptocurrency mining is the time period describing the computer systems that approve blocks of transactions to turn out to be a part of the blockchain. As compensation for sustaining the blockchain, miners obtain new cryptocurrency.
For instance, the compensation for mining one block of the bitcoin blockchain is 6.25 bitcoins, about $30,000 primarily based on the change fee as of June 1, 2022.[8] Provided that there are about 144 blocks mined on daily basis, miners collectively earn bitcoin price roughly $27 million day by day.[9]
To take part, miners should remedy a sophisticated math drawback, known as the “proof of labor.” Fixing this drawback is sluggish and power intensive, requiring important quantities of computing energy, with no assure that the time and power expenditure will repay—solely the primary miner to resolve the proof of labor earns compensation.
Proof of labor is called a “consensus protocol”—a means during which consensus might be reached on modifications to a blockchain. Though the proof-of-work consensus mechanism is basically efficient at permitting decentralization, it requires important electrical energy.[10]
Critics argue that the method is wasteful; power might be directed to extra productive makes use of, corresponding to powering properties and companies.[11]
Vitality Economics
Mining and buying and selling of bitcoin consumes an estimated 91 terawatt hours yearly, equal to the annual nationwide power consumption of Finland or Jordan.[12] Mining a single block on the bitcoin blockchain consumes about 2,000 kilowatt hours, extra energy than a mean U.S. family consumes in two months.[13]
The traditionally low price of electrical energy in Texas relative to the nation and the state’s speedy development of renewable power sources, in addition to mild regulation, have seemingly helped appeal to crypto miners to the area.
What are the implications for Texas’ power sector? On the one hand, there are issues that crypto mining energy demand can enhance power prices, cut back electrical energy grid stability and result in larger carbon emissions.
Alternatively, crypto supporters say it’s attainable that co-locating cryptocurrency mining with business renewable power era might mitigate air pollution, enhance the economics of renewable tasks and appeal to traders.
This argument suggests crypto mining might be a key supply of demand for renewable energy in periods when electrical energy demand is low and energy output is excessive and storing the surplus electrical energy in batteries is impractical. Therefore, combining crypto mining with renewable tasks would supply extra constant, reliable electrical energy demand that would help renewable challenge cashflows and enhance reimbursement prospects for windfarms and photo voltaic farms, for instance.[14]
The connection between cryptocurrency and power markets suggests extra analysis concerning the markets’ relationships could also be acceptable. For instance, relying on whether or not the worth of bitcoin declines or will increase, the payout for mining diminishes or grows, assuming a relentless worth for electrical energy. This rate-of-return calculation could have an effect on the willingness of miners to take part. Miner participation determines how rapidly new bitcoin involves {the marketplace}, affecting its liquidity and worth.
Moreover, the quantity of mining exercise can also immediate extra blockchain transactions, as some miners liquidate a part of their crypto earnings to pay for the prices of mining.
The rise in demand for power attributable to cryptocurrency mining is contingent on the continued use of the proof-of-work consensus protocol. The problem of mining new blocks on a proof-of-work blockchain will increase because the variety of miners rises. As issues surrounding the power price for proof of labor have grown, some cryptocurrencies could evolve to much less energy-intensive consensus protocols.
Ethereum, the second-largest cryptocurrency, introduced plans to transform from proof of labor to proof of stake in late 2022. In proof-of-stake protocols, that are much less power intensive, miners function a validator in proportion to the quantity of the cryptocurrency they management.
Influence on Banks
Texas affirmed in June 2021 that state-chartered banks could provide custody providers for digital forex property. [15] The state has additionally stated banks can permit digital currencies as collateral for loans.[16] State officers additionally look like responding to the safety challenges of “bodily” holding crypto, potential working difficulties at established crypto exchanges and a want to supply conventional monetary establishments an entrée to offering crypto custody and associated providers.[17]
Banks looking for to supply crypto providers should conduct an evaluation—figuring out and implementing controls to mitigate dangers, together with lack of consumer crypto property, risk-monitoring capability, money-laundering issues and reputational threat.
Nonetheless, cryptocurrencies stay a novel growth within the monetary providers ecosystem. As such, they could signify elevated threat to the monetary sector whereas concurrently providing innovation that holds the potential for long-term change.[18]

- China’s central financial institution banned all cryptocurrency transactions In September 2021; the Russian central financial institution proposed banning cryptocurrency in January 2022. Whereas this proposal was pending, the U.S. and European Union took measures in April to sanction Russian entities energetic in cryptocurrency in mild of Russia’s conflict in opposition to Ukraine. In Kazakhstan, home power shortages resulted in a authorities crackdown on greater than 100 unlicensed crypto mining operations.
