His interest extends to further aspects of the technology, ranging from environmental implications to data analytics applications. She is specialized in energy markets and accounting.
Her research focuses on carbon accounting in the corporate and cryptocurrency space. She has previously analyzed blockchain-related firms for a venture capital fund.
His research focuses on the implications of climate change from an economic point of view. Bitcoin is a digital currency based on a cryptographically secured distributed ledger and represents the first and best-known blockchain application.
Depending on the methodology and assumptions, energy consumption estimates chart a wide range of results as depicted in Figure 1. The methodologies of the estimates have become more sophisticated over time, and yet, most studies have focused exclusively on Bitcoin and thereby ignored that more than further mineable coins and tokens exist. Energy consumption is presented in gigawatt GW. Details on the underlying methodologies and date sources can be found in the Supplemental Information and Table S1.
To estimate the energy consumption of cryptocurrencies beyond Bitcoin, we resort to a methodology proposed by Krause and Tolaymat 2 that employs hash rates of cryptocurrency networks and suitable mining devices. These top 20 use 13 different proof-of-work algorithms. Bitcoin, for instance, uses the SHA algorithm that allows for mining with highly specialized, ASIC-based devices, which are considerably more energy efficient than conventional graphic processing units GPUs.
Dividing the network hash rates by efficiencies of mining devices yields the rated power of each network. The table displays the top 20 mineable currencies with their respective algorithms, efficiencies of suitable mining devices, and rated power of the networks.
It is important to note that currencies with ASIC-resistant algorithms consume an overproportionate amount of energy in relation to their market capitalization.
As listed in Table 1 , RavenCoin, for instance, accounts for 4. After a few days, the hash rate bounced back to half of the pre-update level as miners switched from ASIC to less-energy-efficient GPUs. In absolute terms, the total energy consumption estimate in Figure 1 appears rather conservative. Alternative estimation methods including, e. The CBECI uses a bottom-up approach, whereas Digiconomist applies a top-down approach which has been criticized for potential overestimating in the past 6.
Given that we consistently apply the bottom-up approach of Krause and Tolaymat 2 to all 20 currencies, potentially higher absolute numbers would not impair the relative shares if we assume the neglected factors apply to all currencies equally. Nonetheless, all energy estimates and underlying assumptions are subject to uncertainty.
In particular, the selections and operation of the mining devices pose a significant challenge given that the mining industry operates secretively. Miners may shut down and ramp up certain devices temporarily as a response to variations in electricity prices and market prices i.
Energy consumption, per se, is not an issue in the context of climate change. For instance, clean generation resources, such as wind and solar, produce energy without emitting greenhouse gases GHG which trap heat in the atmosphere and cause cost—now and for future generations.
Fossil generation resources—most prominently coal and gas—cause such GHG emissions. Consequently, the emission factor of electricity depends on the constitution of the generation resource mix, which varies among countries as well as regions. The relative energy demand of cryptocurrencies in Table 1 could be used to roughly estimate GHG emissions.
To derive a profound estimate of caused GHG emissions, however, more research is needed into currency-specific factors such as the respective footprint of mining operations.
Translating energy consumption into GHG emissions adds further uncertainty. Krause and Tolaymat, 2 for instance, use average emission factors of electricity consumption in several countries to chart a range of potential results, which vary by a factor of over 4 between the lowest and highest values. As miners seek locations with low electricity prices, other studies assume high shares of cheap renewable energy, which results in much lower emissions estimates. Mining operations cause an additional load that activates additional generation resources.
The increase in full-load hours of certain generation resources may lead to fuel switching effects and alter local emission intensities. We show in this Commentary the necessity to broaden the debate on the environmental impacts of cryptocurrencies—beyond Bitcoin. Irrespective of the uncertainty in assessing the energy demand and associated GHG emissions of cryptocurrencies, our estimate for understudied currencies underlines the importance of including these in the debate.
Going forward, a holistic understanding of the environmental impacts may also help policymakers to set the right rules for cryptocurrencies and blockchain applications in general.
Most academic studies have been focusing not only exclusively on Bitcoin but also primarily on externalities resulting from the energy consumption during the mining process. Although the use phase predominantly contributes to the carbon footprint of conventional data centers, 11 this might not apply to cryptocurrencies given the high price volatility and technological changes.
Translating the total energy consumption into carbon emissions, and including embedded emissions of mining device production as well as e-waste, 12 would further complement the picture and reveal the total environmental damage caused by cryptocurrencies. The insights from cryptocurrencies may also be applied to novel blockchain applications that are rapidly maturing.
In the energy sector, for instance, an increasing number of blockchain use cases have emerged, ranging from peer-to-peer energy trading to the management of carbon emissions to mitigate climate change.

5 Best Cryptocurrencies to Invest in 2020
This paper examines the risk connectedness across seven cryptocurrencies, Bitcoin, Ethereum, Ripple, Litecoin, Stellar, Monero, and Dash, which have large capitalizations in the cryptocurrency market. The data sample is from August 7, , to February 15, We measure the return risks of the cryptocurrencies by using the CAViaR model, showing that they have similar risk tendencies, with volatility clusterings from the beginning of to the end of The net pairwise spillover index developed by Diebold and Yilmaz [ 1 ] is used as the measure of the risk connectedness among the cryptocurrencies. We find that the risk spillover directions are highly correlative with the market capitalizations of the cryptocurrencies.
5 Best New Cryptocurrencies To Buy in 2022
Over the past few years, the cryptocurrency market, which is still in its early stages, has gained a lot of momentum and has been drawing several young Indian investors' attention towards it. These days retail and institutional investors are keen to invest in digital currency for both - long-term and short-term - profits. Undoubtedly, cryptos like Bitcoin, Ethereum blockchain are among the popular cryptocurrencies of which most people are aware. Young investors, who are willing to invest in the crypto industry, are confused about where to invest. However, just like the stock market, profit and loss are also part of the crypto industry and are subject to market risk. Coins and tokens with rock hard fundamentals are still promising for further growth. Bitcoin, Ethereum, Cardano, etc have already become the most worthy candidates of the Crypto industry," he said. He said that the Crypto space and alt investment sector are no longer oblivious to investors but has evolved into long mature market. Not just an haven for tech developers and nerds, even the institutional giants and traditional investors have started to put their trust and have amplified acceptance.

For crypto startups and unicorns, was an exceptionally good year. But for public companies tied to the crypto space, has been off to a bad start. And the bulk of shares from a sample of public companies in the crypto space, most previously venture-backed, all were down over 50 percent from peaks hit in the past year. Meanwhile, in the private markets the frenzy around funding for crypto- and blockchain-focused companies continues.
