Cambridge Benchmarking Study Maps the Global Cryptocurrency Mining Landscape in Unprecedented Detail

The Hardware/Software Landscape

On April 8, 2017, the Cambridge Centre for Alternative Finance released its landmark Global Cryptocurrency Benchmarking Study, a 114-page report authored by Michel Rauchs and Garrick Hileman that presents the first comprehensive empirical analysis of the cryptocurrency industry. The study draws on non-public data gathered from nearly 150 cryptocurrency companies and individual operators across 38 countries, covering four key industry sectors: exchanges, wallets, payments, and mining.

At the time of publication, Bitcoin trades at approximately $1,188 with a market capitalization of $19.3 billion, while Ethereum sits at $43.27 with a $3.9 billion market cap, according to CoinMarketCap data from April 9, 2017. The broader cryptocurrency market is experiencing a period of renewed interest and capital inflows, making the study timing particularly relevant for understanding the infrastructure powering this rapidly expanding ecosystem.

Hashrate and Difficulty

The Cambridge study provides one of the first authoritative glimpses into global cryptocurrency mining distribution by country, a data point that has remained largely opaque to researchers and policymakers alike. The researchers find that mining operations are concentrated in regions with access to cheap electricity and favorable regulatory environments, with China dominating the hashrate landscape in early 2017. Bitcoin mining difficulty continues its steady upward trajectory as more efficient ASIC hardware comes online, particularly Bitmains Antminer series which is rapidly displacing GPU-based mining operations.

The study estimates that between 5.8 million and 11.5 million cryptocurrency wallets are actively in use globally, with transaction volume from users of the largest wallets generally ranging between 10% and 25% of total Bitcoin transaction volume. These figures underscore the growing but still concentrated nature of cryptocurrency adoption, where a relatively small number of active users account for a disproportionate share of on-chain activity.

Profitability Metrics

For mining operators, the early months of 2017 represent a transitional period. With Bitcoin prices recovering from a prolonged bear market that saw prices dip below $1,000 in late 2016 and early 2017, mining profitability is improving but remains tight for operators without access to industrial-scale electricity rates. The Cambridge report highlights that mining companies surveyed report significant variation in operational costs, with electricity expenses constituting the single largest cost driver for most operations.

The study also documents the growing professionalization of the mining sector. Whereas Bitcoin mining was once the domain of hobbyists running GPUs from their homes, by early 2017 the industry is increasingly characterized by large-scale commercial operations housed in dedicated facilities, particularly in Chinas interior provinces where hydroelectric power offers cost advantages. This shift has significant implications for the networks decentralization narrative and for smaller miners who find themselves priced out of the market.

Environmental Impact

While the Cambridge study does not focus exclusively on energy consumption, its detailed mapping of mining operations by geography provides the raw data needed for subsequent analyses of cryptocurrency mining environmental footprint. The concentration of mining in regions powered by coal-based electricity has already begun to attract scrutiny from environmental groups, even as operators in hydroelectric-rich areas argue that their operations utilize otherwise curtailed renewable energy.

The studys findings on security and compliance practices at cryptocurrency companies also reveal an industry that is maturing rapidly but still grappling with growing pains. Mining operations, in particular, face challenges around regulatory clarity, with different jurisdictions applying vastly different frameworks to what is essentially a borderless activity.

Strategic Outlook

The release of the Cambridge Global Cryptocurrency Benchmarking Study marks a watershed moment for the cryptocurrency industry. For the first time, researchers, investors, and policymakers have access to rigorous, empirically grounded data about the scale and structure of the cryptocurrency ecosystem, moving the conversation beyond anecdote and speculation.

For mining operators, the study confirms what many already suspect: the industry is consolidating around professional operations with access to cheap power and cutting-edge hardware. For investors, the data on active wallet counts and transaction volumes provides valuable context for assessing the true level of cryptocurrency adoption. And for regulators, the detailed geographic mapping of mining activity offers a starting point for evidence-based policymaking.

The Cambridge team has committed to updating the benchmarking study on an annual basis, which promises to create an invaluable longitudinal dataset tracking the cryptocurrency industry evolution. As Bitcoin and the broader cryptocurrency market continue to gain mainstream attention in 2017, the availability of credible industry data could not come at a more critical time.
