Sustainable Digital Assets: A Study on Attitudes of Millennial and Gen-Z Investors in the State of West Bengal, India, Towards Investment in Green Cryptocurrencies

In an era defined by the twin forces of digital transformation and environmental urgency, the global financial landscape stands at a pivotal crossroads. Technology- driven innovation has disrupted traditional models of value creation and exchange, while the imperatives of sustainability have challenged investors, policymakers, and corporations alike to reimagine growth in ethical and ecological terms. It is within this complex intersection that the present work — Sustainable Digital Assets: A Study on Attitudes of Millennial and Gen-Z Investors in the State of West Bengal, India, Towards Investment in Green Cryptocurrencies — situates itself. The study represents a confluence of behavioural finance, environmental economics, and digital technology, attempting to interpret how the youngest cohorts of investors are responding to the moral and material questions posed by the rise of sustainable cryptocurrencies.

The twenty-first century has witnessed the emergence of digital assets as a transformative force in global finance. From the advent of Bitcoin in 2009 to the proliferation of blockchain-enabled innovations today, the trajectory of financial evolution has been marked by decentralization, transparency, and unprecedented accessibility. Yet, this revolution has not been without its contradictions. The environmental cost of crypto-mining, largely dependent on energy-intensive proof-of- work mechanisms, has generated significant concern among ecologists, regulators, and socially responsible investors. Simultaneously, a new category of eco-friendly cryptocurrencies — often termed green cryptocurrencies — has emerged, seeking to reconcile the technological potential of digital assets with the imperatives of sustainability. This book explores how young investors, particularly Millennials and Generation Z in the Indian state of West Bengal, perceive and engage with this emerging asset class.

The genesis of this research lay in a set of broader questions concerning the sustainability of the digital economy. Can speculative technologies be aligned with long-term environmental goals? How do ethical considerations coexist with behavioral biases in investment decision-making? And, most importantly, how are new generations of investors redefining the relationship between profit and purpose in a world that is rapidly digitizing yet environmentally constrained? These questions assumed greater relevance in the aftermath of global crises — economic, ecological, and social — that have forced both individuals and institutions to revisit the moral foundations of finance.

India, as one of the world’s fastest-growing digital economies, provides an illuminating context for such an inquiry. With nearly half of its population comprising Millennials and Generation Z, India represents not only a vast market for digital assets but also a social laboratory for studying the interaction between technology adoption, environmental awareness, and investment behaviour. West Bengal, a state marked by intellectual vibrancy and a rapidly urbanizing youth demographic, offered a particularly rich ground for this empirical investigation. The study, while regional in scope, aspires to speak to global themes — the psychology of digital finance, the ethics of environmental stewardship, and the evolving contours of sustainable capitalism.

The book draws upon a robust methodological framework combining Covariance- Based Structural Equation Modelling (CB-SEM) and Partial Least Squares Structural Equation Modelling (PLS-SEM). By employing a large and statistically significant sample, it captures the subtle dynamics that influence investment attitudes toward green cryptocurrencies. Central to this framework is the Dual Mandate hypothesis: that the motivation to invest in green digital assets arises from both an ethical impulse — reflected in the concern for environmental sustainability — and a speculative impulse, manifest in social and psychological drivers such as the fear of missing out (FOMO) and herd behaviour. These twin forces, as the study demonstrates, coexist and interact in complex ways, giving rise to a new investment archetype — one that is both idealistic and opportunistic, digital and conscientious.

Beyond the realm of empirical modelling, the book also engages with the philosophical and policy dimensions of sustainable finance. It argues that the future of digital assets will depend on their ability to align with the broader agenda of sustainable development. The decarbonization of blockchain technologies, the integration of cryptocurrencies with carbon-credit mechanisms, and the creation of regulatory frameworks that reward ethical investment behaviour are all crucial to achieving this alignment. The study therefore proposes a Four-Pillar Policy Framework — encompassing ideological alignment, behavioural management, regulatory incentives, and investor protection — to guide the responsible evolution of the green cryptocurrency ecosystem.
 
At a theoretical level, the work extends the boundaries of behavioural finance by incorporating sustainability as an intrinsic cognitive and emotional variable influencing investor behaviour. Traditionally, models of investment psychology have focused on biases such as overconfidence, herd mentality, or loss aversion. However, as the data in this research reveal, environmental consciousness itself functions as a behavioural determinant — shaping intention, mediating speculative drives, and ultimately influencing real investment decisions. This reframing of behavioural finance through the lens of environmental ethics represents one of the distinctive contributions of the study to the academic literature.

The research journey that culminated in this book was as intellectually demanding as it was personally transformative. Conducting empirical research on a subject as fluid and volatile as cryptocurrency investment required constant adaptation to new data, shifting market dynamics, and evolving regulatory discourses. Moreover, understanding the motivations of Millennials and Gen Z investors demanded both quantitative rigour and qualitative sensitivity — an appreciation of not only statistical patterns but also generational narratives of aspiration, risk, and responsibility. Throughout this journey, the integration of diverse disciplines — finance, psychology, environmental science, and information technology — remained a defining feature of the research process.

For a global readership, this book offers both regional insight and universal relevance. Although the empirical focus lies on West Bengal, the behavioural tendencies observed among young investors resonate with patterns emerging across the world. The dual pursuit of ethical alignment and financial opportunity is a hallmark of the global youth investment psyche. Whether in Silicon Valley, Singapore, or Kolkata, young investors increasingly view their financial choices as expressions of identity, ideology, and digital fluency. The rise of sustainable cryptocurrencies thus symbolizes a generational shift from the extractive capitalism of the past to a regenerative capitalism of the future — one that seeks to balance profit with planetary responsibility.

The book is structured to provide a coherent progression from conceptual foundations to empirical validation and policy synthesis. The initial chapters trace the historical evolution of investment behaviour, highlighting how technological disruption has continuously reshaped the contours of financial participation. Subsequent sections examine the theoretical underpinnings of sustainable finance and behavioural decision-making, leading to the development of a comprehensive conceptual model tested through Structural Equation Modelling. The empirical findings are followed by an interpretive analysis that situates these results within broader economic, technological, and ethical debates. Finally, the book concludes with strategic recommendations for policymakers, regulators, and investors seeking to foster a sustainable digital asset ecosystem.

While this work is anchored in academic scholarship, its implications extend far beyond the university. For policymakers, it offers empirical evidence to design nuanced regulatory frameworks that encourage innovation without compromising environmental integrity. For financial institutions and fintech entrepreneurs, it provides insight into the evolving preferences of young investors — a demographic that will soon dominate global capital flows. For scholars, it opens new avenues for interdisciplinary research at the intersection of behavioural finance, digital technology, and sustainability. And for the general reader, it offers a reflective exploration of how human values and aspirations continue to shape, and be shaped by, the relentless advance of digital modernity.

As the global community grapples with the twin challenges of economic uncertainty and ecological degradation, the need to reconcile finance with sustainability has never been more urgent. Green cryptocurrencies, though nascent, represent one of the most intriguing experiments in this quest. Whether they succeed in transforming global finance or remain a niche phenomenon will depend not merely on technological innovation but on the attitudes and decisions of investors themselves — particularly those of the younger generations who will inherit the digital and ecological future. It is to that evolving dialogue between technology, ethics, and human behaviour that this book humbly seeks to contribute.

The journey of Sustainable Digital Assets is thus not merely a study of market behaviour but a reflection on the moral imagination of a new age of investors. It is an invitation to scholars, practitioners, and citizens alike to envision finance not as a detached instrument of accumulation but as a participatory practice of stewardship — of both wealth and the world we share.
