ANALISIS BIBLIOMETRIK PERAN CRYPTOCURRENCY DALAM MENDUKUNG INVESTMENT SUSTAINABILITY (2015–2025)

Abstract

The global shift toward sustainable investment and ESG integration has reshaped modern financial systems, encouraging the exploration of digital financial innovations that align economic performance with environmental responsibility. Among these innovations, cryptocurrency and blockchain technology have gained substantial academic attention due to their potential to enhance transparency, efficiency, and financial inclusion. However, the sustainability of cryptocurrency remains highly debated, particularly concerning energy consumption, carbon emissions, and regulatory implications. Despite the rapid growth of related publications, existing studies remain fragmented across themes such as green finance, environmental impact, decentralized finance, and digital asset governance, with limited comprehensive mapping of the field. This study aims to analyze the development, intellectual structure, and thematic evolution of global research on the role of cryptocurrency in supporting investment sustainability during the period 2015–2025. A quantitative descriptive approach using bibliometric analysis was employed. Data were collected from the Scopus database, resulting in 429 peer-reviewed journal articles selected through a systematic keyword strategy. Bibliometrix (R) was used to examine publication trends, influential contributors, and citation patterns, while VOSviewer was utilized to visualize keyword co-occurrence networks and thematic clusters. The findings indicate a significant increase in scholarly attention after 2019, reflecting growing concerns regarding sustainable digital finance and environmental accountability. Network analysis identifies sustainability, blockchain, ESG, green finance, energy consumption, and regulatory frameworks as dominant research clusters. Overlay visualization demonstrates a temporal shift from early conceptual discussions on digital currencies toward applied research focusing on environmental impacts, low-energy consensus mechanisms, and sustainable crypto investment strategies. Several emerging themes remain underexplored, offering strategic directions for future research.
