A Fuzzy SIWEC Methodology for Evaluating the Challenges of Cryptocurrencies in Developing Countries

Abstract

This study applies a fuzzy simple weight calculation (F-SIWEC) method to systematically assess the challenges of cryptocurrencies in Africa. Data was collected from four domain experts who evaluated six challenges, and the adopted method was then applied to determine the relative importance of each challenge. The findings indicate that market volatility and regulatory uncertainty are the top two critical challenges to cryptocurrencies. Meanwhile, tax considerations and environmental concerns are the least critical challenges. The study makes a meaningful contribution to the decision sciences and management literature by offering practical insights for policymakers and concludes by outlining clear avenues for future research.
