The unprecedented growth of the cryptocurrency market over the past decade has attracted significant interest from various stakeholders, including investors, policymakers, and researchers. Cryptocurrencies, digital currencies that operate on blockchain technology, are revolutionary because they offer financial transactions without the need for traditional banking systems. This innovative approach to finance has reshaped the global economic landscape, presenting unique opportunities and substantial challenges. Cryptocurrency, spearheaded by the introduction of Bitcoin in 2008 by the pseudonymous Satoshi Nakamoto, represents a significant shift from traditional fiat currencies to a decentralized digital economy. Bitcoin and its contemporaries rely on a peer-to-peer network, utilizing cryptographic techniques to ensure transaction security and user anonymity, a characteristic has fueled both adoption and controversy. As the market has grown, so have the complexities associated with its expansion, notably in regulation, security, and market dynamics. This dissertation explores these complexities through three distinct but interconnected essays, each focusing on a different aspect of the cryptocurrency environment.
