The case against Bitcoin is grounded in several critical concerns that challenge its viability as a sustainable and secure asset. One of the most significant issues is its environmental impact. Bitcoin's proof-of-work mechanism requires immense computational power, leading to substantial energy consumption that has raised alarms about its carbon footprint. Additionally, Bitcoin's extreme price volatility presents considerable risks for investors, making it an unreliable store of value or medium of exchange. Regulatory challenges further complicate its future, as governments worldwide grapple with how to regulate or even ban cryptocurrencies, creating an uncertain legal environment.
