Digital currencies. As the use of cryptocurrencies expands worldwide, governments and financial institutions are seeking to establish legal frameworks to regulate the market, protect investors, and prevent illegal activities such as money laundering and terrorism financing. The discussion includes issues such as taxation, licensing of trading platforms, and anti-fraud measures. These laws directly affect prices and liquidity, and can lead to sharp fluctuations. While some believe that regulation threatens the principle of decentralization, others argue that it is necessary to make the market safer and more attractive to major institutions and new investors.
