Cryptocurrencies stand out for their security, decentralization, and global accessibility. Based on blockchain technology, they offer secure, transparent, and immutable transactions, reducing the risk of fraud. Because they are decentralized, they are not subject to control by governments or financial institutions, which gives users greater autonomy. In addition, they allow for fast, low-cost transactions, especially in international transactions, eliminating intermediaries and high fees. Another advantage is financial inclusion, as they allow access to the financial system for people without bank accounts. Cryptocurrencies also offer privacy and data protection, respecting the identity of users. Finally, they are seen as a way to diversify investments, attracting more and more followers looking for innovation and economic freedom.
