Bitcoin is an innovative and controversial digital currency. From a technical perspective, it is based on blockchain technology, characterized by decentralization and immutability, bringing new ideas and possibilities to the financial sector. However, from an investment standpoint, its price is highly volatile, lacks effective regulation, and is prone to speculation and illegal activities such as money laundering and smuggling. Furthermore, the process of 'mining' Bitcoin consumes a large amount of energy, placing significant pressure on the environment. Therefore, Bitcoin should be viewed objectively, recognizing both its technological innovations and the various risks and issues it brings.
