What Is Cryptocurrency?
Cryptocurrency is a form of virtual currency built on cryptographic technology, designed for secure digital transactions. It operates independently of traditional financial systems, meaning it’s not managed by banks or overseen by government bodies. This decentralized nature, paired with blockchain technology, ensures transparency, speed, and global accessibility.
After the launch of Bitcoin in 2009, the digital asset landscape has grown significantly, introducing thousands of other cryptocurrencies tailored to various industries—ranging from finance and gaming to art and decentralized services.
