Cryptocurrency is a type of digital money that uses blockchain technology to work. Cryptocurrencies run on decentralised networks where computers all over the world check transactions. This is different from traditional currencies that are issued by governments. In the last ten years, crypto has gone from being a niche technology to a global financial movement that draws in investors, businesses, and governments.
Cryptocurrency is seen by many as the future of money since it lets consumers make safe, quick, and borderless transactions without needing banks or other middlemen.
