Cryptocurrencies are digital money that people can use to buy goods and services. What makes them different from other currencies is that they don’t rely on a central authority, like a government or a bank, to control them. Instead, they use blockchain technology to keep track of transactions and ensure that everything is secure. One of the benefits of cryptocurrencies is that they are transparent, which means that anyone can see what’s happening with them. This can potentially change how we think about money and how we use it.
