Cryptocurrencies are digital and intangible forms of currency, meaning that they cannot be touched or felt but still hold a certain value. These cryptocurrencies, or crypto for short, come in a variety of forms and serve different purposes, much like how different countries have their own national currencies with varying designs and values.

- The process of cryptography is used to make financial transactions on the blockchain secure.
