Cryptocurrencies are a type of digital medium of exchange that have recently generated considerable discussion due to their price. Also called cryptocurrencies or crypto assets, they function like a currency. However, they are entirely digital, using cryptographic methods to secure financial transactions, control the creation of new units, and verify asset transfers. The first cryptocurrency was Bitcoin, created by Satoshi Nakamoto, who published an article in 2009 describing a P2P payment system he called Bitcoin. Following this, the creator released the first version of the software that manages the currency\'s network. The value of each cryptocurrency is variable, and recently there has been speculation similar to that of stock market assets. How they work The cryptocurrency system is based on a decentralized computer network, meaning that these computers are distributed around the world. The second concept is that of miners, people who are part of the nodes, and who are incentivized because each time new Bitcoins are generated, they are distributed among the members of these nodes. Over time, more cryptocurrencies with diverse characteristics have been created. Some have been establishing themselves for years as robust and popular alternatives, such as Ethereum, Litecoin, and others like them. Dogecoin is a new cryptocurrency based on a meme. But since Elon Musk spoke about it, claiming it is the people\'s cryptocurrency, its value has continued to grow.
