#StaySAFU Cryptocurrencies are digital assets that use cryptography to ensure secure and decentralized transactions. They operate on a technology called blockchain, a public ledger that validates each operation without the need for intermediaries like banks. Bitcoin was the first to emerge, but today there are thousands, like Ethereum, which enables smart contracts. Its volatility has generated both investment opportunities and significant risks. Despite the controversies, cryptocurrencies are changing the way we conceive money, finance, and digital ownership. Governments, companies, and users are debating their regulation, while adoption continues to grow worldwide.
