#DeFiGetsGraded Cryptocurrency is a digital or virtual form of currency that uses cryptography for security purposes. Unlike traditional currencies issued by governments, cryptocurrencies are typically decentralized and operate on a technology called blockchain. The first cryptocurrency, Bitcoin, was created in 2009 by an unknown entity known as Satoshi Nakamoto. The blockchain is a distributed public ledger that records all transactions, ensuring their security and transparency. This peer-to-peer system allows anyone, anywhere, to send and receive payments without the need for a bank. Alongside Bitcoin, there are thousands of other cryptocurrencies, often referred to as altcoins, such as Ethereum, which has gained popularity for its ability to support complex transactions. Cryptocurrencies are stored in digital wallets and can be purchased from electronic trading platforms. While they offer the potential for a new era of digital finance, they are also known for market volatility and are still considered a relatively new and evolving asset class.
