#TariffsPause Cryptocurrency is a digital or virtual currency that uses cryptography for security and is decentralized, meaning it's not controlled by any government or financial institution. Transactions are recorded on a public ledger called a blockchain, which helps to prevent counterfeiting and ensures the integrity of the transaction. The most well-known cryptocurrency is Bitcoin, but there are many others, such as Ethereum and Litecoin. Cryptocurrencies can be bought and sold on online exchanges, and some can even be used to purchase goods and services. The value of cryptocurrencies can fluctuate rapidly, making them a high-risk, high-reward investment.
