Cryptocurrency is a digital or virtual currency that uses cryptography for security and is not controlled or regulated by any government or central bank. Unlike traditional currency, it is decentralized and secured using advanced encryption technology. Cryptocurrencies are not physical objects like coins or bills; they are digital records that exist on distributed ledgers and can be exchanged through the internet without the use of an intermediary such as a bank. Cryptocurrencies are highly volatile, meaning they can fluctuate significantly in price within a short period of time. Additionally, transfers of cryptocurrencies are usually faster and carry lower transaction fees than those of traditional currencies.
