Alternative currencies

Alternative currencies are digital or virtual currencies that serve as substitutes for conventional, government-issued money. Unlike traditional currencies like the US Dollar or Euro, alternative currencies operate on decentralized systems, often leveraging blockchain technology. These currencies can include cryptocurrencies such as Bitcoin and Ethereum, which use cryptographic principles to secure transactions and control the creation of new units. Alternative currencies offer several advantages, including faster transaction speeds, lower fees, and greater privacy. They are also used in various innovative applications, such as smart contracts and decentralized finance (DeFi). However, their value can be highly volatile, and they may not be universally accepted.
