Currency is a form of money that is issued and used by governments or other organizations as legal tender. Currencies are typically traded on exchanges between buyers and sellers, allowing for price discovery in the global marketplace. The most commonly-traded currencies include the US dollar (USD), Euro (EUR), Japanese yen (JPY) and British Pound Sterling (GBP). In addition to these major currencies, there are many smaller currency units such as those from countries within the European Union, Canada, Australia and New Zealand.
Cryptocurrencies are digital forms of money created using cryptography algorithms which can be bought or sold online at various cryptocurrency exchanges around the world. These virtual coins use distributed ledger technology known as blockchain to keep track of all transactions securely without any central authority controlling them; instead they rely on peer-to-peer networks comprised of “miners” who validate each transaction separately before adding it into a shared public ledger called a block chain. Popular cryptocurrencies include Bitcoin (BTC), Ethereum(ETH) Litecoin(LTC), Ripple(XRP)and Dash among others . Unlike fiat currencies like USD , EUR etc., crypto assets have no physical representation but their value oscillates depending on market demand & supply dynamics determined by speculation & investment activity in these markets unlike traditional stock/commodity markets where prices depend primarily upon underlying asset fundamentals & macroeconomic factors influencing its demand/supply balance over time..
