A digital currency that functions as its own blockchain and is used as a medium of exchange.
A coin is a digital cash in cryptocurrency that is used as a medium of exchange and is a standalone blockchain. This coin is generated when users mine— solving difficult mathematical problems by utilizing computer power. Examples are Ethereum and Bitcoin.
A major factor driving the price increase is the strong demand for, and limited supply of cryptocurrency coins. Not to mention, paying less for it, and getting more for it afterward. Although not all cryptocurrencies are mined, popular ones like Bitcoin and Ethereum are, and those who participate can make good money.
