Cryptocurrencies work using a technology called blockchain. They are tokens that can be used as a form of payment in exchange for online goods and services. They carry a pre-determined store value of their own, just like any other fiat currency like the US dollar or the Indian rupee. Cryptocurrencies are digitally mined, where very sophisticated computers solve extremely complex computational mathematics problems. Their bitcoin interest mining is painstaking, costly and only sporadically rewarding. Buying digital assets is often related to how rare the digital tokens are and how many coins already went in the circulation. This gives a client a clear idea of their value. For example, RavenCoin total supply is estimated as 21000000000 and Crypto.com Coin circulating supply is 30263013692. For the time being, the price of RavenCoin is 0.026106 and the price of Crypto.com Coin is 0.06876.
