Cryptocurrencies are digital or virtual currencies based on cryptographic systems. They enable secure online payments without the use of third-party vendors. The term “crypto” refers to the various encryption algorithms and cryptographic techniques that protect these entries, such as elliptic curve encryption, public-private key pairs, and hashing functions.
Cryptocurrencies can be mined or purchased on cryptocurrency exchanges. Not all e-commerce websites allow purchases with cryptocurrencies. In fact, cryptocurrencies, even popular ones like Bitcoin, are rarely used for retail transactions. However, the rapidly rising value of cryptocurrencies has made them popular as trading tools. To a limited extent, they are also used for cross-border transfers.
