Cryptocurrencies are digital assets designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. To put it simply, it is a way to send money from person to person (P2P) across a network of computers by anyone who chooses to participate. Like the internet, anyone can join this network by simply downloading free open source software on your computer or mobile device. Once you join, your computer will help you securely send or receive money to anyone in the world. Cryptocurrencies gives banking to the unbanked in underdeveloped countries by simply connecting to internet and downloading software.
