What is Cryptocurrency?
Cryptocurrency is kind of new generation of the payment systems with high security that allows users to perform safe as well as real time online transactions. It is a medium of exchange like other Fiat currencies such as USD, GBP, EUR, etc. It is like the money you've got in your credit/debit card, that can be used for purchases. Transactions are visible in the bank statements/ledgers but you don’t get to touch it or feel it.
Put another way, cryptocurrency is computer hardware resources and electricity converted into lines of code with monetary and exchange value based on demand and supply logics.
