Question: What is Cryptocurrency first of all? Is this the Bitcoin?
Cryptocurrencies are digital assets that use cryptography to enable secure transactions and the control of mining (creation of more digital currency).
They were invented by a group of people that believed transactions should not need a central server or authority, but rather, be shared, peer-to-peer.
This is else known as restricted entries in a database and subsequently the solution to the “double-spend” problem, i.e. sending the same Cryptocurrency to two people.
Bitcoin is a Cryptocurrency using the above technology.
