Cryptocurrency is a digital currency, created and held electronically. It uses cryptography to secure transactions, to control the creation and management of money, and to verify the transfer of assets.This means that you have the freedom to send or receive it anywhere in the world. In fact, most people in developed countries take advantage of this freedom everyday, as fiat currency (paper money) is not accepted by most institutions like banks to get paid. Crypto can also be used to buy goods online or even for investment purposes for large sums of money and start-ups going through angel investors. In short, crypto currencies are digital gold which you can use to buy things from Amazon, transfer money between countries which are otherwise difficult due to transaction fees etc.
