Blockchain & Cryptocurrency: A Complete Beginner’s Guide

Cryptocurrency and blockchain are two technologies that play important roles in today's digital economy. Unlike traditional banking, cryptocurrency and blockchain do not rely on centralized authorities such as banks or governments for processing financial transactions or controlling the movement of money.

• Permanent and cannot be changed or edited
• Visible to all members of the network
• Highly secure and reduces chances of fraud
