What is Cryptocurrency? A Beginner's Mega Guide
Cryptocurrency is a form of digital money powered by cryptography. It runs on blockchain technology, which ensures secure, transparent, and fast transactions — without banks or government control.
Why Was Crypto Invented?
Crypto emerged after the 2008 financial crisis, when people questioned traditional banking systems. The goal is financial freedom:
- Control your own money
- Send funds globally at any time
- Low-fee payments without intermediaries
- Equal access — no bank account required
So… What Exactly Is Blockchain?
A blockchain is a digital ledger shared across thousands of computers. Whenever you make a crypto transaction, it goes into a new “block,” then gets cryptographically linked to the previous one — forming a chain.
