Cryptocurrency has become a prevalent term in internet slang and everyday conversations. At its core, cryptocurrency refers to a form of digital currency that uses cryptographic techniques to secure transactions and control the creation of new units. Unlike traditional currencies, it operates independently of central banks or government institutions, relying instead on blockchain technology.
Understanding Blockchain Technology
Blockchain is a decentralized, public ledger system that records all transactions among participants. It ensures data integrity and immutability through complex algorithms. Here's how it works:
- Each cryptocurrency transaction is added to the chain as a new "block"
- New blocks contain a hash of the previous block, creating a secure linkage
- This forms an ever-growing chain of transaction records

Risks and Considerations
