Introduction
In today’s rapidly evolving digital world, money is no longer limited to physical cash or traditional banking systems. Over the past decade, cryptocurrencies have emerged as a revolutionary financial innovation, and at the center of this transformation is Bitcoin (BTC).

What is Bitcoin?
Bitcoin is a decentralized digital currency that allows people to send and receive money over the internet without relying on banks or financial institutions.

Every transaction made using Bitcoin is recorded on this public ledger, which anyone can view, but no one can alter.
