Day 1: What is Cryptocurrency?
📌 Definition of Cryptocurrency
Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates on a decentralized network, typically a blockchain. Unlike traditional currencies issued by central banks, cryptocurrencies are not controlled by any single authority. They are designed to be secure, anonymous, and immune to centralized interference.
📌 Origin and Vision of Bitcoin (2008 Whitepaper)
Bitcoin was introduced in 2008 by a pseudonymous creator named Satoshi Nakamoto in a whitepaper titled “Bitcoin: A Peer-to-Peer Electronic Cash System”. The whitepaper outlined a revolutionary vision:
• A decentralized digital currency that eliminates the need for intermediaries like banks
• Transactions verified by a distributed ledger (blockchain)
• A fixed supply (21 million coins) to prevent inflation Bitcoin officially launched in January 2009 with the mining of the genesis block. Its vision was to restore financial power to individuals, especially after the 2008 financial crisis.
