The Foundation: Core Crypto Concepts
Before we dive into the slang and trading lingo, let's cover the fundamental building blocks. These are the terms that actually make crypto possible.
Cryptocurrency
Digital money that uses cryptography for security. Unlike your bank account, crypto operates independently of governments and traditional financial institutions. Think of it as internet-native money that you actually own and control.
Examples: Bitcoin (BTC), Ethereum (ETH), Solana (SOL).
Bitcoin (BTC)
The OG, the legend, the one that started it all. Launched in 2009 by the mysterious Satoshi Nakamoto, Bitcoin introduced the world to decentralized, peer-to-peer money. It's still the biggest and most recognized cryptocurrency.
Public Key & Private Key
Your public key is like your email address, and you can share it with anyone who wants to send you crypto. Your private key is like your password, so if you lose it or someone steals it, your crypto is gone forever. Never, ever share your private key. Write it down, store it safely, and treat it like the nuclear codes.

Exchange
Where you actually buy, sell, and trad
