Heard of crypto but still not sure how it all fits together?
Whether you're investing, building, or just exploring Web3, understanding the fundamentals is key. Let’s break it down — no jargon, just clarity.
🔐 What Are Cryptocurrencies?
Cryptocurrencies are digital or virtual currencies secured by cryptography, making them nearly impossible to counterfeit or double-spend.
They’re built on blockchain technology, and unlike traditional currencies, they’re decentralized — no central bank or government controls them.
💸 Coins vs Tokens
🔹 Coins are the lifeblood of their blockchain — think ETH for Ethereum gas or BTC for Bitcoin transfers.
🔸 Tokens use existing chains for their own rules and functions, like stablecoins, governance tokens, etc.
🔑 Crypto Wallets: Your Key to the Chain
Wallets don’t store crypto. They store your keys (public & private) to access your funds.
Public key: Like your email — share it to receive crypto
Private key: Like your password — never share it
🔥 Types of Wallets
1. Hot Wallets:
- Connected to the internet
- Examples: MetaMask, Trust Wallet, Coinbase Wallet
- Convenient, but vulnerable to hacks
2. Cold Wallets:
- Offline storage
- Examples: Ledger, Trezor
- Best for long-term, high-value holdings
🛡️ Custodial vs Non-Custodial
💡 Not your keys, not your crypto.
If a platform holds your keys, they also control access to your funds.
🚀 Final Thoughts
Crypto isn’t just “digital money.” It’s programmable, borderless, decentralized value.
Whether you're trading, hodling, or just learning — know the basics and protect your assets.
