💰 Cryptocurrency 101: Coins, Tokens, Wallets & How It All Works

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.
