coin

This is one of the most important concepts in crypto.
Let’s explain it clearly and simply 👇
🔵 What is a Coin?
A coin is a cryptocurrency that has its own blockchain.
That’s why it’s called a coin — it works like digital money on its own network.
✅ Examples of Coins
BTC → Bitcoin blockchainETH → Ethereum blockchainBNB → BNB ChainSOL → Solana blockchain
🔧 What coins are used for
Paying network fees (gas)Sending and receiving valueSecuring the blockchain (mining or staking)
🟢 What is a Token?
A token is a crypto asset that is built on top of an existing blockchain.
🚫 It does NOT have its own blockchain.

✅ It uses another blockchain’s technology.
That’s why it’s called a token, not a coin.
✅ Examples of Tokens (on Ethereum)
UNI (Uniswap)AAVEUSDT (ERC-20)LINK
All of these run on Ethereum, not their own blockchains.
❓ Why Are They Called Tokens and Not Coins?
Because tokens:
❌ Do not secure the blockchain❌ Do not pay the main gas fees✅ Depend on another blockchain
They are like:
🎟️ Digital tickets, shares, or rights inside an ecosystem So the word token fits better than coin.
🧱 How Tokens Work (Very Simple)
1️⃣ A blockchain already exists (example: Ethereum)
2️⃣ Developers create a token using smart contracts

3️⃣ The token uses:
Ethereum’s securityEthereum’s networkEthereum’s transaction system
Example:
Ethereum blockchainETH = coin (native)UNI / AAVE / USDT = tokens (ERC-20)
🧠 Simple Analogy (Very Easy)
🏦 Blockchain = Country

💰 Coin = National currency

🎟️ Token = Ticket / Share / Voucher
Example:
Ethereum = CountryETH = MoneyUNI = Voting token inside Ethereum apps
⚠️ Important Note (Very Important)
Some projects start as tokens and later build their own blockchain.
Examples:
BNB → started as ERC-20 token → now has its own chainMATIC → token on Ethereum → Polygon blockchain exists
👉 When a project has its own blockchain, it becomes a coin.
🔑 Final Truth
1) No blockchain = Token
2) Own blockchain = Coin3) Coins power blockchains
4) Tokens power applicationsThat’s why we say governance tokens, not governance coins.
