1. Crypto (Cryptocurrency)
Crypto is digital money that exists only online.
It uses cryptography for security.
It is not controlled by a bank or government.
Examples: Bitcoin (BTC), Ethereum (ETH), Solana (SOL)
People use crypto to:

Invest or trade
Pay for goods and services (in some places)
2. Blockchain
A blockchain is the technology that makes crypto work.
Think of it like a public digital ledger:
Every transaction is recorded in “blocks”
Blocks are linked together in a “chain”
Once recorded, data cannot be changed
Key features:
Decentralized (many computers verify transactions)
Transparent (anyone can view transactions)
Secure
Blockchain is also used beyond crypto, such as:
Supply chain tracking
Voting systems
NFTs
Smart contracts
3. Meme (Meme Coins)

In crypto, meme coins are cryptocurrencies inspired by memes or internet culture.
Examples:
Dogecoin (DOGE) – based on a dog meme
Shiba Inu (SHIB)
