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:

Send money globally

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)

A meme is usually a joke or viral idea on the internet.

In crypto, meme coins are cryptocurrencies inspired by memes or internet culture.

Examples:

Dogecoin (DOGE) – based on a dog meme

Shiba Inu (SHIB)

Characteristics:

Often started as jokes

Driven by community and social media hype

Can rise or fall very fast

Usually high risk

How They Connect

Blockchain = the technology

Crypto = digital money built on blockchain

Meme coins = a fun (and risky) type of crypto

Simple analogy:

Blockchain = the road

Crypto = the cars

Meme coins = flashy cars that get attention 🚗😄
