Crypto is digital money secured by cryptography and recorded on a blockchain.
Bitcoin was the first cryptocurrency and remains the most well known.
To enable money transfer without banks or central control.
You sign a transaction with your private key; the network verifies it.
A wallet stores the keys that control your coins, not the coins themselves.
Hot wallets are online and convenient; cold wallets are offline and safer.
Public key = address to receive; private key = control — never share it.
Exchanges let you buy, sell, and trade cryptocurrencies.
Any crypto other than Bitcoin is called an altcoin.
Stablecoins peg their value to assets like the US dollar.
Speculation, news, and limited regulation cause big price swings.
Some coins reward miners or validators for securing the network.
Network fees pay to process your transactions.
Crypto is decentralized, borderless, and programmable.
Phishing, fake giveaways, and rug pulls target crypto users.
Lose your private key and you lose your funds — back it up safely.
Many countries tax and regulate crypto activity.
Payments, savings, remittances, and DeFi are real uses.
Crypto can lose value fast and isn’t insured like bank deposits.
Start small, use trusted platforms, and secure your keys.
