The Creator of Bitcoin
- Bitcoin was created by an unknown person (or group) using the pseudonym “Satoshi Nakamoto.”
- In October 2008, Satoshi published the famous Bitcoin whitepaper: “Bitcoin: A Peer-to-Peer Electronic Cash System.”
- In January 2009, Satoshi released the first version of the Bitcoin software and mined the very first block (called the Genesis Block).
🔹 About Satoshi Nakamoto
- Identity remains unknown — could be an individual or a team.
- Last confirmed online communication was in 2010, after which Satoshi disappeared.
- Some people have been speculated to be Satoshi (e.g., Hal Finney, Nick Szabo, Craig Wright), but none are proven.
🔹 Why the Mystery?
- Staying anonymous protects against government crackdowns, lawsuits, or personal risk.
- Adds to Bitcoin’s decentralized nature — no founder controls it.

How do I buy cryptocurrency?
1. Choose a Platform
You need a crypto exchange or app where you can buy crypto.
- Centralized Exchanges (CEX): Binance, Coinbase, Kraken, OKX (easy for beginners).
- Local P2P Platforms: Binance P2P, LocalBitcoins (good if your bank doesn’t allow direct purchases).
- Decentralized Exchanges (DEX): Uniswap, PancakeSwap (require a wallet and some crypto first).
🔹 2. Create & Verify Your Account
- Sign up with your email/phone.
- Complete KYC verification (upload ID, selfie) — required for most exchanges.
- Set up 2FA (Two-Factor Authentication) for security.
🔹 3. Deposit Funds
- Option A: Deposit money (USD, PKR, EUR, etc.) via bank transfer, debit/credit card, or mobile wallets (if supported).
- Option B: Use P2P trading — send money directly to another person’s bank account and receive crypto in your wallet inside the exchange.
🔹 4. Buy Cryptocurrency
- Search for the coin (e.g., BTC, ETH, USDT).
- Choose the trading pair (e.g., PKR/USDT or USD/BTC).
- Enter the amount you want to buy and confirm the order.
🔹 5. Store Your Crypto Safely
- You can leave it in the exchange wallet (convenient but riskier).
- For better security: transfer it to a private wallet:
- Hot wallets (apps like Trust Wallet, MetaMask).
- Cold wallets (hardware like Ledger, Trezor) — safest for large amounts.
⚠️ Tips for Beginners
- Start small (don’t invest more than you can afford to lose).
- Double-check wallet addresses (transactions are irreversible).
- Beware of scams — only use trusted platforms.
- Learn about fees (trading fee, withdrawal fee, network fee).
What is a crypto exchange?Definition
A crypto exchange is an online platform where you can buy, sell, and trade cryptocurrencies (like Bitcoin, Ethereum, or stablecoins).
- It works like a stock exchange, but instead of shares, you deal with digital assets.
🔹 Types of Crypto Exchanges
- Centralized Exchanges (CEX)
- Run by a company (like Binance, Coinbase, Kraken).
- You create an account, deposit money (fiat or crypto), and trade.
- User-friendly and secure, but the company controls your funds.
- Decentralized Exchanges (DEX)
- Examples: Uniswap, PancakeSwap.
- No central authority; trades happen peer-to-peer via smart contracts.
- You connect your own wallet (like MetaMask) and keep full control of funds.
- Usually requires more technical knowledge.
🔹 What You Can Do on an Exchange
- Buy crypto with fiat money (USD, PKR, EUR, etc.).
- Sell crypto and withdraw cash.
- Swap one crypto for another (BTC → ETH).
- Trade actively (day trading, futures, margin).
- Store crypto temporarily in exchange wallets (though safer in private wallets).
🔹 Why They’re Important
- Provide access to cryptocurrencies worldwide.
- Set the market price of coins based on supply and demand.
- Make crypto easier for beginners to enter.
Quick Answer (for exam/interview):
A crypto exchange is a digital marketplace where users can buy, sell, or trade cryptocurrencies, either through centralized companies (like Binance, Coinbase) or decentralized platforms (like Uniswap) without intermediaries.
