1. Blockchain Basics
What is a blockchain?
A blockchain is a digital ledger of transactions distributed across many computers. Instead of one company or bank keeping a central record, thousands of computers around the world maintain copies of the same ledger.
Why it matters
No single point of control means no one can unilaterally change records. Transactions are transparent and permanent once confirmed. This is what makes crypto different from traditional finance.
Key terms
- Block: A group of transactions bundled together
- Hash: A unique fingerprint for each block
- Consensus: The method by which the network agrees on valid transactions
- Decentralization: No single entity controls the network
2. What is a Wallet?
Wallet types
Hot wallet (software): Connected to the internet. Convenient for frequent use, but more vulnerable to hacks. Examples: MetaMask, Trust Wallet, exchange apps.
Cold wallet (hardware): A physical device that stores your keys offline. Much more secure. Examples: Ledger, Trezor.
Private key = ownership
Whoever has the private key controls the funds. If you lose your private key, you lose your crypto forever. There is no "forgot password" button in blockchain.
Seed phrase
A seed phrase is 12-24 words that can recover your wallet. NEVER share it. NEVER store it digitally (no screenshots, no cloud storage, no email). Write it on paper and keep it somewhere safe.
Exchange wallet vs Self-custody
Exchange wallet: The exchange holds your keys. They control your funds. If the exchange gets hacked or goes bankrupt, your funds may be lost.
Self-custody: You hold your own keys. You have full control. But you are also fully responsible for security and backups.
3. How Exchanges Work
Centralized exchanges (CEX)
Companies that match buyers and sellers. They hold your funds, handle KYC (identity verification), and provide an easy interface. Examples: Coinbase, Binance, Kraken, Hibt.
Order book
A list of buy and sell orders at different prices. When a buyer's price matches a seller's price, a trade happens.
Market order vs Limit order
- Market order: Buy or sell immediately at the current best available price. Fast but you may pay slightly more (slippage).
- Limit order: Set your own price and wait for the market to reach it. More control but no guarantee of execution.
Liquidity
How easily you can buy or sell without affecting the price. High liquidity = tight spreads, fast execution. Low liquidity = slippage (your order moves the price).
4. Understanding Fees
Trading fees
Charged on every trade, usually 0.1% - 0.5%. Makers (who add liquidity) often pay less than takers (who remove liquidity).
Withdrawal fees
Charged when moving crypto off the exchange. These vary by coin and by exchange.
Network fees (gas)
Paid to blockchain miners or validators for processing transactions. These fluctuate with network congestion. On Ethereum, gas fees can spike to $50+ during busy times.
Spread
The difference between the buy (ask) and sell (bid) price on the exchange. On less liquid pairs, the spread can be 1-2% or more.
5. Spot vs Futures Trading
Spot trading
You buy the actual asset. You own it. Price goes up = profit. Price goes down = loss. Simple and straightforward. This is what most beginners should start with.
Futures trading
You bet on price direction with a contract. You do not own the actual asset. You can profit from both rising and falling prices.
Leverage
2x means a 10% price move becomes 20% profit or loss. 10x means a 10% move becomes 100% profit or loss. The higher the leverage, the faster you can be wiped out.
Liquidation
If the price moves against you too much, your position is automatically closed and you lose everything you put into that trade. With 10x leverage, a 10% move against you = total loss.
6. Security Essentials
2FA (Two-Factor Authentication)
Required for every exchange account. Use an authenticator app (Google Authenticator, Authy), not SMS. SIM swapping attacks make SMS-based 2FA vulnerable.
Phishing
Fake emails, websites, and messages designed to steal your login info. Always check URLs carefully. Bookmark your exchange and use those bookmarks.
Password manager
Use unique, strong passwords for every exchange. A password manager (Bitwarden, 1Password) makes this easy.
Withdrawal whitelist
Only allow withdrawals to pre-approved addresses. This prevents attackers from sending your funds to their own wallets even if they gain access.
Anti-phishing code
Set a custom code in your exchange settings. Real emails from the exchange will include this code. If it's missing, the email is fake.
7. Risk Management
Only invest what you can afford to lose completely
This is the golden rule. Crypto is volatile. Assume any money you put in could go to zero.
Diversification
Don't put everything in one coin. Spread across different assets to reduce single-point-of-failure risk.
Position sizing
A common rule: no more than 5% of your portfolio in a single risky asset. This way, even a total loss in one position won't destroy you.
Emotional control
Have a plan before you trade. Set entry and exit points in advance. Don't trade based on fear or greed.
The 24-hour rule
Wait 24 hours before making a large trade decision. This removes impulse and gives you time to think clearly.
