Technical Analysis
How to Read a Crypto Chart
Reading a crypto chart involves analyzing candlestick price action, timeframe intervals, technical support/resistance levels, and volume bars to understand supply-demand dynamics.
What Is a Candlestick?
A candlestick chart element visualizes four key price points for a specific timeframe: Open, High, Low, and Close (OHLC), with the body showing open-close delta and wicks displaying extreme highs/lows.
What Is Support in Crypto Charts?
Support is a technical price level where buying interest or order depth is repeatedly strong enough to pause or reverse a downward price trajectory.
What Is Resistance?
Resistance is a chart price ceiling where selling pressure and profit-taking reliably outweigh buyer demand, preventing the price from climbing higher.
What Is RSI (Relative Strength Index)?
The Relative Strength Index (RSI) is a momentum oscillator measuring the speed and magnitude of recent price changes on a scale of 0 to 100 to identify overbought (>70) or oversold (<30) conditions.

Risk Management
What Is Liquidation?
Liquidation occurs when a leveraged position suffers losses large enough to breach the mandatory maintenance margin threshold, causing the exchange to forcibly close the trade and seize collateral.
What Is a Stop Loss?
A stop loss is a conditional exit order placed with an exchange to automatically close a trade at a predetermined price level, capping potential financial losses if the market moves unfavorably.
What Is Risk Reward Ratio?
The risk-to-reward ratio measures prospective profit relative to potential loss on a trade setup. A 1:3 ratio means risking $100 of downside to capture $300 of upside.
What Is Position Sizing?
Position sizing is the mathematical determination of how many token units or contracts to purchase based on your total account capital, risk tolerance percentage, and distance to your technical stop loss.
Crypto Risk Management for Beginners
Risk management is the systematic framework of keeping potential losses within survivable boundaries through position sizing, stop losses, portfolio diversification, and emotional discipline.
How Much Should You Risk Per Trade?
Professional traders recommend risking between 1% and 2% of total account equity per trade, which ensures that even a 10-trade losing streak leaves over 90% of account capital intact.
Why Stop Loss Matters
A stop loss matters because it removes emotion from losing trades, prevents small setbacks from compounding into catastrophic account blowouts, and ensures you live to trade another day.

Security
What Is a Crypto Wallet?
A cryptocurrency wallet does not physically store coins; instead, it securely stores your cryptographic private keys that prove ownership of your assets on the public blockchain and authorize outgoing transfers.
Hot Wallet vs Cold Wallet
Hot wallets are connected to the internet for daily trading convenience but carry higher cyber-risk, while cold wallets remain air-gapped offline (such as hardware devices) to provide maximum protection against remote hacking.
What Is a Private Key?
A private key is a secret 256-bit alphanumeric number that mathematically matches your public blockchain address and gives you absolute authority to sign transactions and spend associated funds.
What Is a Seed Phrase?
A seed phrase (also known as a recovery phrase or mnemonic) is a sequence of 12 or 24 human-readable words that encodes the master cryptographic seed used to restore all your private keys and wallet balances.
Crypto Security Best Practices
Crypto security essentials include using hardware cold storage for long-term reserves, hardware 2FA keys (like YubiKey), offline metal seed phrase backups, and never clicking unverified links.
How to Protect a Seed Phrase
Protect your seed phrase by stamping it into fire- and water-resistant stainless steel plates, storing it in secure safes, and never entering it on any internet-connected computer or phone.
How to Avoid Crypto Scams
Avoid crypto scams by remembering that legitimate entities will never ask for your private key or seed phrase, offer guaranteed returns, or demand upfront crypto to release prizes.
How to Identify a Fake Crypto Website
Spot fake phishing sites by inspecting the exact browser URL for subtle character substitutions (punycode), verifying SSL certificates, and bookmarking official domain URLs directly.
Phishing Attacks in Crypto
Phishing attacks use deceptive emails, search engine ad clones, or direct messages to trick users into signing malicious wallet drainer transactions or exposing seed phrases.
How to Secure a Crypto Wallet
Secure your crypto wallet by maintaining separate wallets for daily DEX interactions versus long-term vaulting, revoking unused smart contract allowances, and requiring hardware signing.
What Is Two-Factor Authentication (2FA)?
Two-Factor Authentication requires two separate pieces of evidence to verify identity: a password plus a time-based authenticator code (TOTP) or physical hardware security key.
What Is a Hardware Wallet?
A hardware wallet is a dedicated physical device that generates and stores cryptographic private keys in an isolated secure element chip, signing transactions offline without exposing keys to the computer.
What Is a Rug Pull?

What Is a Crypto Ponzi Scheme?
A crypto Ponzi scheme is a fraudulent investment operation where returns to existing investors are paid using capital contributed by newer investors rather than genuine economic profits.
Curriculum Segment
Investment
What Is DCA (Dollar Cost Averaging)?
Dollar-Cost Averaging (DCA) is an investment discipline where an investor purchases a fixed dollar amount of an asset at regular calendar intervals regardless of market price fluctuations.
How Does Dollar Cost Averaging Work?
DCA works by exploiting price volatility: buying at fixed dollar amounts means you automatically purchase more units when prices dip and fewer units when prices surge, smoothing out your average cost basis.
DCA vs Lump Sum Investing
Lump sum investing deploys all available capital at once, which performs better in uninterrupted bull markets, whereas DCA mitigates downside regret and emotional stress during volatile bear markets.
What Is Staking?
Staking involves committing native proof-of-stake tokens to help validate transactions and secure a blockchain network in return for newly minted reward emissions.
What Is Tokenomics?
Tokenomics describes the economic design and incentive model of a cryptocurrency, including total supply, distribution schedules, vesting lockups, inflation rates, and utility.
What Is Circulating Supply?
Circulating supply is the number of cryptocurrency coins currently unlocked, publicly available, and actively circulating in the open market.
What Is Total Supply?
Total supply is the amount of tokens that currently exist, minus any coins that have been verifiably destroyed or permanently burned.
What Is Maximum Supply?
Maximum supply is the lifetime cap of coins that will ever be minted or mined into existence under a blockchain's hardcoded protocol rules.
Market Cap vs Price: The Unit Bias Trap
Unit bias occurs when inexperienced investors buy low-priced tokens thinking they have more room to grow, ignoring that a coin's market cap—not its individual price—determines true valuation.
Common Crypto Investment Mistakes
Key investing mistakes include panic selling bottoms, FOMO buying parabolic tops, failing to store keys on cold hardware, and concentrating 100% of capital into unproven meme coins.
How to Build a Simple Crypto Portfolio
Build a resilient simple crypto portfolio by establishing an anchor allocation in Bitcoin (40–60%), a secondary allocation in Ethereum (20–30%), and reserving cash/stablecoins (10–20%) for dips.
Crypto Portfolio Diversification

Advanced Trading
What Is Futures Trading?
Crypto futures are derivative contracts obligating or allowing market participants to buy or sell an asset at a predetermined price in the future, enabling leveraged long and short exposure.
How Does Crypto Leverage Work?
Crypto leverage functions through pooled liquidity or derivative contracts where you deposit margin collateral to borrow purchasing power, multiplying your price exposure proportionally.
What Is a Liquidation Price?
A liquidation price is the specific market quotation where losses equal your initial margin buffer minus maintenance requirements, prompting automated position closure.
How Does Futures Margin Work?
Futures margin operates across initial margin (required to open the contract) and maintenance margin (the absolute minimum equity required to prevent immediate forced liquidation).
Cross Margin vs Isolated Margin
Isolated margin restricts risk to the individual collateral assigned to a single trade, while cross margin shares your entire account balance across all open positions, risking total liquidation.
What Is Funding Rate?
The funding rate is a periodic payment exchanged directly between long and short traders on perpetual futures contracts to keep contract prices tethered to spot index prices.
What Is Open Interest?
Open interest represents the total number of outstanding active derivative contracts (longs and shorts) that have not been settled or closed on an exchange.
What Is a Liquidity Pool?
A liquidity pool is a crowdsourced smart contract reservoir of cryptocurrency tokens locked to facilitate decentralized trading, lending, and automated market making (AMM).
What Is Yield Farming?
Yield farming is the practice of locking or staking crypto assets in DeFi liquidity pools to generate passive yield, interest, and governance token incentives.
