1. Understand the Difference between Exchange and Wallet
Exchange (e.g., Binance, Coinbase, Tokocrypto) is used for buying and selling assets, but it is not the safest place for long-term storage.
Wallet (crypto wallet) is a safer place to store assets, especially if you control the private key.
> 🔑 Main principle: "Not your keys, not your coins"
---
2. Types of Wallets & Their Security
Type of Wallet Security Description
Hot Wallet Medium Connected to the internet. Easy to use but vulnerable to hacks. Example: MetaMask, Trust Wallet. Cold Wallet High Offline. Safe from online attacks. Example: Ledger, Trezor. Paper Wallet High Private key printed on paper. Safe but easy to lose or damage. Custodial Wallet Low-Medium Controlled by a third party. You do not have the private key.
---
3. Private Key vs Seed Phrase
Private Key: Direct access to one wallet.
Seed Phrase (12/24 words): Master key to access all wallets created from that phrase.
> ⚠️ Never share your seed phrase or private key with anyone!
---
4. Protect Your Account & Wallet
Use strong and unique passwords for each crypto account.
Enable 2FA (Two-Factor Authentication) on all exchanges and wallets.
Never store your seed phrase or private key in the cloud (Google Drive, iCloud, etc.).
Keep a backup of your seed phrase in a secure physical location (e.g., safe).
---
5. Be Wary of Phishing and Scams
Always check the website URL before logging in. Many fake sites mimic exchange sites.
Do not click on suspicious links from emails, Telegram, or Twitter DMs.
Beware of fake airdrops, scam bots, and unverified DeFi projects.
---
6. Pay Attention to Smart Contracts
Do not carelessly connect your wallet to dApps/websites with unclear reputations.
Use tools like DeBank or Revoke.cash to check and revoke permissions from unknown smart contracts.
A crypto chart is a visualization of the price movements of a crypto asset such as Bitcoin or Ethereum over time. Charts help traders analyze trends, determine entry/exit points, and understand market psychology.

🧱 1. Commonly Used Chart Types
Chart Type Description
Line Chart A single line connecting the closing prices of each period. Simple. Bar Chart Displays the opening, highest, lowest, and closing prices (OHLC). Candlestick Chart 🕯️ A visual version of the bar chart, most popular in crypto trading.
---
🕯 2. How to Read Candlesticks
Each candlestick shows price movement over a certain time period (e.g., 1 minute, 1 hour, 1 day).
Body: between the opening (open) and closing (close) prices
Green (bullish): close > open
Red (bearish): close < open
Wick (shadow): upper and lower lines show the highest and lowest prices
The size of the candle indicates the strength of the movement
Example: If a BTC 1H candle is large and green → it means buyers dominated the last hour.
---
📈 3. Price Trends (Trend)
Uptrend: prices make higher highs and higher lows
Downtrend: prices make lower highs and lower lows
Sideways / Consolidation: prices move within a narrow range (support & resistance)
Use trendlines or moving averages to identify trends.

🛠 4. Important Tools & Indicators
Indicator Function
Moving Average (MA) Shows the direction of the overall trend RSI (Relative Strength Index) Assesses whether an asset is overbought (>70) or oversold (<30) MACD Measures momentum & potential trend reversals Volume Indicates the strength of price movement (high volume = strong confirmation) #CryptoCharts101
A stablecoin is a cryptocurrency whose value is pegged to stable assets like USD, EUR, or gold. The goal is to provide price stability amidst the volatility of the crypto market.

⚖️ High regulatory pressure (especially from the US & EU)
🏛️ Concerns about replacing the role of central banks
🔍 Privacy issues & user data dominance
💥 Risk of financial monopoly in a closed ecosystem

🔮 Future: Stablecoin + Big Tech = Fintech 2.0?
The combination of technology, a large user base, and global infrastructure makes stablecoins from Big Tech highly influential on a macro scale.
But strict oversight is needed to prevent disruption to the traditional financial system.
Liquidity = How easily and quickly you can buy/sell an asset without moving the price too far.
📌 The higher the liquidity, the easier it is to trade at a fair price. 📌 The lower the liquidity, the greater the slippage and volatility.
---
🧪 Simple Example
Liquid market: You buy 1 BTC, the price hardly changes.
Illiquid market: You buy 1 BTC, the price suddenly rises dramatically because the order book is thin.
---
📊 Characteristics of Liquid Assets/Pairs:
✅ High transaction volume ✅ Many buyers & sellers ✅ Small spread (the difference between buying and selling price) ✅ Thick order book
Example:
BTC/USDT → Very liquid
Small altcoins / new tokens → Tend to be illiquid
---
🧱 Types of Liquidity:
1. Market Liquidity
How actively the asset is traded in the market.
Affected by volume, spread, and trader activity.
2. Exchange Liquidity
How large the asset reserves held by the exchange are to meet user orders.
---
⚠️ Risks of Illiquid Assets
📉 High slippage: Buying/selling prices become suboptimal
⏳ Orders are hard to execute
🎢 Prices can be easily moved by large traders (whales)
💀 Vulnerable to market manipulation & rug pulls
---
🧠 Tips to Avoid Illiquid Assets:
✔️ Always check the 24-hour volume ✔️ Look at the bid-ask spread ✔️ Avoid FOMO on new tokens without volume ✔️ Use CEX/DEX with a high reputation #Liquidity101
Here is a brief, clear explanation of the comparison between Centralized Exchange (CEX) vs Decentralized Exchange (DEX) in a concise format, ⚖️ CEX vs DEX: What’s the Difference?
🏢 CEX (Centralized Exchange)

No KYC
More private & permissionless
Faster access to new tokens
❌ Disadvantages:
UI/UX can be confusing for beginners
Gas fees can be high (especially on Ethereum)
Vulnerable to slippage and low liquidity on small tokens

Buy & sell crypto directly. You truly own the asset after purchase. 🟢 Suitable for beginners 📌 Example: Buy BTC at $30K, sell when it rises to $35K 💸 Low fees ⚙️ Order: Limit / Market / Stop-limit / OCO
⚡️ 2. Margin Trading
Use leverage (borrowed funds) to increase your position. ⚠️ Higher risk due to potential liquidation 📌 Example: Capital $100 → Leverage 5x → Position $500 🧠 Suitable for intermediate traders
📉 3. Futures Trading
Trading contracts (not direct assets), can go long (up) or short (down). 📈 Leverage up to 125x 💣 High risk, quick profit or loss 📌 Type: USDT-M / COIN-M ⚠️ Must understand liquidation & funding fee
🔄 4. Convert
Instantly exchange crypto assets, without looking at the order book. 👌 Suitable for super beginners 📌 Example: Convert BNB to ETH with 1 click ⚠️ Spread may be larger than spot
🤖 5. Strategy / Copy Trading
Auto-trading using bots or following pro trader strategies 📌 Type: Grid, DCA, or Copy Trading 🛏️ Suitable for passive income ⚠️ There are still risks, make sure to understand the strategy
🤝 6. P2P Trading
Buy/sell crypto directly to other users using local banks/e-wallets 📌 Example: Buy USDT using BCA transfer ✅ 0% fee for users 🛡️ Use Binance escrow for security #TradingTypes101
