- Token: A digital asset issued on an existing blockchain, representing utility, ownership, or value.
- Node: A computer participating in a blockchain network by verifying and relaying transactions.

Technical Analysis: 9 Key Concepts for Smarter Trading
Technical analysis helps traders predict future price movements by studying historical data and chart patterns.
It’s widely used in crypto due to the absence of traditional fundamentals like earnings reports. Here are nine essential terms:
- Technical Analysis: Evaluating price trends and patterns to forecast future movements.
- Indicator: Mathematical calculations based on price or volume used to inform trading decisions (e.g., RSI, MACD).
- Support Level: A price level where buying interest is strong enough to prevent further decline.
- Resistance Level: A price zone where selling pressure tends to halt upward movement.
- Trend: The general direction of price movement—upward (bullish), downward (bearish), or sideways (range-bound).
- Candlestick Chart: Visual representation showing open, high, low, and close prices over time—essential for technical analysis.
- Moving Average (MA): Smooths out price data over time to identify trend direction; common types include SMA and EMA.
- Market Depth: Shows real-time buy and sell orders at various price levels—useful for gauging supply and demand.
- Liquidity: How quickly an asset can be bought or sold without causing large price swings. High liquidity means tighter spreads and smoother trades.
