The Vibe: How much a crypto swings compared to the overall market (usually compared to Bitcoin).
The Details: Beta measures volatility or risk level. A beta of 1 means the coin moves about the same as Bitcoin (or the whole market). Higher than 1 (like 2 or 3) means it swings harder—bigger pumps in bull markets but bigger drops in bears. Lower than 1 means it’s calmer and less affected by market moves. Altcoins and meme coins often have high beta (wild rides), while stablecoins have beta near 0 (barely move).
Pro Tip: Check beta on sites like CoinGecko or TradingView to understand how risky a coin is. High beta = higher potential rewards, but you need strong risk management and diamond hands to handle the drops.
