What is Bull Market?
A period when prices are rising and optimism is high.
A bull market is a sustained stretch of rising prices — in stocks, crypto, or any asset — usually paired with confidence, greed, and everyone suddenly becoming an investing genius.
The name comes from how a bull attacks: horns thrusting upward. Bull markets feel great and make risky bets look smart, which is exactly when people get careless.
The opposite is a bear market. Fortunes are made in bull markets and lost by assuming they last forever.
