Regulatory announcements, major exchange listings or delistings, and macroeconomic data releases (inflation reports, Fed commentary) often trigger crypto volatility. Network upgrades, security incidents, or large on-chain transactions can also shift sentiment.

Additionally, options expiry, liquidation cascades, or whale trading activity could create sharp intraday swings.
