What's the difference between price support and price resistance?

Support and resistance are price levels where assets tend to stop falling or rising. Support is a price floor where buying interest increases, preventing further decline—think of it as a "bounce point." Resistance is a price ceiling where selling pressure increases, stopping upward movement. For example, if Bitcoin repeatedly bounces at $40,000 without breaking below, that's support. If it repeatedly fails to break above $45,000, that's resistance. These levels form from historical trading activity where many buyers or sellers entered positions. Traders use these levels to plan entry and exit points, as they often signal potential price reversals or breakouts when broken.
