In Bitcoin chart analysis, a golden cross and a death cross are technical patterns formed when two key moving averages (MAs) intersect, signalling potential shifts in market trends.

Golden Cross
A golden cross occurs when a short-term moving average (e.g., the 50-day MA) crosses above a long-term moving average (e.g., the 200-day MA). This pattern is considered a bullish signal, indicating that momentum is shifting toward higher prices. Traders interpret the golden cross as a sign of potential upward trends and increasing buying interest. It typically happens after a prolonged downtrend and is often seen as a strong confirmation of recovery or the start of a bull market.

Death Cross
A death cross, on the other hand, happens when a short-term moving average crosses below a long-term moving average. This bearish signal suggests a potential downtrend or weakening momentum. It often appears after a sustained uptrend and signals that selling pressure may dominate. Traders often view it as a warning to reduce exposure or prepare for price declines.

Both patterns are widely used in Bitcoin chart analysis, but they are not infallible. They work best in trending markets and may produce false signals in choppy or sideways markets. Traders often combine these patterns with other indicators for more reliable predictions.
