Changes in Bitcoin's long-to-short-term holder ratio can signal market tops or bottoms. A rising long-term holder (LTH) supply, typically held over 155 days, often indicates accumulation during bear markets, suggesting a potential bottom as confidence grows. Conversely, a decreasing LTH supply and increasing short-term holder (STH) supply, reflecting profit-taking or new entrants, often occur during bull markets, potentially signaling a top. Historical data shows LTH supply drops during rallies, as seen in 2021, while STH supply surges. Recent trends, like declining STH reserves since November 2024, suggest reduced liquidity and possible corrections, while LTH accumulation hints at bullish reversals. However, the ratio alone isn’t conclusive; it’s best used with other metrics like price action and whale activity for accurate predictions.
