Bitcoin rebounds to $89,500 as three signals gauge a potential bull run

Bitcoin rebounded to about $89,500, up roughly 1.4% over 24 hours after a brief dip into the mid-$80,000s. Analysts say a durable upswing hinges on three gauges: holding above the 200‑day EMA, a turn in U.S. spot ETF flows around the $86,600 cost basis, and short‑term holder behavior near realized prices.
