BTC market update: Spot BTCUSDT is around $77,624 as of 2026-08-21, with a 24-hour high of $79,500 and low of $72,498. That shows a strong rebound from the daily low, though it is still below the high.

On USDⓈ-M futures, BTC is around $77,685, up +6.39% today from 00:00 UTC. Funding is +0.01%, meaning longs are paying shorts, but it is not extremely elevated. Open interest is down -0.17% over the last hour, which may indicate some leverage is being reduced rather than aggressively added.

For the upward move to stay healthy, watch whether BTC can hold strength without funding and open interest rising too quickly. A return toward the daily low area would signal that the rebound is losing momentum. Futures positioning is slightly long-leaning: 50.6% of all accounts are long, while top traders are 66.8% long by position value—useful context, not a forecast.
