Bitcoin cools after testing the $81,000 zone, leaving fund flows as the key signal

Bitcoin entered August 31 with traders still focused on the recent test of the $81,326 area and the pullback that followed.

The retreat below $80,000 does not automatically break the rebound, but it changes the question from price excitement to flow durability.

For the next session, ETF demand and spot liquidity matter more than the headline level because they show whether larger buyers are still adding exposure.
