A interesting signal has been detected: After BTC faced resistance at the high of 82,850 last night, giant whales began a small-scale profit-taking move.

On-chain data shows that several known institutional addresses have clear signs of batch selling in the 80,900-81,200 range.
It is worth noting that the perpetual contract funding rate has turned negative to -0.0059%, indicating that bearish sentiment is starting to rise, but this level is not yet extreme.
Combined with the neutral reading of the Fear and Greed Index at 47, market sentiment remains relatively rational, with no signs of panic selling.
Even more interesting, I found that large buy orders on Coinbase Pro frequently appear around 80,830, suspected to be institutions building positions at this price level.
The 24-hour trading volume of 1.46B USD is not explosive, but the trading structure shows high participation from large traders.
From the behavior pattern of whales, this looks more like a technical adjustment rather than a trend reversal.
The BTC balance of several super addresses has not changed much, mainly active short-term trading accounts.
If the key support at 80,800 can hold, a new wave of buying interest is expected to enter.
Ongoing monitoring, especially paying attention to fund flows after the US stock market opens tonight.
