At $81,900, bitcoin sits at the boundary between its weekly support and resistance zones. Holding this level and clearing the concentration of trading activity overhead are the main tests for the recovery.

■ Weekly heatmap

As of October 22, the weekly price heatmap places the strongest point of control (POC) near $81,600. This marks the price with the greatest concentration of trading activity over the past week.

Bitcoin’s current price of $81,900 is slightly above that concentration. The weekly trading range is $79,800–$84,900, with the POC providing a reference for assessing its position within the range.

The weekly resistance zone spans $81,900–$82,900. Activity peaks near $82,000, making that level the immediate resistance reference.

Below the current price, the weekly support zone extends from $81,400 to $81,900, with activity concentrated most heavily at $81,600. Price stability within this band would be consistent with support holding.
