Bitcoin’s cost-basis heatmap shows $85,000 as one of the strongest support levels in the current cycle, with nearly 976,000 BTC, worth about $83 billion, acquired around this price, according to on-chain data.

This demand cluster marks a key zone where buyers stepped in with size. The cost-basis heatmap reflects wallet-level acquisition data, highlighting the price points where the most BTC was purchased. High-volume clusters tend to act as support during retracements, as holders are less likely to sell at a loss.

If Bitcoin approaches $85K again, the large concentration of previously acquired coins suggests this level could offer meaningful price stability.
