Bitcoin now trades below the average acquisition price, or cost basis, of several key buyer cohorts. The short-term holder realized price, the True Market Mean, and the aggregate ETF cost basis, which cluster between approximately $71K and $83K, all sit above spot, converting what was formerly support into overhead resistance.
The short-term holder realized price reflects the cost basis of buyers who have entered positions within the past roughly 155 days. The True Market Mean measures a blended aggregate cost across the broader market. The aggregate ETF cost basis, near $83K, captures the average entry price of all U.S. spot ETF holders, which now reflects institutional capital flows with particular clarity.
Our research team's analysis identifies the ETF cost basis as the most structurally significant level in the current environment. When BTC recently approached $83K from below, de-risking emerged as institutional holders reduced their exposure upon recovering losses, making breakeven a behavioral trigger for selling rather than a springboard for further upside.
This mechanism of cost basis as resistance applies across all three cohorts and explains why the $71K–$83K zone functions as a supply wall that rallies must absorb to become durable.
The recent break below the 200-week moving average adds additional context. BTC has historically spent relatively little time below this level, although the 2022 cycle demonstrated that price can remain submerged for longer than prior cycles would suggest.
These levels define the resistance band, but the depth of the problem depends on how much capital is actually trapped behind it.
