Bitcoin Tests $81,300 Support as ETF Cost Basis Nears $84,340

Bitcoin Is Trading Between Two Closely Watched Levels

Bitfinex Alpha Issue #226, published 12 October 2026, outlined the market setup: BTC is sitting between support that held at $81,300 and the average entry price of ETF investors, which Bitfinex estimates at about $84,340, a level it describes as having holders marginally underwater at the time of writing. The Bitfinex Alpha report attributed the ETF cost-basis figure to data from Checkonchain. For related coverage, see BTC Nears $74K as Bitcoin Breaks Above $73,700.

BTC briefly traded below $81,300 on 8 October, reaching $80,347 after a 7.9% decline from a 2 October high of $87,197. The session close recovered the level, which Bitfinex identifies as the former range high and a high-volume node where demand concentration has historically absorbed selling pressure.

The 8 October session also saw $1.18 billion in crypto liquidations, with long positions accounting for $1.05 billion of that total. That magnitude of forced selling concentrated in a single session underscores why the $81,300 level is structurally significant: it absorbed the drawdown and held.

Why $81,300 Support and the ETF Cost Basis Matter

What a support level signals

A defended support zone at $81,300 reflects a concentration of historical buy orders and on-chain cost basis for active participants. When price revisits such a level and closes above it after a liquidation cascade, it signals that demand at that price was sufficient to absorb the forced selling. Bitfinex’s identification of $81,300 as a former range high reinforces its relevance as a reference point, not a guarantee of future behavior.

How an average cost basis can frame investor positioning

Bitfinex’s stated aggregate cost basis of roughly $84,340 for US spot Bitcoin ETF investors functions as a structural reference, not a trigger. When price trades below the aggregate cost basis, the cohort as a whole is at a nominal loss, which can amplify redemption pressure and reduce incremental buying. Bitfinex characterizes ETF holders as marginally underwater at current levels, per its Checkonchain-attributed estimate; this figure has not been independently recalculated by a secondary source.

ETF flow data cited in the report adds context to that positioning. US spot Bitcoin ETFs recorded a $484.9 million outflow on 7 October, followed by a $21.1 million inflow on 9 October. The asymmetry between those two sessions reflects how quickly capital can rotate out of these vehicles when price dips below aggregate cost basis, and how modest the recovery bid was in the immediate aftermath.

BTC was trading at $81,674 at the time of data collection, down 2.6% on the day, placing it roughly $2,660 below the ETF cost-basis reference point and just above the $81,300 support floor. The Crypto Fear & Greed Index read 57 (Greed), a mismatch with price action that suggests sentiment has not yet repriced to match the drawdown.

What Traders May Watch Next

A hold below or above the two cited reference points

Bitfinex’s base case, as stated in the report, was BTC trading between $81,300 and $84,500 into the 14 October CPI release. The CPI print introduces a macro variable outside the range: a core CPI reading at or below 0.2% month-on-month would change the rate-expectation backdrop, while a 0.3% or higher reading would do the opposite. Bitfinex frames both scenarios conditionally, not as predictions.

If BTC loses $81,300 on a closing basis, the cost-basis floor that absorbed the 8 October liquidation cascade ceases to function as support, removing the lower bound of the range Bitfinex described. A recovery above the $84,340 ETF cost-basis reference would shift the aggregate ETF holder cohort back into nominal profit, potentially reducing redemption pressure. Neither outcome is forecast in the report; both are structural thresholds worth monitoring. For context on how prior BTC drawdown cycles resolved around macro inflection points, the pattern from late 2025 into early 2026 offers a parallel range compression that eventually resolved directionally on macro data.
