Bitcoin climbed back above $80,000 within days of its October 15 slide as buyers rebuilt bid-side liquidity near the level, according to on-chain analytics firm Glassnode. The recovery, however, faces a dense resistance zone between $86,500 and $87,500, where older holders' cost bases, sell orders and leveraged liquidation clusters overlap. Adding to the uncertainty, U.S. spot Bitcoin ETFs returned to net inflows during the rebound, recording $653 million on October 19, even as trading volume stayed below its typical level from the past year, while the Federal Reserve's October 28 rate decision and MSCI's November 11 index review loom ahead.

Support Holds as ETF Inflows Return

Glassnode reported that Bitcoin briefly fell to an hourly close of $80,100 on October 15, dropping below the cost basis of U.S. spot Bitcoin ETFs, before the next hourly close moved back above that threshold. Cost-basis metrics of this kind estimate the average on-chain purchase price of a holder group, and price moves across them are closely watched because they show whether major cohorts are holding at a profit or a loss. Treasury companies — public companies that hold bitcoin on their balance sheets — tracked by the firm hold Bitcoin at an estimated average cost of $80,200.

The exchange order book showed substantial bids clustered around $80,000. Although the October 15 decline consumed much of that liquidity, buyers had replenished the orders by October 20, though the rebuilt bids remained smaller than their previous peak.

ETF inflows returned after a week of net outflows, reaching $653 million on October 19. Spot ETFs package bitcoin exposure into shares that trade in ordinary brokerage accounts, and their daily flow data has become a standard gauge of institutional demand since the products' January 2024 U.S. debut. Nevertheless, trading volume remained below a typical daily level recorded over the past year. Glassnode also found that realized profit-taking — a measure of coins moved on-chain at a gain — had slowed to roughly half the pace observed at September's market peak.

Resistance Cluster Near $87,000

Glassnode identified resistance between $86,500 and $87,500, where substantial sell orders coincide with liquidation clusters. Investors who purchased Bitcoin six to 12 months ago carry an average cost basis near $86,700, meaning a daily close above that level would return the cohort to profit on average.

Meanwhile, liquidation clusters near $85,000 and $87,000 — concentrations of leveraged positions that exchanges force-close once price reaches their margin thresholds — could accelerate price movements as leveraged positions unwind. However, the remaining sell orders at those levels could limit upward progress.

Fed Decision and MSCI Review Add Market Risks

Investors are also watching the Federal Reserve's October 28 rate decision and MSCI's November 11 index-removal announcement. Fed rate decisions steer the borrowing-cost and liquidity backdrop that risk assets trade against, making them recurring focal points for crypto markets. Index providers such as MSCI, meanwhile, determine which stocks passively managed funds must hold, which is why a removal decision can translate into forced selling. Strategy could face removal under MSCI's proposed classification rules for non-operating companies — a draft framework aimed at firms whose balance sheets are dominated by bitcoin holdings rather than operating businesses — and any removal would force index-tracking funds to sell its shares.

Separately, altcoin leverage has cooled, with fewer than 5% of tracked altcoins showing elevated funding rates, the recurring payments exchanged between perpetual futures traders that climb when long positioning grows crowded. Even so, open positions remain only about 5% below October's peak, leaving substantial leveraged exposure in the market.
