Bitcoin is defending the line where ETF money breaks even.

$BTC trades near $82.5K.

Support sits at $80K–$81.5K, where the 50-day average meets last month's highs and the largest buy orders cluster near $81K.

A deeper floor lies at $75K–$76K by the 100- and 200-day averages.

Resistance starts at $83K–$84K, with a heavier sell wall at $86.5K–$87K capping the recent peak.

Bitcoin's investment case now runs through Wall Street as much as through its network.

US spot ETFs hold a cumulative $57.3B in net inflows since launching in January 2024, but October flipped negative after $484.9M left in a single day on Oct 7, the largest outflow since June.

With $BTC trading near $82.5K, the average ETF buyer sits almost exactly at breakeven around $81.7K, which explains the rush for the exit.

Corporate treasuries are the other institutional bid: Strategy (MSTR) now holds 848,000 $BTC, over 4% of total supply, after adding 334 coins in early October.

The company posted a ~$21B Q3 gain on its digital assets, reversing Q2's $8.2B loss.

Bitcoin runs on proof-of-work, secured by roughly 916 EH/s of network computing power.

Publicly traded miners now control over 40% of that hashrate, led by Bitdeer at 79.9 EH/s and MARA at 70.3 EH/s.

September was brutal for miner economics: hashrate rose 1.7% while revenue per exahash fell 2.6%, and October looks tougher with hashrate up 11% against a 5% price gain.

Bitcoin commands 59.2% of the $2.79T crypto market.

That share has been climbing — dominance touched 60% this week, a one-month high, as capital rotated into $BTC during the selloff.

For altcoin holders watching, the Altcoin Season Index sits in the 30s, far below the 75 threshold that marks a true altseason. This is still Bitcoin season.

Sentiment is cooling but not panicking: the Crypto Fear & Greed Index reads 59 (Greed) as of Oct 9, down from 71 three days earlier.

The macro backdrop is hostile: the Fed raised rates to 3.75-4.00% on Sept 16, its first hike since 2023, while Treasury yields sit near 5.35%.

QCP Capital frames Q4 as a stalemate between structural ETF demand and macro pressure.

Against gold near $4,200, Bitcoin is the volatile challenger for the same safe-haven bid.

Against $ETH at 10.8% dominance, Bitcoin keeps winning the institutional allocation while ETH ETFs just logged seven straight outflow sessions.

MC $1.66T / FDV $1.66T.
