[{"type":"paragraph","children":[{"text":"“Black September” is a meme most of us know well. Each time the calendar flips to September, Bitcoin, Ethereum, and the broader market seem cursed: weak rallies, frequent sell-offs.

Amusingly, the phrase “Black September” actually originated from the stock market."}]},{"type":"paragraph","children":[{"text":""}]},{"type":"paragraph","children":[{"text":"This September delivered on that reputation again.

Why does September so often underperform?"}]},{"type":"paragraph","children":[{"text":"• Tighter liquidity: Overseas markets enter earnings season, capital tilts toward traditional assets, and risk appetite falls.\n• Macro policy sensitivity: The Fed, ECB, and others often hold rate meetings in September; markets are hypersensitive to rate expectations.\n• Market psychology: History nudges investors to take profits or cut exposure early, creating a self-fulfilling loop."}]},{"type":"paragraph","children":[{"text":"In other words, September is often not a “trend-deciding month,” but a “risk-pre-release month.”"}]},{"type":"heading-two","children":[{"text":""}]},{"type":"heading-two","children":[{"text":"Behind the BTC and ETH Plunge: Liquidations Are Only the Surface"}]},{"type":"paragraph","children":[{"text":""}]},{"type":"paragraph","children":[{"text":"This sell-off once again reveals crypto’s brutality.

On the tape, it looks like a classic leverage cascade."}]},{"type":"paragraph","children":[{"text":"But pinning the drop solely on liquidations only grasps the surface.

Institutional flows cool: ETF net outflows exacerbate the drop"}]},{"type":"paragraph","children":[{"text":"Over the past two years, “institutionalization” was the market’s biggest certainty. Spot ETFs opened the gates for Wall Street capital, directly propelling BTC and ETH to new highs. Many investors even viewed ETFs as a “base-position backstop.”"}]},{"type":"paragraph","children":[{"text":"But in September, the tide turned:\n• ETH ETFs recorded multiple consecutive days of net outflows, totaling over $500 million.\n• Bitcoin ETFs also posted net outflows three times this week, totaling around $480 million."}]},{"type":"paragraph","children":[{"text":"\nTranslation: institutions trimmed risk and left. The “backstop bid” vanished. Remember, ETFs are merely pipes for money in and out — they don’t only flow one way. Plenty of retail traders fantasized that “with ETFs, it won’t drop,” but reality shows that when institutions see risk > return, they pull liquidity too."}]},{"type":"paragraph","children":[{"text":"In short, ETFs are a double-edged sword.

Without narrative support, ETH struggled to maintain lofty valuations — so a break below $3,900 became natural. It’s a reminder that crypto narratives are highly cyclical. From “AI + Crypto” to “RWA” to “DAT,” each story has a shelf life.

Macro factors: The Fed’s uncertainty"}]},{"type":"paragraph","children":[{"text":"Macro remains an inescapable variable.

Black swans: On-chain attacks fan the flames"}]},{"type":"paragraph","children":[{"text":"To make matters worse, recent security incidents on-chain helped fuel panic:\n• UXLINK was attacked, losing $11.3 million, alongside malicious minting.\n• On BNB Chain, GAIN was exploited for 5 billion tokens, and the price instantly plunged 90%.\n• The Hyperdrive stablecoin protocol account was attacked; all money markets were paused."}]},{"type":"paragraph","children":[{"text":"By dollar value, these weren’t massive. But amid fragile sentiment, any black swan can be magnified into a stampede. Especially for retail, seeing “hack, crash, mint” triggers first-order selling.

The core logic was a turn in flows and sentiment:\n• Institutions withdrew via ETFs, draining liquidity.\n• The DAT narrative cooled, and valuations reverted to rational anchors.\n• Macro tightened, with Fed policy expectations unstable.\n• Black swans added fuel, amplifying panic."}]},{"type":"paragraph","children":[{"text":"For investors, it’s another reminder: no single variable explains crypto price action.
