The cryptocurrency market suffered steep losses on October 21, 2025. Bitcoin traded around $107,000 while Ethereum slipped below $3,900. The decline marks one of the most severe corrections of the year.

President Donald Trump’s announcement of a 100% tariff on Chinese tech imports sparked the sell-off. The trade policy escalated tensions between Washington and Beijing. Global risk appetite collapsed as investors fled volatile assets.
The tariff news triggered mass liquidations across crypto futures markets. Over $19 billion in leveraged positions were wiped out last week. This represents the largest single-day liquidation event in cryptocurrency history.
Bitcoin had surged above $126,000 earlier in October. The rapid climb created excessive leverage throughout the market. Traders who borrowed money to amplify positions faced forced closures when prices reversed.
Rising U.S. real yields and a strengthening dollar added pressure. These macroeconomic factors typically hurt risk assets like cryptocurrencies. The combination of trade war fears and unfavorable monetary conditions created a perfect storm.
ETF Outflows Accelerate Decline
Spot Bitcoin and Ethereum exchange-traded funds experienced heavy withdrawals. These investment vehicles had provided stability during 2025’s bull run. Institutional investors pulled capital to reduce portfolio risk.
The ETF outflows created a cascade effect. Large withdrawals drain market liquidity. Declining collateral values then force additional sales as margin requirements fail.
The CoinMarketCap Fear & Greed Index dropped to 33. This reading signals deep fear among market participants. Futures open interest declined as traders exited positions.
Funding rates turned negative across major exchanges. This metric indicates traders are betting on continued price drops. The bearish sentiment reinforced selling pressure.
Altcoins Hit Harder Than Bitcoin
Alternative cryptocurrencies suffered larger percentage losses. Solana, Cardano, and Avalanche posted weekly declines between 25% and 40%. Smaller cap tokens typically experience amplified volatility during corrections.
Some institutional buyers viewed the crash as an accumulation opportunity. Firms like BitMine and Strategy reportedly purchased coins during the dip. These investors compare the current phase to previous consolidations before new price highs.
Analysts emphasize the crash followed historic price peaks. This differs from bear market corrections that start from lower levels. Structural demand for digital assets remains present despite the sharp pullback.

The broader stock market showed mixed performance on October 21. Major index futures declined slightly over 0.1%. Investors focused on upcoming earnings from Netflix and General Motors.
President Trump said he expects to reach a fair deal with Chinese President Xi Jinping. The two leaders plan to meet later this month in South Korea. This statement raised hopes for trade tension resolution.
The Federal Reserve is expected to cut interest rates by a quarter-point at its late October meeting. Friday’s upcoming CPI report will influence that decision. Lower rates typically support risk asset prices.
If macroeconomic pressures ease and ETF inflows return, traders anticipate gradual recovery into late 2025. Bitcoin’s drop to $107,000 occurred after reaching $126,000 earlier this month as trade tensions and overleveraged positions combined to create historic liquidations.
