BTC 15-minute increase of 1.17%: Safe-haven funds flow back and futures leverage resonance drive the rebound

On February 18, 2026, from 15:30 to 15:45 (UTC), BTC recorded a 1.17% gain in the 15-minute candlestick, indicating a short-term rebound. During this period, market sentiment was extremely fearful, trading volume remained high, highlighting increased short-term volatility and attention.

The main drivers of this movement were changes in capital liquidity preferences and heightened risk aversion. Advances in Ethereum mainnet technology led to a reshuffling of the Layer 2 ecosystem, with valuation bubbles deflating, causing high-risk capital to flow out en masse and shift toward mainstream cryptocurrencies like BTC. Meanwhile, BTC served as a safe-haven anchor, attracting substantial short-term buying and enabling a rapid rebound at key support levels. Additionally, leverage expansion in the derivatives market played a significant role, with leading platforms like CME and open interest across the market continuing to grow, indicating institutional and professional funds amplifying short-term price fluctuations through leverage, thus boosting BTC’s short-term gains.

At the same time, multiple secondary factors created market resonance. First, at the industry level, Ethereum’s low-fee structure attracted attention, making mainstream coins the preferred safe-haven for funds. Second, frequent cross-chain bridge security incidents triggered capital migration from high-risk projects, further strengthening BTC’s inflow effect. Technically, BTC was at a critical support level; once supported by capital, an upward push could trigger active short-term trading. Moreover, the fear and greed index dropped to 12/100, reflecting extreme fear, with investors favoring short-term speculation, and liquidity and market sentiment amplifying volatility.

Although BTC gained 1.17% in this round, active short-term trading and leveraged positions still pose significant volatility risks. It is recommended to monitor subsequent support and resistance levels, on-chain major fund flows, and overall market sentiment evolution. Macro policies and industry technological changes may continue to influence market structure, so caution is advised against sudden sharp rises or falls in the short term.
