BTC 15-minute increase of 1.42%: On-chain capital inflow and technical breakout points resonate to trigger buying interest

Between 19:15 and 19:30 on March 9, 2026 (UTC), the BTC price increased by 1.42% within 15 minutes, with trading ranges between 68,377.3 and 69,365.3 USDT, and a volatility of 1.44%. This movement was significantly higher than typical intraday fluctuations, with market attention clearly heightened, and short-term buying pressure intensified volatility.

The main driver of this movement was net inflow of on-chain funds, triggered by large transfers from major wallet holders, along with a rapid increase in buying after key technical resistance levels were broken. During this process, market liquidity weakened somewhat, supporting a short-term price surge. Additionally, automated quantitative trading systems’ buy orders and price linkages in some derivatives markets further boosted upward momentum.

Furthermore, the number of active addresses and transaction counts increased during this period, indicating rising bullish sentiment. Partial liquidations in futures and other derivatives markets may have caused spot market resonance, while high-frequency strategy funds capitalized on arbitrage opportunities, pushing prices higher. Although there were no major macroeconomic or industry news events, the combined effect of multiple factors and liquidity expansion fully released upward momentum.

After the rapid rise, there remains a risk of pullback and high volatility. Attention should be paid to subsequent large on-chain transfers and market depth changes, especially if BTC repeatedly tests the 69,365 USDT level, which could signal shifts in fund flows. Short-term investors should stay alert to avoid sharp price swings caused by sudden liquidity drops. It is recommended to monitor on-chain data, active account behaviors, and macro environment news for more market insights.
