BTC 15-minute increase of 0.49%: On-chain activity and whale net inflows jointly drive the price upward

2026-04-09 08:30 to 08:45 (UTC), the BTC price saw a short-term spike. K-line data shows a return rate of +0.49%, with the price range at 70979.6 to 71333.3 USDT and a swing of 0.50%. During this period, trading volume clearly increased, market attention rose, volatility strengthened, and a large amount of capital flowed in. The main drivers behind this price move are the sustained growth in the number of active addresses on-chain and net inflows of whale funds. Data shows that BTC active addresses have exceeded 120k; average daily on-chain transaction volume has surpassed $2 billion, effectively reflecting genuine user participation and ongoing capital inflows. Meanwhile, on-chain monitoring confirmed that whales net flowed in before and after the window, boosting market confidence and pushing prices higher. In the derivatives market, bullish sentiment dominates; open interest in futures broke $20 billion, funding rates turned positive, and the market is being driven by active trading rather than liquidation activity.

In addition, the continued accumulation of institutional funds and a favorable macro backdrop have amplified this rally. From 2025 to 2026, institutional holdings rose rapidly, and clearer regulations in the US and Europe drove long-term capital inflows into BTC. During the spike period, easing global geopolitical tensions and rebounds in gold and US stocks boosted risk appetite, benefiting BTC through capital inflows. On the technical side, price is pressing toward the upper end of the range, and increased trading volume has strengthened proactive buy orders. On-chain fees remain stable, the network continues to expand healthily, and this further supports the uptrend.

Current volatility risks to watch include whale behavior and derivatives leverage dynamics. In the future, large capital withdrawals or extreme market conditions could trigger sharp adjustments. It is recommended to focus on monitoring on-chain fund flows, the structure of the futures market, key technical support levels, and global macro news. With short-term volatility increasing, investors should guard against liquidation risks and continue to follow related market updates.
