BTC 15-minute surge of 1.07%: On-chain activity spikes and ETF fund inflows synchronize to drive the move

From 2026-04-07 22:45 to 2026-04-07 23:00 (UTC), the BTC price recorded a +1.07% return, with a price range of 70733.5 to 71518.9 USDT, amplitude of 1.11%. Short-term volatility intensified, drawing significant market attention. On-chain data shows that the number of active addresses rose to 38,971, up 5.2% from the previous hour. The total number of addresses increased by about 252,780 within one hour. Network activity and new user growth improved significantly, becoming incremental market momentum amid abnormal movement. Spot trading volume reached $1.12 billion, up 8% month over month, setting a new high over the past week. Both on-chain and spot transactions were active at the same time. The primary drivers behind this abnormal move are the synchronized expansion of on-chain active entities and new user cohorts, combined with warming transaction volumes in the spot and derivatives markets—reflecting stronger capital entry intentions. Meanwhile, ETF net inflows were as high as $477 million. After two consecutive days of replenishing prior outflows, major exchanges saw BTC net outflows of about -2,800 BTC. Investors appear inclined to move assets from trading platforms to wallets for holding; overall fund flows are tilted to the strong side, pushing the short-term price upward quickly. In addition, the positioning structure changed: CME futures open interest fell to 112,340 BTC, indicating that institutions actively stepped back from risk-hedging. At the same time, open interest on major trading platforms’ futures rebounded to 129,080 BTC, suggesting that retail investors and high-leverage funds are dominating spot and derivatives volatility. On the daily technicals, a head-and-shoulders top structure formed; market sentiment is tilting toward the long side. The leverage structure is imbalanced, which can easily trigger a short-term forced-liquidation chain reaction, amplifying volatility resonance. The liquidity environment remains fragile. Although combined spot and derivatives trading volume is currently trending higher, the overall base is still lower than at the end of 2023. The risk of price-movement anomalies being magnified by sudden buy-side pressure remains. In the short term, it is important to monitor $64,888 key technical support and the high-risk leverage long position zone around $64,533 (about $113 million in high-leverage positions). If the price retraces into these areas, the liquidation chain may trigger a second round of volatility. Investors are advised to watch out for the risk of sharp pullbacks under fragile liquidity conditions, and to track changes in on-chain funds, ETF fund flows, and derivatives positioning structure.
