BTC 15-minute increase of 0.64%: On-chain large fund outflows and ETF net inflows resonate to boost spot buying demand

From April 17, 2026, 12:45 to April 17, 2026, 13:00 (UTC), Bitcoin achieved a +0.64% return within a 15-minute window amid overall market volatility convergence, with a price range of 75,720.6 to 76,256.6 USDT and an amplitude of 0.71%. Driven by short-term buying pressure, market attention significantly increased, with spot and derivatives trading volumes expanding in tandem, and overall volatility notably intensifying.

The main driver of this abnormal movement stems from continuous large-scale outflows of on-chain funds from exchanges. Data shows a net outflow of approximately -2,845 BTC across the entire network during this period, with a net outflow of $420,690 ten minutes prior. Notably, the largest net outflows occurred in the $1M–$10M and above $10M segments, indicating institutional and large holder funds flowing from exchanges to cold wallets, rapidly easing spot supply pressure and directly supporting price increases. Meanwhile, ETF fund flows turned into net inflows, boosting buy demand on the spot side, with some institutional funds directly withdrawing coins on-chain after purchase, further reducing circulating supply.

Additionally, active addresses on the Bitcoin network increased week-over-week, total transfer volume continued to rise, and network transaction fees also increased in tandem, indicating renewed market participation enthusiasm and active on-chain behavior. Spot and futures markets show a buying advantage (long positions accounting for 52–53%), with trading volume expanding in sync with the previous hour, suggesting new funds are entering short-term positions and amplifying abnormal movements. Externally, rising geopolitical risks and increased macro market volatility have triggered safe-haven capital inflows, providing additional buying pressure for Bitcoin. Under the resonance of multiple factors, volatility has been amplified.

Caution is needed as current price movements remain constrained within the 73,000–75,000 USDT resistance zone, with ample supply above. Without sustained capital inflows, upward potential is limited. In the short term, close monitoring of ETF fund flows, on-chain capital movements, and resistance breakthroughs is essential. If large fund outflows return to exchanges or inflows slow down, a correction risk exists. Users should stay alert to market volatility risks and promptly observe key on-chain and market indicator changes.
