BTC 15-minute increase of 0.71%: Large capital inflows and increased holdings by major investors jointly push up the spot price

2026-03-28 13:30 to 13:45 (UTC), BTC’s return rate reached +0.71% within 15 minutes,
with a price range between 66458.1 and 67150.7 USDT,
and a volatility of 1.04%. Short-term fluctuations intensified,
with on-chain and mainstream platform data indicating an increase in market attention,
and significant changes in funding and position structures over a short period.

The main driving force behind this anomaly was a large transfer of BTC concentrated into a major exchange,
with on-chain monitoring detecting a total of 1,800 BTC flowing from personal wallets to the trading platform,
resulting in a temporary increase in the exchange’s BTC balance,
with a net inflow of up to +1,200 BTC. This buying power directly corresponded with an increase in spot trading volume,
with the platform’s spot transaction volume rising by approximately 35% compared to the previous 15 minutes,
and the proportion of large buy orders significantly increasing,
with the average single transaction volume rising from 0.8 BTC to 2.1 BTC. Meanwhile, large holders (addresses holding >100 BTC) saw a net increase of 1.2%,
indicating that institutional-level accumulation and high-net-worth funds entering the market became the core driving force behind the price increase.

Additionally, although the long positions in the futures market saw a slight net increase (about +0.5%),
the overall leverage structure remained stable,
with no large-scale liquidations or extreme position changes observed,
which supports the notion that the buying pressure in the spot market is the decisive factor in this surge. At the same time, other major exchanges experienced a net outflow of approximately -600 BTC during the monitoring period,
with capital flowing across platforms in synchronization with large holder accumulation, slight expansion of long positions, and liquidity pressure,
further amplifying the short-term price upward effect. It is worth noting that there were no significant policy announcements or external sudden events during this period,
and social data showed no abnormal fluctuations; this anomaly was driven by proactive internal capital behavior.

However, caution is warranted, as short-term fluctuations caused by concentrated capital inflows into a single platform may increase the risk of drawdowns;
if large holders reduce their positions or capital outflow phenomena intensify,
the probability of price pressure at high levels will increase. It is recommended to closely monitor key support levels,
on-chain capital flows, and the subsequent changes in positions and large transactions on mainstream platforms over the next 15 minutes,
and to keep a close eye on short-term risks to promptly grasp more information on market anomalies.
