## 1. Event Overview
From 03:15 to 03:30 (UTC) on May 1, 2026, ETH (Ethereum) experienced a price movement within this 15-minute window, with a return of +0.68%. This article will analyze the cause step-by-step based on on-chain data, trading volume, position changes, capital flows, and other quantifiable indicators, combined with known market events, to clarify the logical inference, identify the specific reasons behind this ETH price movement, and assess related risks.

From 13:30 to 13:45 (UTC) on 2026-04-30, BTC rose by 0.60% within 15 minutes, with a price range of 76112.1 to 76638.3 USDT and an amplitude of 0.69%. This increase was significantly higher than the average of other periods on the same day, indicating that market volatility intensified noticeably and short-term attention increased.
The main driver of this abnormal move is driven by spot buying. On-chain monitoring shows that during this period, net outflows of BTC from exchanges increased slightly, while stablecoin reserves rose at the same time, indicating that new funds entered the market for spot purchases. ETFs continued to record net inflows, and institutional investors increased their holdings via spot channels.

April 30, 2026, 13:30 to 13:45 (UTC), ETH experienced a short-term surge within 15 minutes, with a return rate of +0.54%, price range between 2254.91 and 2272.03 USDT, with an amplitude of 0.76%. Market activity significantly increased, and trading volume rose approximately 18% compared to the previous hour's average.
The main driving forces behind this anomaly are a significant increase in trading volume and multi-point capital inflows. On-chain data shows that ETH trading volume surged sharply in a short period, with capital inflows mainly coming from Layer-2 networks and centralized exchange hot wallets, exhibiting a dispersed distribution pattern.

From 05:30 to 05:45 (UTC) on April 30, 2026, the BTC price fluctuated upward from 75,427.8 USDT to 75,744.6 USDT, achieving a +0.37% return within 15 minutes, with a price volatility of 0.42%. Trading volume during this period expanded compared to the previous period, market attention significantly increased, and short-term abnormal movements occurred.
The main driving force behind this abnormal movement was active buying in the spot and derivatives markets. Taking a major mainstream trading platform as an example, the 5-minute trading volume during this period increased by approximately 18% compared to the previous period, from about 1,200 BTC to 1,420.

From 02:30 to 02:45 (UTC) on April 30, 2026, BTC experienced a short-term decline of -0.66%, with a price range of 75,500.0-76,118.4 USDT and an amplitude of 0.81%. The market as a whole was in a high volatility sensitivity period, and under the background of shrinking liquidity, the price's ability to withstand selling pressure significantly decreased.
The main driving force behind this anomaly was extremely weak liquidity in the spot market. On-chain data shows that the spot trading volume of BTC and mainstream cryptocurrencies dropped to the lowest since November 2023, with active addresses decreasing by 42.6% from the high point in 2021, and on-chain activity

From 02:30 to 02:45 (UTC) on April 30, 2026, ETH’s return within a 15-minute window reached -0.95%. The price quickly dipped to the 2235.97 to 2262.87 USDT range, with a 1.19% swing—market volatility increased significantly.
The main driver of this unusual move is the recent large-scale concentration of ETH transfers into exchanges by multiple institutions, creating potential sell pressure. On April 28, Galaxy Digital OTC transferred 21,369 ETH (about $49.3M) to an exchange; Fidelity transferred to a top-tier trading platform

From 00:30 to 00:45 (UTC) on April 30, 2026, ETH rapidly moved upward within 15 minutes, with a return of +0.43%. The price range was 2254.58 to 2268.84 USDT, with a volatility of 0.63%. Market volatility has increased somewhat, and the short-term rise has exceeded the normal fluctuation range.
The main driver of this anomaly is whale-driven changes in large positions. Over the past 30 days, ETH whales have accumulated a total of 450,000 ETH, roughly US$1.35 billion. Continuous inflows of large funds have led to tighter market liquidity, significantly increasing buy-side pressure, directly pushing the price up.

April 29, 2026, 18:45 to 19:00 (UTC), BTC price had a 15-minute return of +0.35%, with a price range of 75,217.9-75,508.6 USDT, and an amplitude of 0.39%. Short-term volatility increased, market attention clearly rose, and trading volume increased by approximately 12% compared to the previous 15 minutes, indicating genuine capital-driven movement rather than low-liquidity quote fluctuations.
The main driver of this anomaly is the continuous net inflow of ETF funds combined with the market's easing expectations ahead of the FOMC meeting. Over the past 7 days, BTC spot ETF net inflows reached +$933 million, institutional

Within the 18:00 to 19:00 (UTC) time window on April 29, 2026, the ETH yield was -1.83%. The price ranged from 2227.5 to 2285.4 USDT, with an amplitude of 2.54%, and the market saw a clear short-term plunge.
The main driver of this deviation was a sharp surge in ETH net inflows to exchanges. Data shows that during this period, the net inflow of ETH to exchanges reached 98,084.61 ETH. Combined with the 7-day moving average, the net inflow trend noticeably intensified, suggesting pressure from concentrated selling in the market. On-chain tracking shows that Galaxy

From 18:00 to 18:15 (UTC) on April 29, 2026, BTC fell 1.29% within 15 minutes. The price dropped from 76,262.2 USDT to 74,941.2 USDT, with a volatility of 1.73%. During this period, trading volume increased significantly, the order book depth declined rapidly, and short-term price fluctuations were noticeably higher than normal levels, causing a sharp rise in market attention.
The main driver of this unusual move was “giant whales” transferring large amounts of BTC to the exchange and then concentrating their selling. On-chain monitoring data shows that around 3,000 BTC were transferred to a major exchange around 17:55, with the transaction…

From 18:00 to 18:15 on April 29, 2026 (UTC), ETH saw a rapid drop within 15 minutes, with a return of -1.83%. The price range was 2227.5 - 2285.4 USDT, and the amplitude reached 2.54%, indicating a clear increase in market volatility.
The main driving force behind this abnormal movement was the concentrated outflow of major funds from the spot market. On-chain data shows that during this period, there was a net outflow of approximately -11.68M USD from large orders and a net outflow of approximately -31.57M USD from retail funds, both higher than daily average levels. Leading holding addresses showed a clear reduction in positions during the abnormal window, leading to

From 12:00 to 16:00 (UTC) on April 29, 2026, the BTC return was -0.35%, with a price range of 77,310.0–77,597.2 USDT and a volatility of 0.37%. During this period, the price saw a sharp drop, market volatility increased, and bearish sentiment prevailed.
The main driving force behind this unusual move was the steep decline in market risk appetite brought on by the FOMC meeting. On April 29, 2026, the Federal Reserve’s FOMC meeting was held, and the market was highly sensitive to potential changes in the Federal Funds rate policy tone. Institutional investors and large traders generally chose to reduce leverage and sell on rallies.

April 29, 2026, 12:00 to 16:00 (UTC), ETH's return during this time window was -0.47%, with a price range of 2320.57 to 2331.87 USDT, and an amplitude of 0.48%, showing a slight downward trend overall, with limited market volatility.
The main driver of this anomaly is highly consistent with the contraction of on-chain traffic on exchanges and market expectations. On-chain data shows that the average monthly on-chain traffic related to ETH exchanges is below the annual average, reflecting decreased investor activity, with buy and sell pressures becoming more balanced, leading to limited price fluctuations.

April 29, 2026, 15:00 to 15:15 (UTC), ETH's return rate within the 15-minute window reached -0.61%, with the price dropping from 2301.14 USDT to 2283.33 USDT, a volatility of 0.77%, showing a clear short-term pressure phenomenon.
The main driver of this abnormal movement is the concentration of whale addresses transferring ETH to exchanges and quickly selling off. On-chain monitoring shows that whale addresses (single addresses holding over 10,000 ETH) net out approximately 21,000 ETH during this window, a significant increase compared to the previous hour, along with several large individual transactions.

From 15:00 to 15:15 (UTC) on April 29, 2026, the BTC price return was -0.42%, with the price dropping briefly from 76,631.1 USDT to 76,154.1 USDT, a volatility of 0.62%. The market was cautiously sentimented before the macro event window, with obvious short-term selling pressure.
The main driver of this anomaly was the market deleveraging behavior ahead of the Federal Reserve FOMC meeting. April 29 was the FOMC meeting day, and before the interest rate decision was announced, the market was in a wait-and-see mode, with some investors choosing to reduce their positions in advance to avoid risks, leading to short-term selling pressure.

From 13:30 to 13:45 (UTC) on April 29, 2026, ETH fell sharply by 0.54% within 15 minutes. The price dropped from 2307.41 USDT to 2293.5 USDT, with a swing of 0.60%, indicating that short-term volatility increased. The main driver behind this anomaly was the rise in net inflows to exchanges, along with whales continuing to reduce their holdings.
Glassnode data shows that in the 24 hours before and after this period, ETH exchange net inflows reached 98,084.61 ETH (about $420,690), reflecting an increased willingness among investors to realize gains and rising short-term selling pressure. Additionally,
