Bitcoin (BTC) faces rising sell pressure as key on-chain indicators flash bearish signals. The Coinbase Premium Index has turned negative for the first time in three weeks, suggesting a return of selling activity from US-based investors, particularly institutional players. According to data from CryptoQuant analyst Maartunn, the Coinbase Premium Gap — which measures the price difference between BTC on Coinbase (USD pair) and Binance (USDT pair) — broke a 20-day positive streak and plunged into negative territory on April 28-29, 2026.
The shift coincides with Bitcoin slipping below the $77,000 mark, currently trading around $76,500, down 1.7% in the last 24 hours. The negative premium indicates that US whales are applying higher selling pressure compared to global traders on Binance, reversing the buying dominance seen throughout most of April. This pattern has historically correlated with price weakness, as was observed last month when an extended negative phase kept BTC under pressure.
On-chain data further reveals that weekly realized losses have climbed to $829 million, while realized profits stand at only $566 million, reflecting reduced holder conviction after recent price swings. Binance derivatives data shows $828 million in net taker sell volume over 24 hours, with the taker ratio falling to 0.89 — a level previously associated with short-term reversals. Order flow data also shows reduced aggressive bids during US trading sessions, reinforcing the divergence between spot demand and futures positioning.
Market structure indicates that support near $77,300 and the key trendline have been lost, with traders now watching the $74,500 to $75,500 range as the next critical liquidity zone. The heightened sensitivity to macroeconomic events, including the upcoming Federal Open Market Committee (FOMC) meeting, could amplify volatility. While some analysts interpret current conditions as a phase of temporary exhaustion rather than structural breakdown, the direction likely depends on whether US demand stabilizes and liquidity returns to major exchanges.
