Bitcoin’s rally is losing momentum as key indicators begin flashing bearish signals.

Cooling U.S. demand, elevated whale positioning on Bitfinex, and a key on-chain rejection are signaling potential short-term downside for bitcoin as the Las Vegas Bitcoin Conference gets underway.

Bitcoin’s rally lost momentum late Sunday after failing to break above $79,400, with prices slipping back toward $77,000 and showing early signs of fatigue. A combination of weakening demand indicators and technical resistance suggests the market may face near-term pressure.

One key signal is the Coinbase premium index, which has turned negative for the first time since April 8, according to Coinglass. The drop to -0.04% ends a 14-day streak of positive readings—the longest since October—that had reflected steady buying from U.S. investors and helped drive bitcoin from $66,000 to nearly $79,000.

The index tracks the price difference between Coinbase, widely used by U.S. institutions, and offshore exchanges such as Binance. A move into negative territory indicates fading demand from U.S. buyers, leaving the market increasingly dependent on offshore flows. Historically, such shifts have coincided with periods of consolidation or price pullbacks.

At the same time, a closely watched Bitfinex whale remains positioned near peak long exposure. Holdings currently stand at 79,342 BTC, just below a cycle high of 80,100 BTC. This entity typically reduces exposure once a local bottom is established or when strong upside momentum emerges. The persistence of such elevated positioning, despite bitcoin’s recent rally, suggests limited near-term upside and raises the risk of a reversal.

Further adding to the cautious outlook, bitcoin has failed to reclaim the short-term holder realized price (STHRP) at $79,200. This metric reflects the average acquisition cost of coins held for less than 155 days—a group often more sensitive to market swings. Continued trading below this level increases the likelihood of recent buyers exiting positions, adding downward pressure.

Finally, the start of the Bitcoin Conference itself may weigh on sentiment. Previous events have often coincided with fading gains, and early signs suggest the current rally may be following a similar pattern.
