Signs of exhaustion are emerging in Bitcoin’s rally, with major indicators turning negative.

Cooling U.S. demand, heavy Bitfinex whale positioning, and a key on-chain rejection level are pointing to possible near-term downside for bitcoin as the Las Vegas Bitcoin Conference begins.

Bitcoin’s rally lost steam Sunday night after failing to sustain a move above $79,400, with the price slipping back toward $77,000. The pullback comes as multiple indicators begin to signal weakening momentum following the recent advance.

A notable shift is visible in the Coinbase premium index, which has turned negative for the first time since April 8, according to Coinglass data. The reading of -0.04% breaks a 14-day run of positive premiums—the longest streak since October—that had reflected steady buying pressure from U.S. investors and supported bitcoin’s climb from $66,000 to nearly $79,000.

The index measures the price gap between Coinbase, often used by U.S. institutions, and offshore exchanges like Binance. A move into negative territory suggests that U.S.-based demand is cooling, leaving the market more reliant on offshore activity. Historically, such shifts have aligned with periods of consolidation or short-term declines.

Meanwhile, a closely watched Bitfinex whale remains near peak long exposure, holding 79,342 BTC—just below the cycle high of 80,100 BTC. This participant typically trims positions once a local bottom is confirmed or when strong upside momentum develops. The continued high exposure despite bitcoin’s recent rally signals limited confidence in further gains and increases the likelihood of a pullback.

On-chain data also adds to the cautious outlook. Bitcoin has been unable to reclaim the short-term holder realized price (STHRP) at $79,200, a key level representing the average cost basis for coins held under 155 days. As long as the price remains below this threshold, newer investors may be more inclined to sell, creating additional downward pressure.

Adding to the uncertainty, the Bitcoin Conference is now underway, and past events have often coincided with fading price momentum. Early signs suggest that this pattern may be repeating, with the market struggling to maintain its recent gains.
