The bitcoin price rally that occurred on Sunday night has lost momentum near $79,400, showing signs of exhaustion, with multiple indicators suggesting potential short-term weakness as the price falls back to around $77,000. The Coinbase premium index has turned negative for the first time since April 8, according to data from Coinglass, indicating a shift in demand from US investors.

The index, which measures the price difference between Coinbase and offshore exchanges like Binance, has flipped into negative territory at -0.04% after a 14-day stretch of positive readings, the longest since October. This change suggests that US institutions are no longer driving the price upward, leaving the market more dependent on offshore flows.

Historically, a negative Coinbase premium has coincided with price pullbacks or consolidation. Meanwhile, the large Bitfinex whale, a closely watched entity for market direction, remains near its cycle peak in terms of long exposure, with current holdings at 79,342 BTC, just shy of the 80,100 BTC high.

This entity typically reduces its position once a local bottom is confirmed or when there is clear upside momentum. The fact that exposure remains near the cycle peak despite the recent push toward $79,000 suggests a lack of short-term upside, increasing the risk of a price decline. Furthermore, bitcoin failed to reclaim the short-term holder realized price (STHRP) at $79,200, which represents the average on-chain acquisition cost of coins held for fewer than 155 days. This cohort tends to be more reactive to price swings, and the longer the price stays below the STHRP, the more likely recent buyers are to exit, putting further pressure on the price.

Finally, with the flagship Bitcoin conference underway, prior gains have already begun to fade, and if historical patterns hold, further downside may follow.
