The US-driven momentum that fueled April's price surge is losing steam. The Coinbase Premium, which measures the difference between the price of Bitcoin on Coinbase and offshore exchanges, has turned negative for the first time since early April, according to CryptoQuant data.

This metric had consistently shown a positive trend from April 8 to April 22, during which time Bitcoin's price rose from $66,000 to a local high of nearly $78,000. However, the premium peaked around April 22 and has since declined.

As Coinbase is often used as a proxy for US institutional and dollar-denominated flows, a persistent negative reading suggests that American investors are now paying less than the rest of the world, indicating either more aggressive selling or a lack of buying interest. On-chain data reinforces this narrative, with the 7-day sum of Bitcoin Realized Loss spiking to $5.97 billion on April 24 as Bitcoin traded near $78,000. This realized loss is only recognized when holders sell coins below their original purchase price. The fact that the selling occurred near $78,000, with a total value of almost $6 billion, implies that the sellers were buyers at higher prices, likely between $80,000 and $95,000 during late 2025 and early 2026.

They seem to have used the April bounce as an opportunity to exit rather than reenter the market. The combination of these two datasets suggests that US institutional buyers are slowing their purchasing activity through Coinbase, while holders are increasing their selling.

Bitcoin was recently trading around $76,000. Going forward, traders will be watching to see if the Realized Loss metric continues to decline as the supply of underwater coins is worked through.

The reading has already decreased from its April 24 peak to $4.7 billion by April 28, indicating that the seller cohort may be dwindling.
