Bitcoin's Coinbase Premium has turned negative for the first time since early April, indicating a shift in U.S. investor behavior. The premium, which measures the price difference between Coinbase and offshore exchanges, had been positive from April 8 to April 22, coinciding with Bitcoin's rise from $66,000 to nearly $78,000. However, it has since flipped negative, suggesting U.S. investors are either selling more aggressively or not participating as actively. Simultaneously, Bitcoin's Realized Loss 7-day Sum spiked to $5.97 billion on April 24, as the cryptocurrency traded near $78,000. This metric, which tracks the dollar value of coins sold at a loss, indicates that sellers had previously bought at higher prices, likely between $80,000 and $95,000. The decline in the Realized Loss metric to $4.7 billion by April 28 suggests a reduction in selling pressure as the market adjusts.
