Bitcoin's BTC$80,666.31 recent rise above $80,000 was led by leveraged trades and lacked strong participation from the U.S.-based investor pool, which typically plays a key role in sustaining bullish trends.

Their underperformance of U.S. spot buyers relative to their global peers is evident in the Coinbase Premium, which measures the price gap between bitcoin on Coinbase and on offshore exchanges, has stayed negative since late April, per CryptoQuant data.

A positive premium typically signals U.S. institutional demand outpacing the rest of the world's spot buying, since Coinbase is the primary on-ramp for American capital. A negative premium means the opposite: offshore traders are paying more for bitcoin than U.S. investors are willing to pay, driving prices higher.

That divergence has now held through a 5% rally. Bitcoin BTC$80,666.31 traded above $82,000 on Tuesday before slipping back below $80,000 after Wednesday's hot producer price index print, with the cryptocurrency changing hands near $79,500 at the time of writing.

The price action played out entirely above the $80,000 level at which the Coinbase Premium turned negative. CoinDesk first flagged the negative flip in the premium on April 29 alongside a $5.97 billion spike in realized losses from underwater holders selling into the rally.
