Bitcoin’s Fate Still Tied to ETFs, Not Corporates, K33 Report Finds 

Despite a slowdown in Bitcoin trading activity and rising geopolitical risks, spot Bitcoin ETF flows remain a dominant force in price movements, according to Vetle Lunde, Head of Research at K33.

In a report published Tuesday, Lunde pointed to a strong 30-day correlation between ETF inflows and BTC returns, with an R² of 0.80—indicating ETF flows explain approximately 80% of price variance over that period.

Over the past month, Bitcoin ETFs added 13,000 BTC, marking the weakest 30-day inflow since April 23, and closely mirroring recent price action.
