The remaining 80.7% of spot ETF holders remain unidentified.

Summary
On January 11, 2024, the U.S. Securities and Exchange Commission (SEC) approved the listing of 11 spot Bitcoin ETFs, a landmark moment for the digital asset market. The approval of Bitcoin ETFs and other crypto-related ETFs has undoubtedly opened the door for traditional investors to enter this emerging market.
Since ETFs listed on exchanges are regulated by the SEC, investing in Bitcoin via ETFs carries lower risk compared to direct ownership. Amid global geopolitical instability and expectations of Fed rate cuts, spot Bitcoin ETFs have become attractive investment vehicles for traditional financial institutions.
However, if only 20% of institutional holdings are publicly disclosed—as suggested by 13F filings—who owns the remaining 80%? Moreover, as massive capital flows into these dominant financial products, could this drain liquidity from primary and secondary markets, potentially starving new projects of attention and funding?
