Goldman Sachs Largest Holder of XRP Spot ETF, Analysts Say “Super Fans” May Dominate

Analysts indicate Goldman Sachs is among the largest institutional holders of XRP spot ETFs. There are also many unpublicized investors, dubbed “super fans” of XRP.

Another Bloomberg analyst, Eric Balchunas, believes most of this capital likely comes from core XRP supporters rather than retail investors.
