Goldman Sachs has significantly increased its stake in Bitcoin ETFs, disclosing over $418 million in investments as of June 30. Their holdings include major Bitcoin-related funds such as iShares Bitcoin Trust, Fidelity Bitcoin ETF, and Grayscale BTC. This move highlights the growing institutional interest in Bitcoin and positions Goldman Sachs at the forefront of this trend. Reports indicate that Bitcoin holdings by US ETFs could soon surpass those of Bitcoin's elusive creator, Satoshi Nakamoto, reflecting Bitcoin's increasing mainstream acceptance and institutional adoption.
