Following the collapse of the FTX, which impacted valuations and reduced investor interest, Goldman Sachs aims to invest or spend tens of millions of dollars buying crypto companies. Which indicates to me that they clearly see some benefits of blockchain if it's under their control.
I do not think that Goldman Sachs will buy Bitcoin at a cheap price in order to sell it or create an exchange, but rather find an investment opportunity for that, so they will buy Bitcoin, and give users a balance in their account equal to the value of that Bitcoin, shares or any tools with a reference value of the Bitcoin that they purchased.
