Goldman Sachs (GS.N) plans to spend tens of millions of dollars to buy or invest in crypto companies after the collapse of the FTX exchange hit valuations and dampened investor interest.

FTX's implosion has heightened the need for more trustworthy, regulated cryptocurrency players, and big banks see an opportunity to pick up business, Mathew McDermott, Goldman's head of digital assets, told Reuters.

"We do see some really interesting opportunities, priced much more sensibly," McDermott said in an interview last month."It's definitely set the market back in terms of sentiment, there's absolutely no doubt of that," McDermott said. "FTX was a poster child in many parts of the ecosystem. But to reiterate, the underlying technology continues to perform."

While the amount Goldman may potentially invest is not large for the Wall Street giant, which earned $21.6 billion last year, its willingness to keep investing amid the sector shakeout shows it senses a long term opportunity.
