Not directly, sure. The low interest rates, and the overall increase in money in the system, made VC investing less risky compared to other options. Now that changes.
Interest rates are for banks borrowing from the Fed, affecting interest rates on loans issued by banks, and the rate of bank lending. But I don’t think VCs fund themselves by taking bank loans.
These crypto companies are primarily capitalized by VC and selling crypto.
Alternative "assets" like crypto gained more credence when rates were low. Bond returns in such a regime were not attractive, equity markets rallied to elevated levels, and there was little incentive for debt issuers to use free cash to pay down debt that could be rolled out into perpetuity.
The Fed essentially held the cost of money near zero and that had far-reaching effects.
