At the same time, the broader market is seeing developments that could impact investor behavior.

Nasdaq has filed with the U.S. Securities and Exchange Commission to list Bitcoin Index Options, which will track Bitcoin’s price via the CME CF Bitcoin Real-Time Index. This move, pending regulatory approval, aims to improve market transparency and offer investors better tools to manage and hedge their crypto positions.

Additionally, CME Group is planning to introduce smaller-sized Bitcoin futures contracts, which could appeal to retail investors.

At the time of writing, Bitcoin (BTC) was down 5.8% over the past day, trading at $59,160, per data from crypto.news.
