Although industry bulls may appreciate #BlackRock's entry into the market for crypto-related exchange traded products, it could cause problems for one of the biggest market participants.

A number of asset management companies are eager to launch a spot-based product on the market, including the business, which last week filed a filing with the U.S. Securities and Exchange Commission for a new trust linked to the biggest #cryptocurrency. Another is #Grayscale, which has long provided a variety of trust goods.

The products offered by Grayscale trade over-the-counter and may not always mirror the price of the underlying asset, unlike #ETFs, which are traded on a national securities exchange. Even so, it has been able to charge #traders a sizable fee.
