According to CoinDesk, Bitwise is merging its three futures exchange-traded products into one fund. The new fund, called Bitwise Trendwise Bitcoin and Treasuries Rotation Strategy ETF, will rotate between 100% crypto futures contracts and 100% U.S. Treasuries.

Bitwise said the switch will take place on Dec. 3. The firm launched a spot bitcoin ETF earlier this year that holds $2 billion in the cryptocurrency.

Investor interest in the three legacy products waned due to the launch of spot Bitcoin and Ethereum ETFs, prompting the company to merge them into a new product.

The new fund will better manage volatility in the crypto market by rotating between crypto futures contracts and U.S. Treasuries based on market trends. The new fund’s expense ratio will be 0.85%.
