BlackRock, the world's largest asset manager, is set to buy spot bitcoin exchange-traded products.

The firm's inclusion of bitcoin reflects a growing trend of integrating cryptocurrency into major financial portfolios.

Analysts predict that bitcoin's value could more than double, surpassing $138,000, influenced by investments from financial giants.

The firm's interest in bitcoin products for its multi-billion-dollar funds may further fuel the cryptocurrency's price surge.

Bitcoin's price currently stands at approximately $71,700, having increased by 2.5% today and over 10% in the past week.
