Germany's insurance giant, Allianz, has snapped up nearly 25% of MicroStrategy's $2.6 billion convertible note offering, signaling a growing institutional interest in Bitcoin. The investment, spread across four Allianz sub-organizations, could impact Bitcoin's price as MicroStrategy plans to use the funds to buy more Bitcoin. This move comes as Bitcoin recently hit a record high of over $99,000, fueling predictions of surpassing $100,000 soon. MicroStrategy's note sale, initially set at $1.75 billion, was increased to $2.6 billion, ultimately raising $3 billion, further boosting Bitcoin's potential rally.
