Recently, a global equity strategy head at an investment bank made a bold move—completely cleared 10% of Bitcoin positions from their own model portfolio. The reason sounds a bit hardcore: the development of quantum computing could pose a threat to Bitcoin's cryptographic security. This move has sparked quite a bit of discussion in the market. The impact of quantum computing on blockchain security has always been a hot topic, but when institutions actually start taking action, it makes people reconsider Bitcoin's long-term security architecture. However, some also believe that the blockchain community should prepare technically before the quantum threat truly matures. This reduction is more about proactively addressing potential risks rather than indicating that Bitcoin currently has major issues.
