Kevin O’Leary says quantum risks are capping institutional Bitcoin exposure near 3% as BIP-360 proposes a new P2MR output to harden the network’s security.

Billionaire entrepreneur and investor Kevin O’Leary said security risks posed by quantum computers are preventing institutional investors from expanding their Bitcoin holdings, according to recent statements.

O’Leary stated that institutions remain reluctant to increase Bitcoin (BTC) allocations above 3% until quantum-related security concerns are resolved. The general approach among institutional investors reflects “cautious waiting,” according to O’Leary, with long-term funds and large portfolio managers seeking greater clarity on how Bitcoin’s security architecture will be protected against quantum computing threats.

Christopher Wood, Jefferies’ Head of Global Equity Strategy, recently removed a 10% Bitcoin allocation from his model portfolio, citing uncertainties surrounding quantum security as the reason for the decision. The move signals that quantum computing threats to cryptocurrency security may be receiving increased attention from institutional investors.

Bitcoin developers have added a proposal designated BIP-360 to the official Bitcoin Improvement Proposal GitHub repository, entering the evaluation process for potential future implementation. The proposal aims to address quantum security concerns by introducing a new output type called P2MR, which would reduce exposure of the existing public key architecture and create a more resilient structure against quantum attacks, according to the proposal documentation.

The developments indicate growing institutional focus on quantum computing as a potential security challenge for Bitcoin’s cryptographic infrastructure.
