Recent discussions, notably sparked by billionaire investor Ray Dalio, have brought the future security and viability of Bitcoin under intense scrutiny. Dalio, who indicates that Bitcoin currently constitutes approximately 1% of his investment portfolio, recently predicted in a CNBC interview that the cryptocurrency could potentially be “cracked” by advanced quantum computing technologies in the future.

This concern about quantum threats is not isolated. Blockchain analytics firm Chainalysis, as reported by U.Today, previously forecasted that Bitcoin’s underlying security could be compromised within a 5–10 year timeframe, urging preemptive action despite no immediate danger. Further emphasizing the need for future-proofing, Solana cofounder Anatoly Yakovenko has advocated for Bitcoin to migrate to a quantum-resistant signature scheme by around 2030 to ensure its long-term resilience. However, such a significant shift would undoubtedly be contentious, as it would necessitate a hard fork in the Bitcoin network.

Conversely, not all experts share the same level of alarm. Blockstream CEO Adam Back has publicly downplayed the potential threat posed by quantum computing to Bitcoin, offering a contrasting perspective in the ongoing debate.

Beyond the quantum threat, Dalio, who first ventured into cryptocurrency in 2021, maintains a broader skepticism about Bitcoin’s future role. He firmly believes that Bitcoin is unlikely to achieve the status of a global reserve currency. His concerns also encompass Bitcoin’s privacy, highlighting its potential traceability, and its inherent regulatory risks, positing that governments could ultimately “shut it off.”

Dalio’s perspective on Bitcoin has evolved over time. While he previously praised Bitcoin’s resilience as a justification for his initial purchase, his more recent comments in a 2024 CNBC interview underscored his skepticism regarding its privacy features and susceptibility to government oversight. Earlier in the same year, he seemed to adopt a more favorable stance, advising investors to allocate up to 15% to either Bitcoin or gold, yet still tempering his recommendation with the recurring prediction that Bitcoin could ultimately be “broken” in the future.
