Billionaire investor Ray Dalio recently shared his predictions on Bitcoin's future, expressing concerns about the potential threat of quantum computing. During a CNBC interview, Dalio suggested that Bitcoin could eventually be 'cracked' by quantum advancements. Despite this long-term skepticism, he revealed that Bitcoin currently constitutes approximately 1% of his investment portfolio.

Dalio's views on Bitcoin's security and future as a global currency are echoed and contrasted by various figures in the cryptocurrency space. Blockchain analytics firm Chainalysis has previously warned that Bitcoin's security protocols might be compromised within 5-10 years, urging proactive measures despite no immediate danger. Similarly, Solana co-founder Anatoly Yakovenko advocated for Bitcoin to transition to a quantum-resistant signature scheme by around 2030, acknowledging that such a significant change would necessitate a controversial hard fork.

Conversely, Blockstream CEO Adam Back has downplayed the immediate threat posed by quantum computing to Bitcoin's integrity, offering a differing perspective on the urgency of these concerns.

Beyond the quantum threat, Dalio has consistently expressed skepticism regarding Bitcoin's long-term viability as a reserve currency. He has raised points about its traceability and, in a 2024 CNBC interview, voiced significant concerns over Bitcoin's privacy and inherent regulatory risks, even suggesting the possibility of government intervention to 'shut it off.'

Dalio's stance on Bitcoin has seen an interesting evolution. While he first entered the crypto market in 2021, praising Bitcoin's resilience as justification for his purchase, his more recent comments reflect a blend of cautious optimism and persistent skepticism. Earlier this year, he appeared to adopt a more favorable outlook, recommending that investors consider allocating up to 15% of their portfolios to Bitcoin or gold. However, this advice was still tempered with his recurring prediction that Bitcoin could ultimately 'end up being broken in the future.'
