Billionaire investor Ray Dalio has recommended that investors allocate up to 15% of their portfolios to a combination of Bitcoin and gold as a hedge against rising U.S. government debt and economic uncertainty. Dalio, known for his macroeconomic expertise, suggests this allocation to protect against fiat currency devaluation amid what he describes as a U.S. 'debt doom loop.' While he favors gold over Bitcoin, Dalio acknowledges Bitcoin's growing role as a store of value, especially for younger generations, and notes that markets have yet to fully price in the risks associated with the U.S. debt crisis. This recommendation marks a significant increase from Dalio's previous Bitcoin allocations, which ranged from 1% to 3%, reflecting his evolving stance on cryptocurrencies as part of a diversified long-term investment strategy.
