Mark Hackett, head of investment research at Nationwide, said that Bitcoin and gold help diversify traditional portfolios, and in addition, both assets can help hedge against a depreciating dollar. Mark Hackett explained, "Investors concerned about stock valuations, fiscal debt, and interest rate pressures may benefit from gold positions, but with gold near all-time highs, exposure to the asset should be modest." On the other hand, Bitcoin's returns have been impressive, mostly moving in sync with the stock market, especially technology stocks. Mark Hackett noted that "investors with higher risk tolerance and longer time horizons can benefit from exposure." (Morningstar)
