On March 5th, Dalio, founder of Bridgewater Fund, said recently that the current global monetary system is based on debt, and governments may devalue their currencies through inflation or low interest rate policies. Investors should consider whether there is a relatively stable alternative currency that does not rely on debt. He believes that bitcoin may be one of the candidates, and may even play an important role in the future, but stressed that "money is essentially debt", and the real alternative currency still needs to be further explored. Mr. Dalio pointed out that Bitcoin's advantage as a safe haven asset was that it was liquid and unlike real estate, it was not fixed in place and therefore more difficult to tax or confiscate. However, he also stressed that diversity and soundness of investments were more important. Asked about his views on gold, Mr. Dalio said he was more bullish than before but advised investors to exercise restraint. He believes the future is full of uncertainty and investors need to build a diversified portfolio to deal with it. He recommends a "prudent" allocation of 10-15 per cent to gold, which is both protective and avoids over-reliance on a single asset. He stressed that a reasonable allocation of assets is an important strategy for dealing with future uncertainty.
