I heard that some research institutions recommend allocating 15% of a portfolio to gold and Bitcoin to hedge against the risk of US dollar depreciation. Is this ratio reliable?

Here's the background: The Federal Reserve's debt and deficits are expanding, and the US dollar's purchasing power is under pressure. In this macro environment, traditional gold hedging strategies have indeed stood the test of time, but interestingly, combining Bitcoin and gold seems to produce more intriguing effects.

There is data supporting this idea. Looking at key drawdown periods over the past decade—2018, 2020, 2022, 2025—these two assets have shown complementary performance during risk events. When one drops, the other may stabilize; the reverse is also true.

Of course, whether 15% is suitable for everyone depends on individual risk tolerance and investment goals. But from an asset allocation perspective, using a small portion of the portfolio to diversify with these two uncorrelated assets makes sense.
