Are you investing, speculating, or preparing? None of these are wrong, but they are done for different reasons.
Even if cryptocurrencies are more profitable than gold, that is true only when it's time to cash out.
Then there is the need for protection. When we lose electricity for long periods of time-- and it can happen-- your cryptocurrency has as much worth and value as a broken brick. In this situation, you want to be the one with gold.
Think of the 2 assets as complimenting each other and protecting you in 2 ways. Crypto gives you insane gains if you HODL long enough, and gold protects your investment portfolio when nature or astral bodies wreck your area.
