Gold or bitcoin depends on your goals, if you want a safe, low volatility investment and don't need a lot of return, then gold is clearly the better choice. But if you are looking for an investment with a high return and are willing to take all risks, then bitcoin will be the perfect choice over other investments. It would be great if we knew how to diversify these two investments, both minimizing risk and providing the highest return.
Investing in gold should probably be a smaller part of our investment portfolio, since this investment is aimed at preserving our savings, rather than making big and quick profits. Bitcoin can give great profits, but there are also more risks, so everyone must decide for himself how much and in what he wants to invest. Also, there should always be free funds to replenish your portfolio in case of large market crashes.
The higher the risk, the greater the reward; it is up to the investor to decide which route to choose. Some will say the high reward because they are not considering the risk that it involves, which is why they lose big because they do not consider both sides since they did not conduct research. Typically, the strategy of the investors I've noticed is to allocate a portion of their money to bitcoin and the remaining percentage to other low-risk, stable assets such as gold. Try to research first and think about which option is best for you, then run calculations and what-if scenarios to help you decide.
