If we look at the overall percentage of risk and potential profit are quite balanced in these two investment options.
Gold has quite good stability and even its price increases slightly over a long period of time while Bitcoin has quite fast and significant movements.
So between these two options I think we should choose the type of investment according to our wishes, if we want profit in the future of course Bitcoin is the choice but if you just want to save it without taking risks then it is better to choose to invest in gold.
Currently, rich people who have more money and have large incomes have chosen both as their future investments by no longer keeping money in their safes except for spare money for living and expenses when they are sick. Because as you said, almost everyone wants to have greater profits through their investments and also wants to save assets that do not experience inflation such as gold, so it would be quite appropriate if rich people choose both as their current and future investment assets.
