If i had to choose between these two i would use only the gold off course but if i had to choose to keep them both i would say we need to spent more gold and invest with more bitcoins off course.
Although bitcoin and gold have a lot of similarities they also have a lot of differences, that is why I see gold more as a store of value, while I see bitcoin more as an investment
some people thinks gold as a store of value , but you know there a lot of people use bitcoin to store value too as the price will continue to rise , and sometimes they think both store of value and investment too.
it is really hard actually to understand bitcoin but so far people should pick bitcoin with all advantages.
