You do know there are other ways to invest.. Not just bitcoin or gold, I'd suggest talking to a finical adviser about your investment options.
True there are many ways to invest, we can put it in, traditional business, franchising business, jewelry, apparels, grocery, or gold. any of them that we are going to invest in saving money is just secondary for the investment because in this aspect it produce money for us to do how to save money. this is what I understand in the question.
