It's up to you, but if you choose to buy gold.. you might end up selling it again or find yourself at the nearest pawnshop, or if you love collecting gold then it can juts put it in a much secure area of your house. ahaha
But when you choose bitcoin, then... there is a great possibility that you'll get much more than you have invested. It's just a matter of patient, hard-wok, and strategies.
I think most likely it will. Maybe not bitcoin, but the crypto currency will replace paper money. And it will be good if we have an opportunity to make good money. Because if there is no money, then it is not important whether it is a dollar or bitcoin.
