Bitcoin can beat gold in terms of its price or value but due to its volatile nature, it can never replace gold as a safe haven. So if what you are looking is a more profitable long-term investment, bitcoin would be the best choice, but if you mean to say a fixed and stable asset all throughout its existence, gold would own that position.

However, to make you get rich quickly and highly profitable in the long run, invest in both. Diversify your investment, so that you will gain multiple profits when all your investments have paid off.
