About the future we cannot be 100% sure but the philipma1957 data reflect a clear trend. What is likely, in all likelihood, is that the future will resemble the past and bitcoin will continue to outperform gold. The opposite is not impossible but unlikely, not only because of history, but also because of the intrinsic properties of bitcoin, which for example make it much easier to hide and transfer, faster, etc. Another reason is the general shift of the world to digital.
