I would always go with holding Bitcoin because that is what I know and what I am familiar with and I do not no a thing about gold.
I think that I am going to search some things about gold and maybe invest in it as well.
Investing in gold is relatively straight-forward. It is not as complex as purchasing equities or mutual funds. Also it is not as difficult as investing in real estate or farmland (which requires a lot of paper-work). Only a few things should be checked before purchasing gold - such as the quantity of purchase, storage and long-term target.
