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.
If you are rich and you have a lot of extra money then you must invest in gold because it is a good way to secure your money and slowly grow it because gold is one of the safest investment that you can made and it is not hard to have that because there is a lot of seller of gold and also it is easy to secure it by just having a secured vault in your house.
