I've bought bitcoin and some altcoins. I'm also interested in buying gold and I might buy a small amount. The biggest problem I see with gold is that if you have a lot of it, how do you store it? I doubt I would want lots of it in my house.
Well, if you have a lot of money you must buy bitcoin and gold because both of them will help you to gain much income. Furthermore, some people says that its better to buy bitcoin because there is a chance that the price of bitcoin will increase so that it may lead to high income.
