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.
If you have a lot of money you must buy bitcoin and gold because both of them will help you to become rich in the near future. In addition to that, I prefer to buy bitcoin because I can use it in different kind of transaction unlike gold and I think it will become our future money.
