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.
Maybe that's the difference between gold with bitcoin and altcoin, if you prefer to buy lots of altcoin then you can be invested to multiply from the purchase, if you buy more gold then at least you are too dizzy to think of gold for fear of missing and so on, and also gold can not be duplicated if it is in your hands unless it is sold by way of own profit.
