I think both bitcoin and gold are good investment and one should not ignore other at the cost of one.If you are travelling,bitcoin paper wallet is better to carry but make sure it is not illegal in your visiting country and there are merchants that accept bitcoin
For me they are really both good type of investments but of course gold is going to be on the first list. As the people are really thinks that gold has the supreme value of all time. But I will going to go with bitcoin as I can see it is going to be the next gold or let's say that this is going to be the digital gold of the modern era.
