Can I choose both, I would chose 50% on bitcoin and 50% on gold. hehe, it's better to be safe than sorry. But if you really want me to choose one, I could choose bitcoin. 
Yes, we should choose both, the good and wise thing is to divide the money into many investment places and I think gold and bitcoin is a good investment and have a clear prospect in the future.
Gold doesn't give you a good income compared to bitcoin. It's for rich people. Regular people cannot buy gold to make profit from it. Bitcoin is more profitable compared to gold and it's better in terms of profit.
