At the moment bitcoin is at position to achieve better price then gold so I would choose bitcoin at the moment. And it's also good long term investment just as gold, something that will have even bigger value in the future, so invest in bitcoin and if necessary you can always turn it into gold.
I don't want to say that bitcoin will surpass gold's value since they are both good type of investments. But I will really go for bitcoin.
I don't have gold or something that has gold, I always wanted to have gold but I accept the fact that in my situation.
Bitcoin will be the dominant.
