Hands down bitcoin. 1 BTC will be worth more than 1 ounce of gold soon 
Yeah but gold is safe so it depends all on how much money we are talking about. If it's about millions then obviously i'll put it in gold but if it's not that much money i'll put it into bitcoin to try and make it more via that route.
At the moment I would pick bitcoins.
Simply because gold is for me a long term investment, and at the moment I'm not searching something like that.
I can sell my bitcoins easily with my computer on every exchange, I don't think it's that simple with gold.
