I will hold both gold and the bitcoin. I will hold them with ratio of 2:8 in favour of bitcoin as it will rise in value faster.
It is better to diversify the investments in different products. But for me I choose Gold over bitcoin as Gold have many satisfied customers who have invested in the past and have earned good profits too. So I would choose to invest in Gold rather then bitcoins.
That's true gold is safer in compare bitcoins and people have more faith in gold as they are using it since long time and they can earn good profits from it if they hold for long term.
