Gold has proven its worth for a long time and I don't think that is going to change in the near future. Wherever you go, gold is a relatively known commodity that commands a great value. To compare it with bitcoin which is still at its early stages of development would be a little off. We all know that both has value right now but bitcoin is pretty much still an unknown currency, that is to the general masses.
I think it's a good thing that we're living a life where bitcoin is still in its early age. That means if bitcoin is a success in the far future and you've invested today, you'll be one of the rich people of the world. I think gold is valuable too and can be made profit of when you buy and sell it in small scale. But I don't think gold is for everybody. I mean, only rich people make good amount of money by holding gold because they hold a lot of it. But in bitcoins, even peasants (like me) can earn from it.
