I don't know if a collapse will happen this year already, but it is a fact that the current financial system is heading to a dead end. Printing money and raising dept can't go on forever.

I think IF the dollar collapse, bitcoin will be a much better asset to own than gold because people can use it to buy goods. Businesses will remark that they can remain selling goods ones they accept bitcoin and the bitcoin economy will boom.

If you want to buy something with your physic gold you will have to sell the whole unit for fiat, before you are able to purchase something. The rest of the value that you don't spend immediately will devalue quickly. Bitcoin is very dividable so you don't need fiat as medium of exchange.
