my choice is bitcoin.
Its a good choice as of now it is really the easiest way to invest. Gold investing needs some documents to be filed or you might buy it at a store or a person who sells fake golds. So it is better with bitcoin now just buy on a trusted website.
WHere did you find that? I have bought some gold (over mail delivery a few months back) no ID was asked from the seller (a British company).
But if you look at the current price going down again, and looking towards the price a few months back (increasing) bitcoin seems to be perfect for the long term, but not good for the short term. In times you need money you will make a lost on your bitcoin investment, while gold would hold more value. For this reason I prefer gold.
