I have the majority of my investment portfolio in bitcoin but have also diversified into some physical gold holdings. The two investments are very different. You mention bitcoin is being seen as gold and this is only partially true. The gold price is determined on the COMEX (commodity market) which is controlled by the banks and fed. It is in their best interest to make gold seem like an unworthy investment and "gold bugs" are convinced that they are manipulating it. Gold is seen by many as a hedge against crashing markets, such as happening in China, but it really isn't unless you're in China itself and trying to just retain consistent value. It can only act as-if in a free market if the Fed, major banks, and/or a complete meltdown happens. It is a good place the store wealth, but you're at the mercy of the people you're trying to protect yourself from until they bust. Gold also has a history of being confiscated by the US Treasury, so that's another threat.

I personally like bitcoin right now as my primary investment choice because, although there is manipulation, it is the most transparent store of wealth and market that I can think of. I wouldn't touch the stock market with a giant stick right now. Holding gold will only show true gains if the COMEX has a major issue that realizes the true value of actual gold in vaults and gold in the world. With bitcoin, all of this is transparent. We know exactly how many there are, how much is being mined, and we basically know the transaction volumes of it. It's as close to a free market as anything else in this current economic crisis beginning to unfold. Bitcoins biggest downsides (to me) are misinformation, lack of general and mainstream education, potential scalability issues remaining unsolved, and political issues. These pretty much don't effect my decision because although the market is small, the price is low enough to be a major player in 2016 for the individual investor still on a percentage basis.

I see gold as a solid place to hold wealth, not an investment, and bitcoin as a good storage of wealth as well (with unique problems) but with explosive potential upside.
