BItcoin is more popular in online market, but for real market (offline) gold is number 1, to get fast growing bitcoin is the best choice

We are already heading towards more capitalization with the stability of markets going on near $600.
Both will have higher value in the future because both bitcoin and gold is a limited resources. So there is no bad choice between the two. If you can invest in both of them, then it is better. It does not matter which is number 1, what matters is that you can make profit from them.
