Bitcoin prices may be higher as of now and in future as well, but I don't think it will overtake the popularity of gold investments. Most of the governments invested in these gold but none the governments invested in bitcoins yet. Bitcoins are popular only in gambling and porn industry now, and only a few % of people are using bitcoins as of now in the world. So it is not so easy to overtake gold.
Exactly! overtaking gold by bitcoin will not be easy as gold is backed by Governments who will not easily back bitcoin as bitcoin is totally out of their control. The entire bitcoin beats gold and bitcoin price is more than gold is just some quotes made up by some writer to grab attention for his/her article. That's it! Bitcoin still has a long way to go if it wants to beat Gold fair and square.
