Yes, it does already more valuable than gold. Seeing the market price increase of bitcoin from the day it was created to gold which price to compare should be the day that bitcoin too was created had a huge difference. Bitcoin has been doing a lot of increase than gold.

In my opinion Gold too is valuable but for now we can't deny the fact that bitcoin is really good compare to gold. Many gold investors now also transfer in investing bitcoin and other cryptocurrency the same as with the stock market investors that are now investing in cryptocurrency.
