I think a 1 single Gold is still much more valuable than 1 single Bitcoin but maybe in terms of the growth through the years the real winner is Bitcoin and no doubt about that because Bitcoin is not yet 10 years in existence.
As Gold is tangible while Bitcoin is not it is in different league but with a certain amount of value you can differentiate them but please never compare them and tell that Bitcoin defeated gold.
gold have its own features i think most of the gold is now using for some decoration of men women in the world and have now very low contribution in the economy as the world is running through transaction while a common man cannot do transaction with gold as he she will use it for jeweler and the common man need some source of money like paper currency or BTC to make transaction like purchase foods etc for himself.
