From the chart you shown as I go through the links also have overview of the yearly high of Gold, the margins between Bitcoin can't be compared in any way, Bitcoin is far better.

Though Bitcoin stand to be the best but investing on gold is not bad as it may be a matter of choice.

But I see Bitcoin as investment that gives better profit that the gold if you invested during the Bear and hold long time and sell during the bull the profit can't be compare with gold
