Bitcoin gives more profit because its price changes daily and there are many people who trade it thats why bitcoin is good than gold.
I agree with your statement that Bitcoin is more volatile when compared to gold. But how is it going to bring in the profits, unless you are a short seller? I know large number of Bitcoiners, who lost their investment after the prices crashed in 2014. They bought the coins for $800 or $900 in late 2013, and till now they haven't got the ROI.
After long time seeingyou @Bryant coleman, I would personally choose bitcoin because i believe it has a lot of potential than gold. however i know all of my friends would choose gold because they'd see it as a more tangible item and bitcoin is have big price value in the market than gold in future.
