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.
Yeah its an smart decision to invest in bitcoin as we have opportunity to make quick profits which gold will never allow us, so people who can afford to take risk they will invest in bitcoin.
