Gold is boring. Sure you can always have a peace of mind knowing that gold's network effect is simply too strong to ever disappear, but if you want to get rich in your lifetime you will never make it with gold. You have a million more chances making it big by holding Bitcoin, so I recommend that if you want big changes, you gotta go for Bitcoin and forget about gold
Everything turns quite interesting if you look at gold derivatives like futures and options

Well, yes, physical gold tends to move in a less volatile manner than BTC (ex. today, gold down over 2%). Gold may turn out to be interesting in the future however. If an aversion to currency develops (for various reasons), then gold could move sharply up. Yes, with futures and options you get even more "juice" (leverage).
Bitcoin has been rather well over the past week.
I HODL both, a diversification that I am very happy with. As I mention often, there is no need to choose, own both! BTC and Au move somewhat independently, and so both assets are good (and independent of stocks and bonds).
