Gold has intrinsic value. Bitcoin has none. Gold hasn't lost a third of it's value in the last month or so. Bitcoin was under $700 a year ago. There's no reason why it couldn't drop to $700 again. A year ago gold was at about $1340. It's at $1225 now. Gold has a 5000 year history of being money. Bitcoin, at 7 transactions per second, it's even a real currency.
