Go with both.
However if you wanna be  very flexible and quick in leaving when shit hits the fan(economy down, bail ins, dictatorship,gold gets mostly banned, cash only exist in small bills,) Bitcoin will have some advantages compared to gold.
Let's say you want to migrate to another country in oversea somewhere, hiding gold in your luggage would be a bad option if you own a bit more of it.The same goes for cash.So Bitcoin would be the right choice here.
