Property is subject to bubbles, and in almost any economic recession prices of real estate tend to fall (demand drops, and sellers/supply grows). Bitcoin is a far better asset hedge, as it possesses almost every property of commodities, like gold, without almost all of their negatives.
Property is indeed subject to bubbles, but why wouldn't / couldn't Bitcoin be?
Gold is prone to bubbles as well. Personally I'm not a gold bug and I don't really see why (in the current day and age) it still acts as a safe haven asset.
Ultimately, it has little economic use, meaning most of its value is just derived from it "being gold". Land, that I get, that makes total sense. You can't make more, and you definitely can't make more land in good locations. But gold -- that seems very artificial to me as well.
But you're right, if I had to a pick, Bitcoin probably makes more sense over gold.
