Bitcoin is not a viable hedge against a global economic downturn. Just because people push these narratives doesn’t make them true. There is absolutely no evidence that Bitcoin would not crash just as fast or faster than the economy. There are other viable assets that have well studied and well documented track histories.
Crypto currencies are best compared to pink sheets prior to increased regulation, and no one in their right mind would tell you to buy pink sheets to hedge against economic downturn even if their favorite did show a 10000% increase in value.
