The only arguments that I see as valid aganist Bitcoin during a 2008-type clusterfuck unfolding on the near future that i think of right now:
1) Cost of electricity becomes higher due the recession. Im not sure at all how this can be the case, but let's say it gets more expensive. It would need to be a global event to have a real impact on the hashrate. Even with a big loss of hashrate Bitcoin's network is extremely secure at this point. It would be way more convenient than gold specially if you need to cross any borders.
2) Since it's still a new asset, people don't trust it enough and a big amount sells to buy whatever else.. but what is this whatever else that is neutral and decentralized other than gold? and who would be stupid enough to not have some Bitcoin in any case
So yeah, not even valid points.
It's #2. Bitcoin is still experimental. It's versioning implies it's still in beta (and Core developers have said as much). It's only just reaching 10 years old. That's quite unproven. How could you expect the world to view it like gold? And remember, gold crashed in 2008 along with the rest of the market! There's no such thing as the perfect hedge. The flight will be to cash first and foremost.
A major economic contraction means every actor in the economy has less cash to invest (on average). Unemployment rises, consumer and investor demand dries up as people focus on bare necessities. Why would this be good for Bitcoin or any other speculative asset?
Bitcoin's supply is currently inflationary, which means there is already consistent supply that needs to be absorbed to maintain the current price. We're talking about a context where demand should decrease as well (for the same reason that demand for virtually all speculative and investment assets will decrease).
