Gold's not going to zero, and if they panic perhaps they will buy some gold.

Even in Bitcoin maxi fantasy land metals will have value roughly proportional to the cost to extract fresh metal from the ground (if the metal is too cheap then mining and recycling business shut down, if the metal is too dear then those same companies are profitable and more such are created).

This is why I as a goldbug feel zero pressure to buy bitcoin.]

Sadly, it means that banks of little competence have a chance to make it through fiat collapse.
