Bitcoin only solves things as long a people don't sell at the same time.
We saw what happened last year when that TerraLuna guy sold all his bitcoin reserves in an effort to raise funds to prop up his coin, and in the process tanked bitcoin from $45,000 to $16,000.
It's eerily similar to Silicon Valley Bank panic selling their medium term bonds at a loss.
All these systems are vulnerable to panic sellers.
