When banks custody bitcoin and issue notes (receipts, checks, credit, etc.) beyond their reserves, is there a reason to worry things may end similarly to the way it did in the days if the gold standard?

Or does a public ledger keep this in check?

Or does this worry only apply to assets backed by US dollars?

When people discover that the banks issued too much paper, will a bank run for bitcoin be possible without disrupting the rest of the financial system?

Or will a bank run be possible at all?

And does this ultimately raise ir lower the price for thos who hold their assets outside the system?
