just had an experiment of "bank run": LNbits - create a mint - distribute the tokens to other wallets to play around - delete the mint, and guess what! all the IOUs left in the wallet are nonredeemable, it's still THERE but you can't cash out or swap out, in real life would be you can't do any transfers or get cash out of the ATMs, which makes me wonder why people trust the banks so much with their money, it's really easy to "shut down" the banks.
