I think everyday trust toward to the money is rapidly depleted, and people will finally realised how ignorant and gullible theyre to just earn the IOU garbage fake money, do you think crypto will trigger the complete bank run? Or any other delusional store of value that we dont know yet?
I do think that crypto will be the downfall of fiat, but i don't think that it will lead to banks's downfall, because first by the time crypto starts making a significant impact or comes close to that government will have a back up plan by creating an alternative digital currency that they will backing it up, and that is one of the reason they are not accepting or at least acknowledging currencies like bitcoin, and by that time surely banks will transition from banking fiat to bank whatever digital currency used.
