My not-an-expert 2 sats going forward:

A) stablecoins acting as full reserve banks will create a drop in leverage over time, creating a rush out of speculative assets into yield bearing stablecoins. Dollar eats eats everything.

B) Stablecoin issuers like Circle and Tether get mega filthy rich on treasuries yield and become shadow government style organisations.

C) Bitcoin keeps on trucking as the permissionless alternative, price probably gets a bit more boring and gold-like.

Not mutually exclusive theories.
