The disruption of financial markets may not happen tomorrow, but once it does it will go fast in each market. If there are more efficient venues, competitive market participants will start moving once they realize that they will be at a competitive disadvantage if they don't. When I say efficiency, I am not talking in technical terms and not necessarily on the kind of environments we see on public permissionless chains.
