I think that public/permissionless crypto is going to remain a niche. It's clear that there are too many footguns and failure modes for the average user.

But I think private/permissioned chains will gain some adoption in the background of tradfi, especially for clearing and settlement, collateral management via tokenisation etc. Your bank might eventually use technology developed in crypto, but it'll be called 'distributed ledger technology' or 'tokenisation' rather than crypto because of the negative image.
