IMO we will a bifurcation between Bitcoin for institutions and Bitcoin for plebs.

Blackrock et al. now have an incentive to defend Bitcoin Core, because if the project fails / stagnates then it hurts their bottom line.

On the other hand, ETF providers and govs now have an incentive to drive plebs away from self-custody. Surveilance and taxation is much easier if you're locked into an ETF. So we could see regulatory attacks on wallets and privacy tech such as coinjoins.
