Given the executive order (EO) on Ensuring Responsible Development of Digital Assets (see link below), there's some potential for cryptocurrency to be fully adopted and legitimized. But being a part of the traditional economy requires some level of control and you can't fully control crypto. So the evolution of that EO and other legislative actions will continue to mature and evolve over the next few years. And I'm sure there will be a bunch of nonsense proposals, like the EU’s attempted ban on proof of work (PoW), that might come up from people who have other economic incentives and want to slow the progress.
