Why not? The bigger problem with scrum is that it does not really work well when the team is remote, distributed and working across various time zones. This is even worse if the project is open source and developers are contributing their own time outside their regular work schedule. When would you run your daily scrum meetings?
Unfortunately, most projects I saw in crypto was what you wrote so they ALWAYS had difficulties with organising the meetings. I think I can state that undistorted Scrum rarely works well in similar projects. But what else could we use in crypto?
