I am using a .top domain for my homelab (because it was cheap). How will existing domains be handled, assuming ICAN shuts down the registrar?
But that poses another problem, assuming you haven't reg it for something like 10 years, suddenly it won't be as cheap anymore if the new registry taking it over decided to hike the fee.
Afaik .top is just really cheap for the 1st year. For subsequent renewal its around $4-5. More stable, less spammy, no looming problem of registry getting revoked .de .be .uk is around $4-5 too.
