Is it dangerous to buy new zone domains? Were there precedents for the disappearance of a domain?

Question

Domain name market

I don't know how this system works.
Now there is a bunch of new domains, such as .paris, .media, .today and others, even more exotic.
So, I wonder if there were situations when a domain appeared, then some company that owned this domain closed or stopped paying fees (as far as I know, this is about several hundred thousand dollars a year) and the domain was closed, and that’s it. domain name owners, who invested effort and money in the promotion of their sites and domains, turned out to be nothing?

Answer 1

Yes, there have been such cases. Not that often, but unpopular zones can be closed (sunset)
As from the side of the registrar (then you can at least transfer to another)
or from the side of the registrar, such as https://iwantmyname.com/blog/sunsetting-of-some-se. ..
